Description

Technical Field

[0001] The present invention relates to the technical field of multiphase flow mixed transportation, and in particular to a multiphase flow separation and processing device. Background Art

[0002] Crude oil output is primarily a multiphase mixture of oil, water, and gas, also containing a small amount of sediment. Traditional oil and gas extraction and transportation from oilfields involves separating the oil, gas, and water, then transporting them separately using oil pumps, water pumps, and compressors. This process is complex, requires high investment, and is difficult to operate and maintain.

[0003] Multiphase flow mixing technology, a highly efficient and economical pumping technique developed in recent years, is a trend in oilfield production and transportation technology both domestically and internationally. Multiphase flow transportation places very high demands on equipment stability, requiring long-term, stable operation. Chinese patent CN109114433A discloses a multiphase flow mixing device.

[0072] In this application, the word "exemplary" is used to mean "serving as an example, illustration, or illustration." Any embodiment described in this application as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments. The following description is given to enable any person skilled in the art to make and use the invention. In the following description, details are listed for the purpose of explanation. It should be understood that one of ordinary skill in the art will recognize that the invention can be practiced without these specific details. In other instances, well-known structures and processes are not described in detail to avoid obscuring the description of the invention with unnecessary detail. Therefore, the present invention is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.

[0073] like Figure 1 and Figure 4As shown, the embodiment of the present application provides a multiphase flow distribution processing device, including a mixing mechanism 10, the mixing mechanism 10 includes a first tank body 13, a second tank body 14, a third tank body 15 and a reversing mechanism 16, the first tank body 13 and the second tank body 14 are respectively connected to the third tank body 15, the first tank body 13 and the third tank body 15 form a first processing mechanism 11, the second tank body 14 and the third tank body 15 form a second processing mechanism 12; the reversing mechanism 16 connects the first processing mechanism 11 and the second processing mechanism 12, and the reversing mechanism 16 connects the first processing mechanism 11 and the second processing mechanism 12. 6 drives the liquid mixture of different densities in the first processing mechanism 11 and the second processing mechanism 12 to circulate back and forth between the first processing mechanism 11 and the second processing mechanism 12, so that the liquid mixture is separated from the first processing mechanism 11 and the second processing mechanism 12 and the gas and / or liquid of different densities are discharged; the distribution mechanism 20 is connected to the first tank body 13, the second tank body 14 and the third tank body 15 to distribute the gas and / or liquid of different densities separated from the first tank body 13, the second tank body 14 and the third tank body 15.

[0074] The multiphase flow distribution and processing device provided in the embodiment of the present application is suitable for conveying gas, liquid, liquid-solid, or a multiphase flow mixture containing both gas and liquid, or a multiphase flow mixture containing solid, gaseous and liquid materials or other fluid materials. Unless otherwise specified, the multiphase flow mixture will be described as a mixture containing both gas and liquid.

[0075] The specific structures of the first tank body 13 , the second tank body 14 and the third tank body 15 are not particularly limited, as long as they can be used to accommodate the multiphase flow mixture and facilitate the transportation of the multiphase flow mixture.

[0076] In some embodiments of the present application, specifically, the first tank body 13 and the second tank body 14 are respectively connected to the third tank body 15 via a reversing mechanism 16. The reversing mechanism 16 can drive the liquid mixture to flow in the mixing and transporting mechanism 10 and change the flow direction of the liquid mixture in the mixing and transporting mechanism 10. The reversing mechanism 16 drives the liquid mixture from the first tank body 13 or the second tank body 14 to the third tank body 15. When the third tank body 15 is filled with the liquid mixture, it is returned to the first tank body 13 or the second tank body 14 through the reversing mechanism 16, so that the first tank body 13 or the second tank body 14 forms a vacuum suction chamber or a compression discharge chamber.

[0077] The following description will be made by taking the first tank body 13 as a vacuum suction chamber and the second tank body 14 as a compression discharge chamber as an example, in combination with the above specific structure;

[0078] When the first tank body 13 is a suction chamber, the liquid mixture in the first tank body 13 is sucked out by the drive mechanism, and the liquid mixture enters the third tank body 15 along the pipeline group of the reversing mechanism 16. When the liquid mixture fills the third tank body 15, the high oil-water mixture separated by sedimentation in the third tank body 15 is continuously squeezed out of the third tank body 15, and the squeezed high oil-water mixture enters the second tank body 14 along the pipeline group of the reversing mechanism 16. Under the action of the continuously entering high oil-water mixture, the second tank body 14 forms a positive pressure cavity, and the second tank body 14 compresses and discharges the gas and / or liquid at the top thereof.

[0079] By providing a third tank 15, the multiphase flow separation and processing device allows both the first tank 13 and the second tank 15 to accommodate the multiphase flow mixture during feeding, i.e., the first processing mechanism 11, effectively increasing the feed rate of the multiphase flow mixing device. Similarly, when the second tank 14 is discharging material, the third tank 15 continuously discharges liquid into the second tank 14, and the liquid in the third tank 15 can be discharged through the second tank 14, effectively increasing the discharge rate of the multiphase flow mixing device. At the same time, the liquid mixture in the first tank 13 and the second tank 14 flows to the third tank 15 for water separation, further increasing the efficiency of the multiphase flow mixing device in pumping oil and gas.

[0080] It can be understood that when pumping the same volume of crude oil mixture, the multiphase flow mixing and delivery device of the present invention requires fewer reversals than conventional multiphase flow mixing and delivery devices. This effectively reduces the number of reversals and the damage to the equipment caused by the impact of reversal operations, thereby extending the service life of the equipment and improving its reliability. Furthermore, the reduced number of reversals in the multiphase flow mixing and delivery device also reduces the number of valve openings and closings on the pipeline assembly, thereby reducing the impact of valve openings and closings on the pumping efficiency of the multiphase flow mixture.

[0081] Specifically, the multiphase flow distribution and processing device also includes an input pipeline group and an output pipeline group. The input pipeline group is connected to the first tank 13 and the second tank 14 respectively. The first tank 13 and the second tank 14 are each connected to the distribution mechanism 20 via the output pipeline group. The third tank 15 is connected to the distribution mechanism 20 via the water diversion pipeline. The input pipeline group is equipped with a control valve for controlling the opening and closing of the input pipeline group, thereby controlling the input of the crude oil mixture into the multiphase flow distribution and processing device; the output pipeline group is equipped with a control valve for controlling the opening and closing of the output pipeline group, thereby controlling the output of gas and / or liquid from the multiphase flow distribution and processing device.

[0082] The distribution and processing of the multiphase flow mixture also includes the steps of initial input, sedimentation separation, initial circulation, water separation, distribution of gas and / or liquid, reversing operation and reciprocating circulation. The following is the specific implementation process of each step.

[0083] Initially, the crude oil mixture is input into the first tank 13 and the second tank 14 through the input pipeline group. Preferably, the crude oil mixture fills the first tank 13 and the second tank 14. This configuration can minimize the volume of air in the first tank 13 and the second tank 14, thereby reducing the possibility of air entering the reversing mechanism 16 and damaging it. In other embodiments of the present application, the input crude oil mixture can also partially fill the first tank 13 and the second tank 14, which is not limited here. In other embodiments of the present application, the multiphase flow mixture initially input into the first tank 13 and the second tank can also be a substance such as water, which is not limited here.

[0084] Sedimentation separation: During the process of the crude oil mixture being input and filling the first tank body 13 and the second tank body 14, the various substances in the crude oil mixture continue to settle and separate in the first tank body 13 and the second tank body 14 according to their different densities, and a gas located in the upper part of the first tank body 13 and the second tank body 14 and a liquid mixture located in the lower part of the first tank body 13 and the second tank body 14 are initially separated. The liquid mixture is generally a mixture of oil and water. In other embodiments of the present application, the input crude oil mixture may not contain gas, which is not limited here. In other embodiments of the present application, the liquid mixture may be substances such as water or oil, which is not limited here.

[0085] During the initial cycle, after the first and second tanks 13, 14 are filled with the crude oil mixture, the reversing mechanism 16 randomly selects either the first tank 13 or the second tank 14 to draw the liquid mixture. Unless otherwise specified, the following description uses the first tank 13 as the initial draw. The liquid mixture, which has undergone preliminary sedimentation and separation in the first tank 13, is continuously drawn into the third tank 15, creating a negative pressure chamber in the first tank 13. The control valve on the inlet pipeline connecting the first tank 13 is opened, allowing the first tank 13 to continuously draw in additional crude oil mixture.

[0086] Separate water. When the third tank body 15 is continuously fed with a liquid mixture, the various substances in the liquid mixture continue to settle and separate in the third tank body 15 according to their densities, and further separate the high-oil-water mixture at the top of the third tank body 15 and the water at the bottom of the third tank body 15. When the third tank body 15 is filled with the liquid mixture, under the pressure of the liquid mixture continuously fed into the third tank body 15, the high-oil-water mixture at the top of the third tank body 15 is returned to the second tank body 14 (i.e., the tank body from which the liquid mixture has not been sucked out) through the reversing mechanism 16. In addition, during the process of vacuum suction by the first tank body 13 and compression discharge by the third tank body 15, the second tank body 14 also continues to undergo sedimentation separation. Therefore, the sedimentation separation time in the second tank body 14 is longer than that in the first tank body 13 and the second tank body 14, so the sedimentation separation effect in the second tank body 14 is better. The second tank body 14 is subjected to sedimentation separation to form a gas and / or oil mixture at the top and water at the bottom. Under the pressure of the high oil-water mixture input by the third tank body 15, the second tank body 14 forms a positive pressure cavity, and the gas and / or oil mixture at the top of the second tank body 14 is squeezed and discharged to the distribution mechanism 20.

[0087] During the process of continuously inputting a high-oil-water mixture and continuously discharging a high-oil-water mixture into the second tank 14, it is understood that since the second tank 14 is continuously discharging the gas and / or oil mixture located in the upper portion after a longer period of sedimentation and separation, and inputting the high-oil-water mixture after a relatively shorter period of sedimentation and separation, the water content of the second tank 14 increases during the sedimentation and separation process. When the oil-water interface height (i.e., the oil-water separation interface height) in the second tank 14 reaches a preset reversing threshold, the reversing operation and water removal operation are performed.

[0088] The reversing operation closes the control valve connecting the second tank 14 to the output pipeline group, closes the control valve connecting the reversing mechanism 16 to the first tank 13 for the liquid mixture being sucked out, closes the control valve connecting the input pipeline group to the first tank 13, and closes the control valve connecting the reversing mechanism 16 to the second tank 14 for returning the high-oil-water mixture; then opens the control valve connecting the reversing mechanism 16 to the second tank 14 for the liquid mixture being sucked out, opens the control valve connecting the input pipeline group to the second tank 14, and opens the control valve connecting the reversing mechanism 16 to the first tank 13 for returning the high-oil-water mixture. That is, the liquid mixture in the mixing mechanism 10 is initially sucked out of the first tank 13 to the third tank 15. After the third tank 15 is filled with the liquid mixture, it is compressed and discharged from the third tank 15 to the second tank 14. The gas and / or oil mixture at the top of the second tank 14, which has been settling and separated for the longest time, is compressed and discharged from the second tank 14. The liquid mixture is then drawn from the second tank 14 into the third tank 15. Once the third tank 15 is filled with the liquid mixture, it is compressed and discharged from the third tank 15 into the first tank 13. The first tank 13 then compresses and discharges the gas and / or oil mixture at the top of the first tank 13, which has been settling and separating for the longest time after the reversal. The operation of the liquid mixture after the reversal is similar to that before the reversal and will not be elaborated on here.

[0089] During the water removal operation, the control valve of the third tank body 15 connected to the distribution mechanism 20 is opened to control the third tank body 15 to remove the water at the bottom. When the oil-water interface height value of the water removal of the third tank body 15 reaches the preset stop water removal interface height value, the water removal operation is stopped.

[0090] The reciprocating cycle, as can be understood, is that after the reversal and water removal operations are completed (i.e., the initial cycle), the liquid mixture flows from the first processing mechanism 11 to the second processing mechanism 12 in the mixing mechanism 10, completing the gas and / or liquid processing, and then enters the second cycle. That is, it flows from the second processing mechanism 12 to the first processing mechanism 11, completing the gas and / or liquid processing. After the initial cycle, the second cycle and all subsequent reciprocating cycles are the same or similar to the initial cycle, and will not be elaborated on here.

[0091] like Figure 1As shown, in other embodiments of the present application, the reversing mechanism 16 includes a power pump 161, a switching pipeline group 162, and a first control valve 163. Specifically, the power pump 161 and the first control valve 163 are provided on the switching pipeline group 162, and the switching pipeline group 162 is connected to the first tank body 13, the second tank body 14, and the third tank body 15; the first control valve 163 is used to control the flow direction of the liquid mixture between the first tank body 13 and the third tank body 15 or between the second tank body 14 and the third tank body 15. The power pump 161 drives the liquid mixture to flow between the first tank body 13 and the third tank body 15 or between the second tank body 14 and the third tank body 15 according to the flow direction of the liquid mixture.

[0092] This allows for a smoother and more controllable process of aspirating the liquid mixture from the first or second tank 13, 14 to the third tank 15, and returning the high-oil-water mixture from the third tank 15 to the first or second tank 13, 14, where the liquid mixture has not been aspirated. This results in a more stable distribution of the crude oil mixture. Furthermore, power pump 161 operates entirely under conditions with no gas, low water content, or no water, minimizing the impact of water and / or gas on power pump 161 and improving its reliability.

[0093] Furthermore, power pump 161 may also be a centrifugal pump, which features high speed, compact size, light weight, high efficiency, high flow rate, simple structure, smooth infusion, stable performance, easy operation, and convenient maintenance. Power pump 161 may also be a multiphase mixed flow pump, etc., without limitation herein. Furthermore, power pump 161 may also be installed on the third pipeline 171 set, without limitation herein.

[0094] In other embodiments of the present application, the switching pipeline assembly 162 includes a first pipeline 1621, one end of which connects the first tank 13 and the second tank 14, and the other end is connected to the power pump 161. A second pipeline 1622, one end of which connects the third tank 15, and the other end is connected to the power pump 161. The liquid mixture flows along the first tank 13 through the first pipeline 1621, the power pump 161, and the second pipeline 1622 in sequence into the third tank 15; alternatively, the liquid mixture flows along the second tank 14 through the first pipeline 1621, the power pump 161, and the second pipeline 1622 in sequence into the third tank 15.

[0095] The reversing mechanism 16 includes a return pipeline group 17 for transporting the high oil-water mixture in the third tank body 15 to the first tank body 13 or the second tank body 14; when reversing, the power pump 161 drives the liquid mixture along the first tank body 13 to flow into the third tank body 15, and the high oil-water mixture flows from the third tank body 15 to the second tank body 14 along the return pipeline group 17; or, the power pump 161 drives the liquid mixture along the second tank body 14 to flow into the third tank body 15, and the high oil-water mixture flows from the third tank body 15 to the first tank body 13 along the return pipeline group 17.

[0096] The return pipeline group 17 includes a third pipeline 171 , one end of which is connected to the first tank 13 and the second tank 14 and the other end is connected to the third tank 15 ; and a plurality of second control valves 172 , each of which is disposed on the third pipeline 171 .

[0097] The multiphase flow distribution processing device is provided with a switching pipeline group 162 and a return pipeline group 17, so that the liquid mixture can flow smoothly in the first tank body 13, the second tank body 14 and the third tank body 15, thereby improving the control efficiency.

[0098] Furthermore, the first pipeline 1621 is provided with a first branch pipe and a second branch pipe at one end away from the power pump 161, and the third pipeline 171 is provided with a third branch pipe and a fourth branch pipe at one end away from the third tank body 15; the first tank body 13 is provided with a first circulation inlet and a second circulation outlet on the side wall, and the second tank body 14 is provided with a second circulation inlet and a second circulation outlet on the side wall. Specifically, a first branch pipe connects to the first circulation outlet, a second branch pipe connects to the second circulation outlet, and a first control valve 163 controls the opening and closing of the first and / or second branch pipes. A third branch pipe connects to the first circulation inlet, and a fourth branch pipe connects to the second circulation inlet. Multiple second control valves 172 control the opening and closing of the first and / or second branch pipes, thereby controlling the liquid mixture to flow from the first tank 13 through the first branch pipe, first pipeline 1621, power pump 161, and second pipeline 1622, into the third tank 15. Alternatively, the liquid mixture can flow from the second tank 14 through the second branch pipe, first pipeline 1621, power pump 161, and second pipeline 1622, into the third tank 15. A reversing mechanism 16 allows the high-oil-water mixture to be returned to the first tank 13 via the third pipeline 171 and the third branch pipe, or to be returned to the second tank 14 via the third pipeline 171 and the fourth branch pipe.

[0099] The reversing mechanism 16 is provided with a first branch pipe connected to the first circulation outlet, a second branch pipe connected to the second circulation outlet, a third branch pipe connected to the first circulation inlet, and a fourth branch pipe connected to the second circulation inlet, so that the liquid mixture output from the first tank body 13 or the second tank body 14 and the high oil-water mixture input into the first tank body 13 or the second tank body 14 pass through different pipelines respectively, so that the distribution pipelines correspond to each other one by one, which facilitates the control and maintenance of the pipelines and makes the layout more reasonable.

[0100] Furthermore, the first circulation inlet and the first circulation outlet can also be the same channel - the first circulation outlet; the second circulation inlet and the second circulation outlet can also be the same channel - the second circulation outlet. From the above circulation process, it can be seen that when the liquid mixture in the first treatment mechanism 11 flows to the second treatment mechanism 12, the first tank body 13 is the circulation output tank body, and the second tank body 14 is the circulation input tank body; after the reversing operation is performed, when the liquid mixture in the second treatment mechanism 12 flows to the first treatment mechanism 11, the first tank body 13 is the circulation input tank body, and the second tank body 14 is the circulation output tank body.

[0101] It is understood that during the dispensing process of the mixed-transfer mechanism 10, only one circulation channel in each of the first tank body 13 and the second tank body 14 is open. For example, during the process of the liquid mixture in the first treatment mechanism 11 flowing to the second treatment mechanism 12, the first circulation outlet of the first tank body 13 for circulating output is open, and the second circulation inlet of the second tank body 14 for circulating input is open; while during the process of the liquid mixture in the second treatment mechanism 12 flowing to the first treatment mechanism 11, the first circulation inlet of the first tank body 13 for circulating input is open, and the second circulation outlet of the second tank body 14 for circulating output is open. In other words, the circulation inlet and circulation outlet are not used simultaneously, so they can be combined into a circulation port, reducing the number of openings in the first tank body 13 and the second tank body 14, lowering manufacturing costs, and improving the reliability of the tank bodies.

[0102] In other embodiments of the present application, the first control valve 163 is a three-way valve arranged on the first pipeline 1621; wherein, the three-way valve connects the first tank body 13 and the first pipeline 1621 and closes the second tank body 14 and the first pipeline 1621, and the power pump 161 drives the liquid mixture to flow along the first tank body 13 through the first pipeline 1621, the power pump 161 and the second pipeline 1622 in sequence into the third tank body 15; or, the three-way valve connects the second tank body 14 and the first pipeline 1621 and closes the first tank body 13 and the first pipeline 1621, and the power pump 161 drives the liquid mixture to flow along the first tank body 13 through the first pipeline 1621, the power pump 161 and the second pipeline 1622 in sequence into the third tank body 15.

[0103] Furthermore, the three ends of the three-way valve are connected to the first branch pipe, the second branch pipe and the first pipeline 1621 respectively. By setting the three-way valve, the number of control valves can be reduced, and the installation and maintenance costs can be reduced.

[0104] In other embodiments of the present application, the first control valve 163 is a pair of power valves arranged on the first pipeline 1621; wherein, one power valve connects the first tank body 13 and the first pipeline 1621 and the other power valve closes the second tank body 14 and the first pipeline 1621, and the power pump 161 drives the liquid mixture to flow along the first tank body 13 through the first pipeline 1621, the power pump 161 and the second pipeline 1622 in sequence into the third tank body 15; or, one power valve connects the second tank body 14 and the first pipeline 1621 and the other power valve closes the first tank body 13 and the first pipeline 1621, and the power pump 161 drives the liquid mixture to flow along the first tank body 13 through the first pipeline 1621, the power pump 161 and the second pipeline 1622 in sequence into the third tank body 15.

[0105] Furthermore, a pair of power valves provided on first pipeline 1621 can be provided on the first branch pipe and the second branch pipe, respectively, to control the opening and closing of the first branch pipe and the second branch pipe, respectively. Separate power valves can effectively reduce the impact of damage to valves such as three-way valves on other pipelines, thereby improving the reliability of reversing mechanism 16.

[0106] In other embodiments of the present application, the second control valve 172 is a three-way valve arranged on the third pipeline 171, wherein the three-way valve connects the first tank body 13 and the third pipeline 171 and closes the second tank body 14 and the third pipeline 171, and the power pump 161 drives the liquid mixture into the third tank body 15, and squeezes the high oil-water mixture on the top of the third tank body 15 along the third tank body 15 and flows into the first tank body 13 along the third pipeline 171 and the third branch pipe in sequence; or, the three-way valve connects the second tank body 14 and the third pipeline 171 and closes the first tank body 13 and the third pipeline 171, and the power pump 161 drives the liquid mixture into the third tank body 15, and squeezes the high oil-water mixture on the top of the third tank body 15 along the third tank body 15 and flows into the second tank body 14 along the third pipeline 171 and the fourth branch pipe in sequence.

[0107] Furthermore, the three ends of the three-way valve are connected to the first branch pipe, the second branch pipe, and the first pipeline 1621. By providing a three-way valve, the number of control valves can be reduced, reducing installation and maintenance costs. Furthermore, the second control valve 172 can also be a power valve, which is not limited here.

[0108] In other embodiments of the present application, the second control valve 172 also includes a first return valve, which is arranged at one end of the third pipeline 171 away from the third branch and the fourth branch, and is used to control the opening and closing of the third pipeline 171. Furthermore, the first return valve can also be a power valve, which is not limited here.

[0109] In other embodiments of the present application, the reversing mechanism 16 further includes a plurality of first valve groups 164 disposed on the first pipeline 1621 and the second pipeline 1622 for use during maintenance. The reversing mechanism 16 further includes a plurality of second valve groups 1711 disposed on the first pipeline 1621 and the second pipeline 1622 for use during maintenance.

[0110] Specifically, a maintenance valve is provided on each side of the power pump 161 in the first pipeline 1621. When the power pump 161 malfunctions and requires inspection and maintenance, the maintenance inspection of the power pump 161 can be completed by simply closing the maintenance valves on both sides of the power pump 161, thereby improving the efficiency of inspection and maintenance and enhancing the reliability of the reversing mechanism 16. A maintenance valve is provided at one end of the first branch pipe near the first circulation outlet, and a maintenance valve is provided at one end of the second branch pipe near the second circulation outlet. These multiple maintenance valves constitute the first valve group 164. The combination of multiple maintenance valves can reduce the need to disassemble other pipelines when the switching pipeline group 162 requires maintenance and inspection, thereby improving the efficiency of inspection and maintenance, ensuring that other pipelines are not damaged, and improving the reliability of the reversing mechanism 16.

[0111] Specifically, a maintenance valve is provided at one end of the third branch pipe near the first circulation inlet, and a maintenance valve is provided at one end of the fourth branch pipe near the second circulation inlet. These multiple maintenance valves constitute second valve group 1711. This combination of multiple maintenance valves reduces the need to disassemble other pipelines when switching pipeline group 162 requires maintenance and inspection, thereby improving the efficiency of inspection and maintenance, ensuring that other pipelines are not damaged, and enhancing the reliability of reversing mechanism 16.

[0112] like Figure 2 As shown, in other embodiments of the present application, the first tank 13 and the second tank 14 are respectively connected to the distribution mechanism 20 via an output pipeline assembly, and the third tank 15 is connected to the distribution mechanism 20 via a water distribution pipeline. The first tank 13 or the second tank 14 outputs gas and / or liquid to the distribution mechanism 20 via the output pipeline assembly, and the third tank 15 outputs water to the distribution mechanism 20 via the water distribution pipeline. In this way, water can be quickly separated from the crude oil mixture and the gas and / or liquid after the water is separated can be output, completing the distribution of gas and / or liquid of different densities.

[0113] In other embodiments of the present application, the mixed delivery mechanism 10 further includes a backup reversing mechanism 18 disposed in parallel with the backup reversing mechanism 18 on the first processing mechanism 11 and the second processing mechanism 12. During reversal, only one of the backup reversing mechanism 18 or the backup reversing mechanism 18 is activated. The structure and reversing function of the backup reversing mechanism 18 are the same or similar to those of the backup reversing mechanism 18 described above. Therefore, the reversing steps implemented by the backup reversing mechanism 18 will not be described in detail here. The following primarily describes the structure of the backup reversing mechanism 18 and the connections between the backup reversing mechanism 18 and the first tank 13, the second tank 14, the third tank 15, and the distribution mechanism 20.

[0114] The backup switching pipeline assembly 182 includes a fifth pipeline 1821, one end of which connects to the first tank 13 and the second tank 14, and the other end is connected to the backup power pump 181. A sixth pipeline 1822, one end of which connects to the third tank 15, and the other end is connected to the backup power pump 181. The liquid mixture flows from the first tank 13 through the fifth pipeline 1821, the backup power pump 181, and the sixth pipeline 1822 in sequence into the third tank 15; alternatively, the liquid mixture flows from the second tank 14 through the fifth pipeline 1821, the backup power pump 181, and the sixth pipeline 1822 in sequence into the third tank 15.

[0115] The standby reversing mechanism 18 includes a standby return pipeline group 19 for transporting the high oil-water mixture in the third tank body 15 to the first tank body 13 or the second tank body 14; during reversing, the standby power pump 181 drives the liquid mixture along the first tank body 13 to flow into the third tank body 15, and the high oil-water mixture flows from the third tank body 15 to the second tank body 14 along the standby return pipeline group 19; or, the standby power pump 181 drives the liquid mixture along the second tank body 14 to flow into the third tank body 15, and the high oil-water mixture flows from the third tank body 15 to the first tank body 13 along the standby return pipeline group 19.

[0116] The backup return pipeline group 19 includes a seventh pipeline 191 , one end of which is connected to the first tank body 13 and the second tank body 14 and the other end is connected to the third tank body 15 ; and a plurality of fourth control valves 192 , each of which is disposed on the seventh pipeline 191 .

[0117] The mixing mechanism 10 is provided with a standby switching pipeline group 182 and a standby return pipeline group 19, so that the liquid mixture can flow smoothly in the first tank body 13, the second tank body 14 and the third tank body 15, thereby improving control efficiency.

[0118] Furthermore, the fifth pipeline 1821 is provided with a fifth branch and a sixth branch at one end away from the backup power pump 181, and the seventh pipeline 191 is provided with a seventh branch and an eighth branch at one end away from the third tank body 15; a third circulation inlet and a third circulation outlet are provided on the side wall of the first tank body 13, and a fourth circulation inlet and a fourth circulation outlet are provided on the side wall of the second tank body 14.

[0119] Specifically, the fifth branch pipe connects to the third circulation outlet, the sixth branch pipe connects to the fourth circulation outlet, and the third control valve 183 controls the opening and closing of the fifth and / or sixth branches. The seventh branch pipe connects to the third circulation inlet, and the eighth branch pipe connects to the fourth circulation inlet. Multiple fourth control valves 192 control the opening and closing of the fifth and / or sixth branches. This controls the liquid mixture to flow from the first tank 13 sequentially through the fifth branch pipe, the fifth pipeline 1821, the backup power pump 181, and the sixth pipeline 1822 into the third tank 15. Alternatively, the liquid mixture flows from the second tank 14 sequentially through the sixth branch pipe, the fifth pipeline 1821, the backup power pump 181, and the sixth pipeline 1822 into the third tank 15. The highly oily-water mixture is controlled to be returned to the first tank 13 via the seventh pipeline 191 and the seventh branch pipe along the third tank 15. Alternatively, the highly oily-water mixture is controlled to be returned to the second tank 14 via the seventh pipeline 191 and the eighth branch pipe along the third tank 15.

[0120] The standby reversing mechanism 18 is provided with a fifth branch pipe connected to the third circulation outlet, a sixth branch pipe connected to the fourth circulation outlet, a seventh branch pipe connected to the third circulation inlet, and an eighth branch pipe connected to the fourth circulation inlet, so that the liquid mixture output from the first tank body 13 or the second tank body 14 and the high oil-water mixture input into the first tank body 13 or the second tank body 14 pass through different pipelines respectively, so that the distribution pipelines correspond to each other one by one, which facilitates the control and maintenance of the pipelines and makes the layout more reasonable.

[0121] like Figure 2 and Figure 5 As shown, further, the third circulation inlet and the third circulation outlet can also be the same channel - the third circulation outlet; the fourth circulation inlet and the fourth circulation outlet can also be the same channel - the fourth circulation outlet. Similarly, the principles of the first circulation outlet and the second circulation outlet described above are similar and have been explained in detail, so they will not be elaborated on here.

[0122] In other embodiments of the present application, the third control valve 183 is a three-way valve arranged on the fifth pipeline 1821; wherein, the three-way valve connects the first tank body 13 and the fifth pipeline 1821 and closes the second tank body 14 and the fifth pipeline 1821, and the backup power pump 181 drives the liquid mixture to flow along the first tank body 13 through the fifth pipeline 1821, the backup power pump 181 and the sixth pipeline 1822 in sequence into the third tank body 15; or, the three-way valve connects the second tank body 14 and the fifth pipeline 1821 and closes the first tank body 13 and the fifth pipeline 1821, and the backup power pump 181 drives the liquid mixture to flow along the first tank body 13 through the fifth pipeline 1821, the backup power pump 181 and the sixth pipeline 1822 in sequence into the third tank body 15.

[0123] Furthermore, the three ends of the three-way valve are connected to the fifth branch pipe, the sixth branch pipe and the fifth pipeline 1821 respectively. By setting the three-way valve, the number of control valves can be reduced, and the installation and maintenance costs can be reduced.

[0124] In other embodiments of the present application, the third control valve 183 is a pair of power valves arranged on the fifth pipeline 1821; wherein, one power valve connects the first tank body 13 and the fifth pipeline 1821 and the other power valve closes the second tank body 14 and the fifth pipeline 1821, and the backup power pump 181 drives the liquid mixture to flow along the first tank body 13 through the fifth pipeline 1821, the backup power pump 181 and the sixth pipeline 1822 in sequence into the third tank body 15; or, one power valve connects the second tank body 14 and the fifth pipeline 1821 and the other power valve closes the first tank body 13 and the fifth pipeline 1821, and the backup power pump 181 drives the liquid mixture to flow along the first tank body 13 through the fifth pipeline 1821, the backup power pump 181 and the sixth pipeline 1822 in sequence into the third tank body 15.

[0125] Furthermore, a pair of power valves provided on the fifth pipeline 1821 can be installed on the fifth branch and the sixth branch, respectively, to control the opening and closing of the fifth branch and the sixth branch. The separate power valves can effectively reduce the impact of damage to valves such as three-way valves on other pipelines, thereby improving the reliability of the backup reversing mechanism 18.

[0126] In other embodiments of the present application, the fourth control valve 192 is a three-way valve arranged on the seventh pipeline 191, wherein the three-way valve connects the first tank body 13 and the seventh pipeline 191 and closes the second tank body 14 and the seventh pipeline 191, and the backup power pump 181 drives the liquid mixture into the third tank body 15, and squeezes the high oil-water mixture on the top of the third tank body 15 along the third tank body 15 in sequence along the seventh pipeline 191 and the seventh branch pipe into the first tank body 13; or, the three-way valve connects the second tank body 14 and the seventh pipeline 191 and closes the first tank body 13 and the seventh pipeline 191, and the backup power pump 181 drives the liquid mixture into the third tank body 15, and squeezes the high oil-water mixture on the top of the third tank body 15 along the third tank body 15 in sequence along the seventh pipeline 191 and the eighth branch pipe into the second tank body 14.

[0127] Furthermore, the three ends of the three-way valve are connected to the fifth branch pipe, the sixth branch pipe, and the fifth pipeline 1821, respectively. By providing a three-way valve, the number of control valves can be reduced, reducing installation and maintenance costs. Furthermore, the fourth control valve 192 can also be a power valve, which is not limited here.

[0128] In other embodiments of the present application, the fourth control valve 192 also includes a first return valve, which is arranged at one end of the seventh pipeline 191 away from the seventh branch and the eighth branch, and is used to control the opening and closing of the seventh pipeline 191. Furthermore, the first return valve can also be a power valve, which is not limited here.

[0129] In other embodiments of the present application, the backup reversing mechanism 18 further includes a plurality of third valve groups 184 disposed on the fifth pipeline 1821 and the sixth pipeline 1822 for use during maintenance. The backup reversing mechanism 18 further includes a plurality of fourth valve groups 1911 disposed on the fifth pipeline 1821 and the sixth pipeline 1822 for use during maintenance.

[0130] Specifically, a maintenance valve is provided on each side of the backup power pump 181 of the fifth pipeline 1821. When the backup power pump 181 malfunctions and requires inspection and maintenance, the maintenance inspection of the backup power pump 181 can be completed by simply closing the maintenance valves on both sides of the backup power pump 181. This improves the efficiency of inspection and maintenance and enhances the reliability of the backup reversing mechanism 18. A maintenance valve is provided at the end of the fifth branch pipe near the first circulation outlet, and a maintenance valve is provided at the end of the sixth branch pipe near the second circulation outlet. These multiple maintenance valves constitute the third valve group 184. The combination of multiple maintenance valves reduces the need to disassemble other pipelines when the backup switching pipeline group 182 requires maintenance and inspection, thereby improving the efficiency of inspection and maintenance, ensuring that other pipelines are not damaged, and enhancing the reliability of the backup reversing mechanism 18.

[0131] Specifically, a maintenance valve is provided at the end of the seventh branch pipe near the third circulation inlet, and a maintenance valve is provided at the end of the eighth branch pipe near the fourth circulation inlet. These multiple maintenance valves constitute fourth valve assembly 1911. This combination of multiple maintenance valves reduces the need to disassemble other pipelines when standby switching pipeline assembly 182 requires maintenance and inspection, thereby improving the efficiency of inspection and maintenance, ensuring that other pipelines are not damaged, and enhancing the reliability of standby reversing mechanism 18.

[0132] Furthermore, the first control valve 163, the second control valve 172, the third control valve 183, the fourth control valve 192, the first valve group 164, the second valve group 1711, the third valve group 184 and the fourth valve group 1911 can all be controlled manually, and can also be remotely controlled by electric, Bluetooth, wireless, etc., which are not limited here.

[0133] In some other embodiments of the present application, a first inlet and a first outlet are provided at the top of the first pipeline 1621, and a second inlet and a second outlet are provided at the top of the second tank body 14. The input pipeline group also includes a first input branch pipe and a second input branch pipe. One end of the first input branch pipe is connected to the first inlet, and the other end is connected to the input pipeline group; one end of the second input branch pipe is connected to the second inlet, and the other end is connected to the input pipeline group. The first input branch pipe and the second input branch pipe are respectively provided with a control valve group to control the opening and closing of the pipeline. The output pipeline group also includes a first output branch pipe and a second output branch pipe. One end of the first output branch pipe is connected to the first outlet, and the other end is connected to the output pipeline group; one end of the second output pipeline group is connected to the second outlet, and the other end is connected to the output pipeline group. The first output branch pipe and the second input and output pipe are respectively provided with a control valve group to control the opening and closing of the pipeline.

[0134] Specifically, the control valve group on the first input branch and the second input branch can be a one-way valve and a control valve. Preferably, the first input branch and the second input branch can be connected in parallel to form a pipeline to connect the input pipeline group, and a control valve can be set on this pipeline. In this way, not only can the control needs be met, but also the number of valves can be reduced, the cost can be reduced, and the control is convenient. Furthermore, the control valve can be replaced with a three-way valve, and the three ends of the three-way valve are respectively connected to the input pipeline group, the first input branch and the second input branch, which are not limited here. The structural arrangement of the control valve group on the first output branch and the second output branch realizes functions similar to or the same as those of the control valve group on the first input branch and the second input branch, and no further elaboration will be given here.

[0135] In other embodiments of the present application, the first outlet further includes a first gas outlet and a first oil outlet, and the second outlet further includes a second gas outlet and a second oil outlet; the first output branch includes a first gas outlet and a second gas outlet, and the second output branch includes a first oil outlet and a second oil outlet. The first gas outlet connects to the first gas outlet, the second gas outlet connects to the second gas outlet, the first oil outlet connects to the first oil outlet, and the second oil outlet connects to the second oil outlet. Control valve groups are provided on the first gas outlet, the second gas outlet, the first oil outlet, and the second oil outlet to control the opening and closing of the pipelines.

[0136] Specifically, the control valve assembly on the first and second gas branch pipes can consist of a one-way valve and a control valve. Preferably, the first and second gas branch pipes can be connected in parallel to form a single pipeline connected to the output pipeline assembly, and a control valve can be installed on this pipeline. This not only meets control requirements but also reduces the number of valves, lowers costs, and facilitates control. Furthermore, the control valve can be replaced with a three-way valve, with the three ends of the three-way valve respectively connected to the output pipeline assembly, the first gas branch pipe, and the second gas branch pipe. This is not limited here.

[0137] Specifically, the control valves on the first and second oil branch pipes can be control valves. Preferably, the first and second oil branch pipes can be connected in parallel to form a single pipeline connected to the output pipeline group, and a control valve can be installed on this pipeline. This not only meets control requirements but also reduces the number of valves, lowers costs, and facilitates control. Furthermore, the control valve can be replaced with a three-way valve, with the three ends of the three-way valve respectively connected to the output pipeline group, the first oil branch pipe, and the second oil branch pipe, without limitation here.

[0138] In other embodiments of the present application, the first inlet and the first outlet can also be the same channel—the first inlet and outlet. As can be seen from the cyclic process described above, before reversing, the crude oil mixture enters the first tank body 13, and the second tank body 14 outputs gas and / or liquid; after reversing, the crude oil mixture enters the second tank body 14, and the first tank body 13 outputs gas and / or liquid. That is, the first inlet and the second outlet are not used simultaneously, so they can be combined into the first inlet and outlet, reducing the number of openings in the first tank body 13 and the second tank body 14, reducing manufacturing costs, and improving the reliability of the tanks. Similarly, the second inlet and the second outlet can also be combined into the second inlet and outlet.

[0139] like Figure 1 As shown, in other embodiments of the present application, the mixing mechanism 10 also includes a first liquid level detector 41 arranged on the first tank body 13 and a second liquid level detector 42 arranged on the second tank body 14, and the start and stop of the reversing mechanism 16 are controlled according to the liquid level height detected by the first liquid level detector 41 or the second liquid level detector 42.

[0140] Specifically, the first liquid level detector 41 is used to detect the liquid level of the water in the first tank body 13, and the second liquid level detector 42 is used to detect the liquid level of the water in the second tank body 14. When the liquid mixture flows from the first processing mechanism 11 to the second processing mechanism 12, the second liquid level detector 42 is activated and detects in real time. As described above, the water content in the second tank body 14 increases with the input of the high-oil-water mixture in the third tank body 15. Therefore, when the second liquid level detector 42 detects that the liquid level of the water in the second tank body 14 (i.e., the height of the separation interface between oil and water) reaches the preset reversing valve value, the reversing operation and the water removal operation are performed. In this way, the sensitivity of the reversing operation of the reversing mechanism 16 can be improved, avoiding the delivery of water to the distribution mechanism 20, and improving the content and purity of the output oil. The working principle and process of the first liquid level detector 41 are similar or identical to those of the first liquid level detector 41, and will not be elaborated on here.

[0141] Furthermore, the height of the preset reversing threshold can be set slightly lower than the heights of the first and second outlets. In this way, the multiphase flow splitting and processing device can maximize the use of the volume of the first tank 13 or the second tank 14, extend the reversing time of a single cycle, reduce the impact damage caused by reversing on the mixing mechanism 10, and extend the life and reliability of the mixing mechanism 10. Furthermore, the height of the preset reversing threshold can also be other heights, which are not limited here.

[0142] In other embodiments of the present application, the mixed transportation mechanism 10 also includes a third liquid level detector 43 arranged on the first tank body 13 and a fourth liquid level detector 44 arranged on the second tank body 14. The third liquid level detector 43 is used to detect the height of the oil-water interface in the first tank body 13 and control the connection and disconnection of the oil pipeline between the first tank body 13 and the distribution mechanism 20. The fourth liquid level detector 44 is used to detect the height of the oil-water interface in the second tank body 14 and control the connection and disconnection of the oil pipeline between the second tank body 14 and the distribution mechanism 20.

[0143] Specifically, the second output branch can also be directly connected to the oil pipeline. When the liquid mixture flows from the first processing mechanism 11 to the second processing mechanism 12, the fourth liquid level detector 44 is started and detected in real time. According to the above, that is, when the second tank body 14 is in the state of outputting gas and / or liquid, the fourth liquid level detector 44 detects the oil-water interface height in the second tank body 14. When the preset output threshold is reached, the valve group on the second output branch is opened, and the gas and / or liquid in the second tank body 14 is output to the distribution mechanism 20. When the preset reversing threshold is reached, the valve group on the second output branch is closed, and the gas and / or liquid in the second tank body 14 stops being output to the distribution mechanism 20. The working principle and process of the third liquid level detector 43 are similar or identical to those of the second liquid level detector 42, and will not be elaborated on here.

[0144] Furthermore, the preset output threshold height can be set slightly lower than the height of the circulation port. This can reduce the impact of the liquid mixture entering the tank on the output gas and / or liquid, thereby improving the quality of the output gas and / or liquid. Furthermore, the preset output threshold height can also be other heights, which are not limited here.

[0145] In other embodiments of the present application, the mixed transmission mechanism 10 also includes a first density detector 45 arranged on the first tank body 13 and a second density detector 46 arranged on the second tank body 14. The first density detector 45 is used to detect the gas density in the first tank body 13 and control the on-off of the gas pipeline between the first tank body 13 and the distribution mechanism 20. The second density detector 46 is used to detect the gas density in the second tank body 14 and control the on-off of the gas pipeline between the second tank body 14 and the distribution mechanism 20.

[0146] Specifically, the first output branch can also be directly connected to a gas pipeline. It is understood that a certain amount of gas, typically natural gas, is present in the crude oil mixture. As the liquid mixture flows from the first processing mechanism 11 to the second processing mechanism 12, the second density detector 46 is activated and performs real-time monitoring. The crude oil mixture within the second tank 14 continues to settle, with gas located in the upper portion of the second tank 14. As described above, when the second tank 14 is outputting gas, the second density detector 46 detects the gas density within the second tank 14. When the preset gas delivery threshold is reached, the valve assembly on the first output branch is opened, and the gas within the second tank 14 is output to the distribution mechanism 20. When the preset gas delivery stop threshold is reached, the valve assembly on the second output branch is closed, and the gas within the second tank 14 stops being output to the distribution mechanism 20. The operating principle and process of the first density detector 45 are similar or identical to those of the second density detector 46 and will not be elaborated upon here.

[0147] Furthermore, the preset gas delivery threshold can be set slightly lower than the height of the circulation port. This reduces the impact of the liquid mixture entering the tank on the output gas, improving the quality of the output gas. Furthermore, the preset gas delivery threshold can be set at other heights, which are not limited here. Furthermore, the gas delivery stop threshold can be set slightly lower than the heights of the first and second outlets. This maximizes gas output and improves the quality of the crude oil output during distribution.

[0148] like Figure 3 and Figure 4 As shown, in some other embodiments of the present application, the distribution mechanism 20 includes a first distribution mechanism 21 for distributing water, and the first distribution mechanism 21 is connected to the third tank 15 in the mixing mechanism 10.

[0149] Specifically, the first distribution mechanism 21 is connected to the third tank body 15 through a water distribution pipeline, and the separated water in the first tank body 13 is transported to the first distribution mechanism 21 along the water distribution pipeline. The first distribution mechanism 21 specifically processes the separated water output from the third tank body 15, which can simplify the process and achieve better treatment effect of the separated water.

[0150] In other embodiments of the present application, the first distribution mechanism 21 includes a fourth tank body 211 for purifying water, a fourth pipeline 212 connecting the third tank body 15 and the fourth tank body 211, and a fifth control valve 213 arranged on the fourth pipeline 212, and the fifth control valve 213 controls the conduction and closing of the fourth pipeline 212.

[0151] Specifically, when the first distribution mechanism 21 is provided with a fourth tank 211, the third tank 15 can be connected to the fourth tank 211 via the fourth pipeline 212. It is understood that either the water distribution pipeline or the fourth pipeline 212 can be used to connect the third tank 15 and the fourth tank 211. A fifth control valve 213 is provided on the fourth pipeline 212 to control the opening and closing of the fourth pipeline 212. When a preset reversing condition is met, the fifth control valve 213 controls the opening of the fourth pipeline 212, allowing the separated water to enter the fourth tank 211 via the fourth pipeline 212, where it is further purified within the fourth tank 211. This improves the purification quality of the separated water and reduces contamination of the discharge.

[0152] In other embodiments of the present application, the first distribution mechanism 21 further includes a water meter 214 for measuring the amount of purified water separated from the liquid mixture. The water meter 214 is connected to the water outlet 2111 of the fourth tank 211 .

[0153] Specifically, by setting up the water meter 214, the amount of water processed by the fourth tank body 211 can be detected in real time, the processing progress of the fourth tank body 211 can be understood, and the water content of the crude oil mixture can be calculated based on the detection results of the water meter 214, thereby improving the control and information level.

[0154] In other embodiments of the present application, the first distribution mechanism 21 further includes a water delivery pipeline 215 for outputting the purified water in the fourth tank 211 as remixing water and reinjection water.

[0155] Specifically, water delivery pipeline 215 is provided to transport the purified water from fourth tank 211 along water delivery pipeline 215 to a multiphase flow separation and processing device or oil well, thereby reducing the processing load at the oilfield's terminal oil and gas combined processing station. This system also transforms the remixing and reinjection water into a small circulation system, significantly reducing energy consumption and construction costs. This water separation process also improves the treatment efficiency of the remixing and reinjection water, reduces water consumption, and reduces crude oil production costs.

[0156] In other embodiments of the present application, the distribution mechanism 20 includes a second distribution mechanism 22 for distributing gas, and the second distribution mechanism 22 is connected to the first tank body 13 and the second tank body 14 in the first processing mechanism 11 and the second processing mechanism 12.

[0157] Specifically, through the second distribution mechanism 22, the gas after sedimentation and separation in the first tank body 13 or the second tank body 14 enters the second distribution mechanism 22 along the corresponding pipeline. The second distribution mechanism 22 further purifies the gas to improve the gas distribution level.

[0158] In other embodiments of the present application, the second distribution mechanism 22 includes a fifth tank body 221 for separating and purifying gas, a gas manifold 222 for transporting liquid-containing gas, and a gas distribution control valve 223 arranged on the gas manifold 222 to control the output of liquid-containing gas.

[0159] Specifically, when the second distribution mechanism 22 is provided with a fifth tank body 221, the fifth tank body 221 can optionally be provided with a gas manifold 222 to connect the first tank body 13 and the second tank body 14. The fifth tank body 221 can also optionally be provided with a first gas branch to connect the first tank body 13 and a second gas branch to connect the second tank body 14. The functions achieved by the two methods are the same and are not limited here. A gas distribution control valve 223 is provided on the gas distribution manifold 222, and the gas distribution control valve 223 controls the opening and closing of the gas distribution manifold 222. When the preset gas distribution threshold value is reached, the gas distribution control valve 223 controls the gas distribution manifold 222 to open, and the liquid-containing gas enters the fifth tank body 221 through the gas distribution manifold, and the liquid-containing gas is further purified and separated in the fifth tank body 221. In this way, the separation and purification level of the liquid-containing gas can be improved, and the gas purity can be improved.

[0160] In other embodiments of the present application, the inlet end of the gas supply manifold 222 is connected to the first tank body 13 and the second tank body 14, and the outlet end of the gas supply manifold 222 is connected to the fifth tank body 221; the gas distribution control valve 223 includes a first gas distribution valve 2231 for controlling the output of liquid gas in the first tank body 13 and a second gas distribution valve 2232 for controlling the output of liquid gas in the second tank body 14. The first gas distribution valve 2231 and the second gas distribution valve 2232 are two valve bodies of a three-way valve or two separately arranged control valves.

[0161] Specifically, by providing a three-way valve or two separately provided control valves, the gas transmission manifold 222 can be effectively controlled to improve the distribution efficiency.

[0162] In some other embodiments of the present application, the second distribution mechanism 22 further includes a gas meter 224 for measuring the gas separated from the liquid mixture, and the gas meter 224 is connected to the gas outlet 2211 of the fifth tank body 221 .

[0163] Specifically, when liquid-containing gas is output from the first tank 13 or the second tank 14 and transported along the gas manifold 222 to the fifth tank 221 for purification and separation, the fifth tank 221 then outputs the purified and separated gas through the gas outlet 2211. All gas output through the gas outlet 2211 passes through the gas meter 224 for volume measurement. This allows the volume of processed gas in the fifth tank 221 to be monitored, understanding the processing progress of the fifth tank 221. The gas content of the crude oil mixture can also be calculated based on the detection results of the gas meter 224, improving control and informationization capabilities.

[0164] In other embodiments of the present application, the second distribution mechanism 22 also includes a liquid return mechanism 225 for returning the liquid purified and separated by the fifth tank body 221 to the first treatment mechanism 11 and the second treatment mechanism 12. The liquid return mechanism 225 connects the fifth tank body 221 with the first tank body 13 or connects the fifth tank body 221 with the second tank body 14.

[0165] Specifically, after the liquid-containing gas input into the fifth tank 221 undergoes distribution processing, the gas and separated liquid are deposited within the fifth tank 221. This separated liquid is returned to the first tank 13 or the second tank 14 via the liquid return mechanism 225, re-entering the distribution cycle. This ensures that only gas is output from the second distribution mechanism 22, reducing pollutant emissions, maximizing separation of the crude oil mixture, and improving distribution efficiency.

[0166] In other embodiments of the present application, the liquid return mechanism 225 includes a liquid return manifold 2251 connected between the fifth tank body 221 and the first tank body 13 or between the fifth tank body 221 and the second tank body 14 and a first liquid return control valve 2252 arranged on the liquid return manifold 2251.

[0167] Specifically, the liquid return manifold 2251 is used to connect the fifth tank 221 with the first tank 13 and with the second tank 14. The first liquid return control valve 2252 on the fifth tank 221 is used to control the opening and closing of the liquid return manifold 2251. In this way, the opening and closing of the liquid return manifold 2251 can be controlled according to actual production conditions, thereby improving the control level.

[0168] In other embodiments of the present application, the second distribution mechanism 22 also includes a fifth liquid level detector 226 arranged on the fifth tank body 221 to detect the liquid level height in the fifth tank body 221, and the first return liquid control valve 2252 is controlled to be on and off according to the liquid height detected by the fifth liquid level detector 226.

[0169] In other embodiments of the present application, the liquid return mechanism 225 further includes a first liquid outlet valve 2253 arranged on the liquid return manifold 2251 and a second liquid return control valve 2254 that controls the connection and disconnection between the liquid return manifold 2251 and the first tank body 13 and the second tank body 14.

[0170] Specifically, the first liquid outlet valve 2253 is a control valve, and the second liquid return control valve 2254 can be two one-way valves. The one-way valves can be opened and closed according to the flow direction and pressure of the liquid in the liquid return manifold 2251, reducing the need for control valves and simplifying operation. Furthermore, when the second distribution mechanism 22 is equipped with the liquid return manifold 2251, the first liquid outlet valve 2253, and the second liquid return control valve 2254, the functions of the first gas branch pipe and the second gas branch pipe are consistent, so either one of the two can be provided to achieve the liquid return function of the second distribution mechanism 22. Furthermore, the second liquid return control valve 2254 can also be a three-way valve, etc., without limitation herein.

[0171] In other embodiments of the present application, the distribution mechanism 20 includes a third distribution mechanism 23 for distributing oil, and the third distribution mechanism 23 is connected to the first tank body 13 and the second tank body 14 in the first processing mechanism 11 and the second processing mechanism 12.

[0172] Specifically, through the third distribution mechanism 23, the third distribution mechanism 23 is connected to the first tank body 13 or the second tank body 14 through the output pipeline, and the first tank body 13 or the second tank body 14 is transported to the third distribution mechanism 23 along the output pipeline. The third distribution mechanism 23 specifically processes the output oil of the first tank body 13 or the second tank body 14, and can further process the oil that has been settled and separated in the first tank body 13 or the second tank body 14, thereby improving the oil distribution level.

[0173] In other embodiments of the present application, the third distribution mechanism 23 includes a sixth tank body 231 for separating and purifying oil, an oil manifold 232 for transporting low-water oil, and an oil distribution control valve 233 arranged on the oil manifold 232 to control the output of low-water oil.

[0174] Specifically, when the third distribution mechanism 23 is provided with a sixth tank body 231, the sixth tank body 231 can optionally be provided with an oil manifold 232 to connect with the first tank body 13 and the second tank body 14. The sixth tank body 231 can also optionally be provided with a first oil branch to connect with the first tank body 13 and a second oil branch to connect with the second tank body 14. The functions achieved by the two methods are the same and are not limited here. An oil distribution control valve 233 is provided on the oil distribution manifold 232, and the oil distribution control valve 233 controls the opening and closing of the oil distribution manifold 232. When the preset oil delivery threshold is reached, the oil distribution control valve 233 controls the oil distribution manifold 232 to open, and the low-water oil enters the sixth tank body 231 through the oil distribution manifold. The low-water oil is further purified and separated in the sixth tank body 231. In this way, the separation and purification level of the low-water oil can be improved, and the oil purity can be improved.

[0175] In other embodiments of the present application, the inlet end of the oil manifold 232 is connected to the first tank body 13 and the second tank body 14, and the outlet end of the oil manifold 232 is connected to the sixth tank body 231; the oil distribution control valve 233 includes a first oil distribution valve 2331 for controlling the output of low-water-content oil in the first tank body 13 and a second oil distribution valve 2332 for controlling the output of low-water-content oil in the second tank body 14. The first oil distribution valve 2331 and the second oil distribution valve 2332 are two valve bodies of a three-way valve or two separately arranged control valves.

[0176] Specifically, by providing a three-way valve or two separately provided control valves, the oil delivery manifold 232 can be effectively controlled to improve the distribution efficiency.

[0177] In other embodiments of the present application, the third distribution mechanism 23 further includes an oil meter 234 for measuring the amount of pure crude oil separated from the liquid mixture. The oil meter 234 is connected to the oil outlet 2311 of the sixth tank 231 .

[0178] Specifically, when low-water oil is output from the first or second tank 13, 14, it is transported along the oil manifold 232 to the sixth tank 231 for purification and separation. The sixth tank 231 then outputs the purified and separated crude oil through the oil outlet 2311. All crude oil output through the oil outlet 2311 passes through the oil meter 234, which measures the crude oil throughput. This allows monitoring the crude oil volume processed by the sixth tank 231, understanding its processing progress, and calculating the oil content of the crude oil mixture, thereby improving control and informationization capabilities.

[0179] In other embodiments of the present application, the third distribution mechanism 23 also includes a return water mechanism 235 for returning the water purified and separated by the sixth tank body 231 to the first treatment mechanism 11 and the second treatment mechanism 12. The return water mechanism 235 connects the sixth tank body 231 and the first tank body 13 or connects the sixth tank body 231 and the second tank body 14.

[0180] Specifically, after the low-water oil input to the sixth tank 231 undergoes distribution processing, crude oil and separated liquid are output and deposited in the sixth tank 231. This separated liquid is returned to the first tank 13 or the second tank 14 via the return mechanism 235, re-entering the distribution cycle. This ensures that only crude oil is output from the third distribution mechanism 23, reducing pollutant emissions, maximizing separation of the crude oil mixture, and improving distribution efficiency.

[0181] In other embodiments of the present application, the return water mechanism 235 includes a return water manifold 2351 connected between the sixth tank body 231 and the first tank body 13 or between the sixth tank body 231 and the second tank body 14 and a first return water control valve 2352 arranged on the return water manifold 2351.

[0182] Specifically, the return water manifold 2351 is used to connect the sixth tank 231 with the first tank 13 and the second tank 14. The first return control valve on the first return water tank is used to control the opening and closing of the return water manifold 2351. In this way, the opening and closing of the return water manifold 2351 can be controlled according to actual production conditions, thereby controlling whether water can flow through the return water manifold 2351, thereby improving the control level.

[0183] In other embodiments of the present application, the third distribution mechanism 23 also includes a sixth liquid level detector arranged on the sixth tank body 231 to detect the liquid level height in the sixth tank body 231, and the first return water control valve 2352 is controlled to be on and off according to the liquid height detected by the sixth liquid level detector.

[0184] In other embodiments of the present application, the return water mechanism 235 further includes a second liquid outlet valve 2353 arranged on the return water manifold 2351 and a second return water control valve 2354 that controls the connection and disconnection between the return water manifold 2351 and the first tank body 13 and the second tank body 14.

[0185] Specifically, the second liquid outlet valve 2353 is a control valve, and the second return water control valve 2354 can be two one-way valves. The one-way valves can be opened and closed according to the flow direction and pressure of the liquid in the return water manifold 2351, reducing the need for control valves and simplifying operation. Furthermore, when the third distribution mechanism 23 is equipped with a return oil manifold, a second liquid outlet valve 2353, and a second return water control valve 2354, the functions of the first oil branch pipe and the second oil branch pipe are consistent, so either one of the two can be provided to achieve the return water function of the third distribution mechanism 23. Furthermore, the second return water control valve 2354 can also be a three-way valve, etc., without limitation herein.

[0186] In other embodiments of the present application, the third distribution mechanism 23 further includes a gas pipeline connected to the gas outlet of the sixth tank 231 and a gas control valve arranged on the gas pipeline to control the output of the gas in the sixth tank 231.

[0187] Specifically, the low-water oil in the sixth tank body 231 is separated into gas through sedimentation, and the gas pipeline is used to output the gas separated by sedimentation. The gas supply control valve is used to control the opening and closing of the gas pipeline, thereby realizing whether the output gas can flow through the gas pipeline, thereby realizing controllable gas supply.

[0188] like Figures 1 to 4 As shown, in some other embodiments of the present application, bypass lines are further provided on the input and output pipeline groups, each equipped with a bypass check valve. If a malfunction occurs in the mixing mechanism 10, the crude oil mixture is prevented from entering the mixing mechanism 10 through the input pipeline group, resulting in a reduced input volume or even no crude oil mixture entering the mixing mechanism 10. To prevent damage to the mixing mechanism 10 due to excessive pipeline pressure, the crude oil mixture can be directly fed into the output pipeline group via the bypass line valve.

[0189] It is understandable that when the mixing mechanism 10 is operating normally, the bypass pipeline does not allow any substance to pass through, or only a small amount of crude oil mixture to pass through, due to the action of the bypass one-way valve; when the mixing mechanism 10 is operating abnormally, the bypass one-way valve allows all or most of the crude oil mixture flowing in through the input pipeline group to pass through the bypass pipeline to protect the mixing mechanism 10.

[0190] The above is a detailed introduction to a multiphase flow distribution and processing device provided in an embodiment of the present application. Specific examples are used herein to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core idea. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
