Description

Technical Field

[0001] This invention relates to the field of petroleum extraction equipment technology, specifically to an oil and gas transportation and pressurization device. Background Technology

[0002] In the extraction and transportation of resources such as oil, natural gas, chemicals, and coalbed methane, the mixing and transportation of multiphase fluids such as oil, water, and gas are often involved. Traditional transportation equipment, such as centrifugal pumps and screw pumps, can achieve the function of transporting multiphase media to a certain extent, but they are prone to problems such as flow fluctuations, air locks, and efficiency reduction under complex working conditions. Moreover, they are not very adaptable to changes in the proportion of each phase. In addition, traditional booster and metering equipment are mostly independent devices, which are large in size, have high energy consumption, and have outdated control methods, making it difficult to meet the modern industrial needs of intelligent, integrated, and high-precision metering.

[0003] A search revealed that prior art publication number CN 105508206 A discloses a booster pump, including a drive device, a first booster pump body, and a second booster pump body. The drive device has a first end and a second end along its axial direction. The first booster pump body is installed at the first end of the drive device and is drivenly connected to the drive device. The second booster pump body is installed at the second end of the drive device and is drivenly connected to the drive device. This booster pump, utilizing a dual-pump structure, has a large flow rate, low vibration and noise, and low cost.

[0004] Therefore, based on the above search and combined with existing technologies, most existing gas-liquid separation devices rely on static cyclone to achieve preliminary gas-liquid separation. They lack auxiliary structures coupled with the flow state, making it difficult to fully utilize the cyclone energy of crude oil to treat impurities. This results in larger particulate impurities easily clogging in subsequent pipelines or filtration units, affecting the stable operation of the system. On the other hand, traditional filtration structures are mostly one-time interception devices, which cannot dynamically reduce or break down particulate impurities. They have high filtration loads and require frequent shutdowns for cleaning or replacement after a period of operation, resulting in low efficiency. Therefore, this application proposes an oil and gas transportation booster device. Summary of the Invention

[0005] The purpose of this invention is to provide an oil and gas transportation booster device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an oil and gas transportation and boosting device, comprising a separation cylinder, a support cylinder fixedly connected to the bottom end of the separation cylinder, the support cylinder and the separation cylinder together constituting an integrated multiphase booster pump body with cyclone separation and transportation functions, an inlet pipe fixedly connected to the outer surface of the separation cylinder for introducing an oil-gas mixture, a cyclone separation device provided inside the separation cylinder for separating gas and liquid, an outlet pipe fixedly connected to the outer surface of the separation cylinder for outputting the gas portion after cyclone separation, an oil outlet pipe fixedly connected to the bottom end of the support cylinder for transporting the separated liquid phase portion, an isolation cylinder fixedly connected to the inner end of the support cylinder, two filter cylinders detachably connected to the upper end of the oil outlet pipe, two slag discharge pipes fixedly connected to the outer surface of the isolation cylinder, and the slag discharge pipes fixedly connected to the filter cylinders.

[0007] As a further embodiment of the present invention, the separation device includes a separation sleeve, which is fixedly connected to the inner end of the separation cylinder, and the separation sleeve divides the upper inner side of the separation cylinder into two chambers. The oil-gas mixture enters the chamber on the left side of the separation sleeve from the inlet pipe. A drive motor is fixedly connected to the upper end of the separation cylinder, and a drive rod is passed through the inner end of the separation sleeve. The upper end of the drive rod is fixedly connected to the output end of the drive motor.

[0008] As a further embodiment of the present invention, a return pipe is fixedly connected to the end of the separation sleeve away from the drive motor. The return pipe is sleeved outside the drive rod. A turbine blade is rotatably mounted on the end of the return pipe away from the separation sleeve, and an agitator is fixedly connected to the outer surface of the turbine blade. The bottom end of the drive rod is fixedly connected to the turbine blade. A guide groove for gas flow is opened at the inner end of the turbine blade. This structural design realizes efficient separation and guidance of the oil-gas mixture. The rotation of the agitator can effectively break up oil bubbles and promote gas-liquid separation. At the same time, the design of the guide groove ensures the smooth discharge of the separated gas, significantly improving the separation efficiency and reducing energy consumption.

[0009] As a further aspect of the present invention, the left chamber of the separating sleeve is provided with a liquid inlet, which communicates with the interior of the separating cylinder, and the right chamber of the separating sleeve is provided with an air outlet, which communicates with the return pipe. A conical bucket is fixedly connected to the end of the separating cylinder furthest from the drive motor. This conical structure design effectively promotes fluid flow after gas-liquid separation. The liquid inlet adopts a gradually expanding flow channel design to reduce fluid resistance, and the gas outlet is equipped with anti-vortex guide vanes to ensure smooth exhaust. The tilt angle of the conical bucket is optimized to achieve efficient collection and discharge of the separated medium. The entire system achieves continuous and efficient separation of the oil-gas mixture.

[0010] As a further embodiment of the present invention, a sealing tube is rotatably installed at the inner end of the isolation cylinder, and a passive ring is fixedly connected to the upper end of the sealing tube. The passive ring passes through the inside of the conical bucket, and the crude oil forms a vortex motion under the rotation of the turbine blades, thereby driving the passive ring to rotate.

[0011] As a further embodiment of the present invention, two oil-grinding shells are fixedly installed on the outer surface of the sealing tube. These two oil-grinding shells are located inside the isolation cylinder. A guide ring is fixedly installed at the inner end of the isolation cylinder, and the guide ring is fitted onto the outer surface of the sealing tube, forming a clearance fit. This double oil-grinding shell and guide ring structure design effectively enhances the centrifugal separation effect of crude oil. Through the rotational compression of the oil-grinding shells and the guiding effect of the guide ring, the impurity separation efficiency is significantly improved, while ensuring the smooth flow of crude oil and reducing equipment operating resistance.

[0012] As a further embodiment of the present invention, a rotating rod is provided through the inner end of the oil grinding shell, and irregular blocks are fixedly connected to both the upper and lower ends of the rotating rod. A plurality of rectangular holes are opened on the outer surface of the oil grinding shell, and a striking block is provided in each of the rectangular holes. A passive plate is rotatably installed on the outer surface of the striking block, and the passive plate is located inside the oil grinding shell.

[0013] As a further embodiment of the present invention, an oil seepage pipe is fixedly connected to the inner bottom end of the support cylinder, the oil seepage pipe is connected to the oil outlet pipe, a central pipe is inserted through the inner end of the slag discharge pipe, a sealing pipe is fixedly installed at the inner end of the slag discharge pipe, and the central pipe is inserted inside the sealing pipe, and multiple guide plates are rotatably installed on the outer surface of the central pipe.

[0014] As a further embodiment of the present invention, the guide plate is arranged in a ring shape, the outer surface of the central tube is wrapped with a sealing bladder, the inner end of the central tube is provided with a threaded rod, the outer surface of the threaded rod is threaded with a movable plug, and the central tube and the sealing bladder are connected through a connecting pipe. This innovative structure controls the expansion state of the sealing bladder by the axial displacement of the movable plug, which not only achieves dynamic sealing at the pipe connection, but also adapts to the installation requirements of different pipe diameters, significantly improving the sealing reliability and working condition adaptability of the equipment.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. When this invention is used, the passive ring and sealing pipe are rotated by the flow of crude oil. Combined with the cooperation of the guide ring and the crushing block, the pretreatment of larger particulate impurities in crude oil is achieved. Under the action of vortex flow, the impurities generate continuous friction with the outer surface of the crushing block above the guide ring. The dynamic reduction of impurity particles can be achieved without affecting the flow efficiency, thereby effectively reducing the risk of clogging of the subsequent filtration device. 2. The present invention is equipped with an oil crushing shell, a gear mechanism and a striking structure. The striking block is driven by gear transmission to reciprocate and crush large particles of impurities remaining inside the isolation cylinder, thereby improving the transportability of impurities, ensuring stable system operation and extending the service life of the filter components. 3. In this invention, the filter cartridge adopts an unlockable and detachable structural design. With the radial expansion of the sealing bladder in the sealing tube, the slag discharge channel can be reliably cut off. The filter cartridge can be disassembled and replaced without stopping the machine, which significantly improves maintenance efficiency. It is suitable for continuous mining or high-load operation environments and effectively avoids resource waste and production capacity reduction caused by machine stoppage for replacement. 4. After the oil-gas mixture enters the separator through the liquid inlet pipe, a strong swirling flow field is formed under the high-speed rotation of the turbine blades. The gas-liquid density difference is used to achieve rapid separation. The gas is efficiently discharged through the return pipe and the outlet pipe, which significantly improves the separation efficiency. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1: Please refer to Figures 1-3 An oil and gas conveying booster device includes a separation cylinder 1. The bottom end of the separation cylinder 1 is fixedly connected to a support cylinder 5 by bolts. The support cylinder 5 and the separation cylinder 1 together constitute an integrated multiphase booster pump body with cyclone separation and conveying functions. A support frame is fixedly installed on the outer surface of the support cylinder 5. The bottom end of the support frame is fixed to the ground by bolts to provide stable support for the pump body. An inlet pipe 3 is fixedly connected to the outer surface of the separation cylinder 1 for introducing an oil-gas mixture. The oil-gas mixture flows into the interior of the separation cylinder 1 through the inlet pipe 3. A cyclone separation device is provided inside the separation cylinder 1 for separating gas and liquid. An outlet pipe 6 is fixedly connected to the outer surface of the separation cylinder 1 for outputting the gas portion after cyclone separation. An oil outlet pipe 4 is fixedly connected to the bottom end of the support cylinder 5 for conveying the separated liquid phase portion. An isolation cylinder 402 is fixedly connected to the inner end of the support cylinder 5. The upper end of the oil outlet pipe 4 is detachably connected to two filter cylinders 101. The filter cylinders 101 are located on the left and right sides of the support cylinder 5, and each filter cylinder 101 is equipped with a filter screen to intercept larger particulate impurities in the crude oil. The outer surface of the isolation cylinder 402 is fixedly connected to two slag discharge pipes 301, and the slag discharge pipes 301 are fixedly connected to the filter cylinders 101 by bolts.

[0020] like Figures 2-4As shown, the separation device includes a separation sleeve 201, which is fixedly connected to the inner end of the separation cylinder 1. The separation sleeve 201 divides the upper inner side of the separation cylinder 1 into two chambers. The oil-gas mixture enters the left chamber of the separation sleeve 201 from the liquid inlet pipe 3. The upper end of the separation cylinder 1 is fixedly connected to the drive motor 2 by bolts. The inner end of the separation sleeve 201 is provided with a drive rod 203. The upper end of the drive rod 203 is fixedly connected to the output end of the drive motor 2. Specifically, the diameter of the drive rod 203 is smaller than the inner diameter of the separation sleeve 201. The drive rod 203 and the separation sleeve 201 are connected by a sealed bearing, which is located at the upper inner side of the separation sleeve 201. A return pipe 204 is fixedly connected to the end of the separating sleeve 201 away from the drive motor 2. The return pipe 204 is sleeved outside the drive rod 203 and does not contact the outer surface of the drive rod 203. A turbine blade 205 is rotatably installed at the end of the return pipe 204 away from the separating sleeve 201. A stirring blade 206 is fixedly welded to the outer surface of the turbine blade 205. The bottom end of the drive rod 203 is fixedly connected to the turbine blade 205. A guide groove 207 that allows gas to flow is opened at the inner end of the turbine blade 205.

[0021] Example 2: Please refer to Figure 3 , Figure 4 As shown, an oil and gas conveying pressurization device, based on embodiment 1, has a liquid inlet 209 in the left chamber of the separating sleeve 201, which is connected to the interior of the separating cylinder 1, and an air outlet 208 in the right chamber of the separating sleeve 201, which is connected to the return pipe 204. A conical bucket 202 is fixedly welded to the end of the separating cylinder 1 away from the drive motor 2. After the oil-gas mixture flows into the separator cylinder 1 through the inlet pipe 3, it is driven by the turbine blades 205 to rotate the stirring blades 206, forming a rotating flow field inside the separator cylinder 1 to achieve preliminary gas-liquid separation. Due to the significant density difference between the oil and the gas, the forces exerted on different phases by the oil-liquid mixture during centrifugal rotation are also different. Under the action of centrifugal force, the crude oil quickly moves towards the inner wall of the separator cylinder 1 and flows along the inner wall of the separator cylinder 1 into the conical bucket 202, while the gas is subjected to a smaller centrifugal force, concentrates near the central axis of the separator cylinder 1, and flows upward along the central axis, eventually passing through the inside of the turbine blades 205 and flowing out from the outlet 208 through the return pipe 204. The stirring blade 206 is twisted, which further enhances the swirling intensity and improves the gas-liquid separation efficiency when the turbine blade 205 rotates.

[0022] like Figures 5-7As shown, a sealing tube 302 is rotatably installed at the inner end of the isolation cylinder 402. A passive ring 401 is fixedly welded to the upper end of the sealing tube 302, and the passive ring 401 passes through the inside of the conical bucket 202. The crude oil forms a vortex motion under the rotation of the turbine blades 205, thereby driving the passive ring 401 to rotate. Two oil milling shells 404 are fixedly installed on the outer surface of the sealing tube 302. The two oil milling shells 404 are located inside the isolation cylinder 402, and the two oil milling shells 404 are respectively corresponding to the two slag discharge pipes 301. A flow guide ring 405 is fixedly installed at the inner end of the isolation cylinder 402, and the flow guide ring 405 is sleeved on the outer surface of the sealing tube 302. The outer surface of the guide ring 405 has multiple rectangular holes arranged in a ring, and the inner end of each rectangular hole is rotatably mounted with a crushing block 406 via a rotating shaft. Specifically, the outer surface of the crushing block 406 is fixedly welded with a protrusion. The outer surface of the passive ring 401 has multiple rectangular strip holes, which connect to the upper chamber of the guide ring 405. Impurities in the crude oil enter the upper part of the guide ring 405 through these rectangular strip holes. It is worth noting that the diameter of the rectangular strip holes is larger than the volume of any crude oil impurity, so no blockage will occur during operation. When impurities move above the guide ring 405, the rotating passive ring 401 drives the impurities to move through the crude oil. The impurities come into contact with and rub against the protrusions on the surface of the crushed block 406, gradually breaking down and shrinking. At the same time, it pushes the crushed block 406 to rotate, and finally flows with the crude oil below the guide ring 405.

[0023] like Figure 5 , Figure 7 , Figure 8 As shown, to optimize the smooth movement of the oil milling casing 404, a rotating ring 408 is fixedly installed at the bottom inner side of the sealing tube 302. A passive impeller 407 is welded to the upper end of the rotating ring 408. When the crude oil forms a vortex flow, it drives the passive impeller 407 to rotate, thereby enhancing the motion force of the oil milling casing 404. A rotating rod 413 is inserted through the inner end of the oil milling casing 404. Both the upper and lower ends of the rotating rod 413 are fixedly connected to irregularly shaped blocks 412. The irregularly shaped blocks 412 are elliptical and are used for oil milling. Multiple rectangular holes are provided on the outer surface of the shell 404. A striking block 409 is inserted into each rectangular hole. A passive plate 410 is rotatably mounted on the outer surface of the striking block 409. The passive plate 410 is located inside the oil mill shell 404. Specifically, the passive plate 410 corresponds to the irregular block 412. When the irregular block 412 rotates, the protruding part of its outer surface contacts the outer surface of the passive plate 410 and pushes the striking block 409 to move away from the oil mill shell 404 through the passive plate 410. More specifically, the passive plate 410 and the oil milling shell 404 are connected by a return spring 411, so that after the passive plate 410 moves, it returns to its initial state under the elastic force of the return spring 411. It is worth noting that the outer surface of the oil milling shell 404 does not contact the inner wall of the isolation cylinder 402. Therefore, the striking block 409 can move towards the outside of the oil milling shell 404. When the oil milling shell 404 rotates around the outside of the sealing pipe 302, the striking block 409 also moves back and forth continuously, thereby further breaking up the impurities in the crude oil and preventing the pipeline from being blocked during subsequent flow.

[0024] An oil seepage pipe 403 is fixedly connected to the bottom inner side of the support cylinder 5. Multiple oil seepage holes are evenly opened on the outer surface of the oil seepage pipe 403. The high-pressure crude oil inside the sealing pipe 302 continuously seeps into the inner cavity of the oil seepage pipe 403 through the oil seepage holes. The oil seepage hole at the upper end of the oil seepage pipe 403 is located inside the isolation cylinder 402. A toothed ring 415 is fixedly installed on the outer surface of the oil seepage pipe 403. A driven gear 414 is fixedly sleeved on the outer surface of the rotating rod 413. The driven gear 414 meshes with the toothed ring 415. The oil seepage pipe 403 is connected to the oil outlet pipe 4.

[0025] like Figure 2 , Figures 9-11 As shown, a central tube 303 passes through the inner end of the slag discharge pipe 301. The central tube 303 and the slag discharge pipe 301 are connected by a support frame. A sealing pipe 302 is fixedly installed at the inner end of the slag discharge pipe 301, and the central tube 303 passes through the interior of the sealing pipe 302. Multiple guide plates 307 are rotatably installed on the outer surface of the central tube 303 via a rotating shaft. The guide plates 307 are arranged in a ring. A sealing bladder 308 is wrapped around the outer surface of the central tube 303. When the sealing bladder 308 expands, it supports the guide plates 307 and makes them rotate. It is worth noting that when the guide plates 307 are fully open, they do not contact the inner wall of the sealing pipe 302. The outer surface of the sealing bladder 308 is fixedly connected to the inner wall of the guide plates 307. After the sealing bladder 308 is fully expanded, it contacts the inner wall of the sealing pipe 302. Specifically, a threaded rod 309 is inserted through the inner end of the central tube 303, and a movable plug 306 is threadedly fitted on the outer surface of the threaded rod 309. The outer surface of the movable plug 306 is tightly fitted with the inner wall of the central tube 303, and a rectangular groove is opened on the outer surface of the movable plug 306. A rectangular strip is fixedly installed on the inner end of the central tube 303, and the rectangular strip passes through the rectangular groove, so that when the threaded rod 309 rotates, it drives the movable plug 306 to move without causing it to rotate on its own. The central tube 303 and the sealing bladder 308 are connected through a guide tube.

[0026] A central rod 304 is rotatably connected to the end of the central tube 303 away from the guide plate 307. The central rod 304 is fixedly connected to the threaded rod 309. An unlocking rod 305 is provided on the upper inner side of the filter cylinder 101. A rotating handle is fixedly connected to the end of the unlocking rod 305 away from the slag discharge pipe 301 by bolts, making it easier for the operator to rotate the unlocking rod 305. It should be noted that a shut-off valve is installed at the connection between the oil outlet pipe 4 and the filter cylinder 101. This valve can be closed before disassembling the filter cylinder 101 to effectively block the pipeline connection, thereby completely preventing the risk of leakage of residual crude oil in the oil outlet pipe 4. The adjacent ends of the unlocking rod 305 and the center rod 304 are fixedly connected to the male and female locking blocks. The two sets of locking blocks mesh with each other. When the unlocking rod 305 rotates, it directly drives the center rod 304 to rotate synchronously through the meshing transmission of the locking blocks. The connection method is not limited to male and female locking blocks, but can also be a ratchet meshing device, etc.

[0027] The working principle of this invention is: In use, the oil-gas mixture enters the interior of the separator 1 through the liquid inlet pipe 3. The output end of the drive motor 2 drives the drive rod 203 to rotate. At the same time, the drive rod 203 rotates and drives the turbine blades 205 to rotate, causing the oil-gas mixture to vortex flow in the separator 1. The gas part passes through the interior of the turbine blades 205 and flows along the interior of the return pipe 204, and flows out from the outlet 208. Then it flows into the outlet pipe 6, and then the outlet pipe 6 delivers the gas to the next device. The vortex-flowing crude oil drives the passive ring 401 and sealing pipe 302 to rotate. At the same time, it is pressurized by the turbine blades 205, causing impurities in the crude oil to enter the guide ring 405 through the rectangular slots of the passive ring 401. Under the force of the vortex-flowing crude oil, the impurities move above the guide ring 405 and gradually become smaller after rubbing against the outer surface of the crushing block 406. Then, they flow to the bottom of the guide ring 405. At this time, the oil mill shell 404 rotates during the rotation. The passive gear 414 rotates under the action of meshing with the gear ring 415, which drives the rotating rod 413 to rotate. The rotating rod 413 pushes the passive plate 410 to move through the shaped block 412, causing the striking block 409 to move. Then, the striking block 409 returns to its initial state under the elastic force of the return spring 411, so as to further crush the impurities in the crude oil inside the isolation cylinder 402 and prevent the pipeline from being blocked during the flow. Subsequently, the crude oil flows through the seepage pipe 403 and into the oil outlet pipe 4. Since the crude oil inside the oil outlet pipe 4 is constantly flowing, the crude oil containing impurities inside the filter cartridge 101 is filtered and then flows back into the oil outlet pipe 4. When impurities accumulate excessively inside one of the filter cylinders 101, the unlocking rod 305 is rotated by turning the handle. The unlocking rod 305 then rotates the central rod 304. As the central rod 304 rotates, it moves the movable plug 306 via the threaded rod 309. The movable plug 306 compresses the air inside the central tube 303, causing the sealing bladder 308 to expand. Subsequently, the outer surface of the expanded sealing bladder 308 contacts the inner wall of the sealing tube 302, thereby cutting off the flow of liquid inside the slag discharge pipe 301. Then, the valves of the filter cylinder 101 and the oil outlet pipe 4 are gradually closed. The fixing bolts between the filter cylinder 101, the slag discharge pipe 301, and the oil outlet pipe 4 are then removed, and the filter cylinder 101 is replaced. At this point, the unlocking rod 305 engages with the central rod 304, thus enabling the replacement of the filter equipment without stopping the machine and ensuring continuous mining operations.
