Abstract
Description
Technical Field
[0001] The present application relates to the technical field of oil production engineering, and in particular to a downhole production dynamic measurement and adjustment device. Background Art
[0002] Faced with the two major problems of interlayer contradiction and plane contradiction that are common in the high water content stage of oil fields, stratified oil production technology can achieve effective development of medium and low permeability reservoirs, reduce ineffective water circulation, and ultimately improve recovery. With the long-term exploitation of oil fields, the imbalance of oil field production profiles has become increasingly severe. For this reason, major oil fields have begun to use stratified water injection technology to improve interlayer contradictions, that is, injecting water into each layer of oil reservoirs in the well to make up for the underground deficit caused by crude oil production, so as to maintain or increase the reservoir pressure and achieve high and stable production of oil fields. Stratified water injection technology often involves inserting a packer into the water injection well to separate the reservoir layers with large differences, and then using a water distributor to distribute water in layers, so that the water injection volume of the high permeability layer is controlled, the water injection of the medium and low permeability reservoir layer is strengthened, and all types of reservoir layers can play a role.
[0003] Among them, the water distributor is one of the key tools in the stratified water injection project, but the water distributors in the prior art are all single-layer controlled, that is, each water distributor corresponds to managing an oil reservoir layer sealed by the packer. When it is necessary to control multi-layer oil reservoirs, it is necessary to set up multiple water distributors accordingly, and it is also necessary to connect each water distributor through cables between layers to realize energy supply and communication, which makes the underground structure complicated, the cost is high, and the construction is difficult.
[0004] In addition, due to the heterogeneity and permeability differences of the oil reservoir, and with the long-term exploitation of the oil field, the effect of stratified water injection has gradually deteriorated. There are often a series of problems such as water appearing too early in the high permeability layer, poor utilization of the low permeability reservoir, gradually increasing differences in pressure and water absorption capacity of each layer, and further aggravation of interlayer interference. This puts higher demands on the flow regulation function of water injection or oil production tools, while the stratified flow regulation function of the water distributor in the prior art is often poor and difficult to meet the demand.

[0036] In order to make the technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0037] like Figures 1 to 13 As shown, the present invention provides a downhole production dynamic measurement and adjustment device, comprising a flow regulating module 1, a flow monitoring module 2, at least one screening module 3 and a flow diversion module 4 connected in sequence;
[0038] The flow regulating module 1 is wrapped with a shell 101 on the outside, and a circuit installation cylinder 11 and at least two flow regulating devices 12 are arranged inside the shell 101; the middle of the circuit installation cylinder 11 has a central through hole 114, and the flow regulating device 12 is arranged at the bottom of the circuit installation cylinder 11 and located outside the central through hole 114;
[0039] The flow monitoring module 2 and the screening module 3 each have at least two peripheral pipes, and the peripheral pipes of the two are correspondingly connected; the upper pipe openings of the peripheral pipes of the flow monitoring module 2 are respectively arranged corresponding to the flow regulating devices 12, and each peripheral pipe is respectively provided with a flow monitoring device 213; the bottom of one of the peripheral pipes of the screening module 3 is blocked, and a sieve hole 301 is provided on the pipe wall of the peripheral pipe;
[0040] The diversion module 4 has at least one peripheral pipe 411 , a first end of which is connected to an unblocked peripheral pipe at the bottom of the screening module 3 , and a second end thereof is connected to the underground as a liquid flow port.
[0041] In the technical solution of the present invention, the above-mentioned downhole production dynamic measurement and adjustment device is placed in the wellbore of the oil well. By connecting and cooperating with conventional oil pipes and isolation devices, it can be used for stratified water injection (that is, injecting water into the water from top to bottom in layers), and can also be used for stratified oil production (that is, producing oil in different reservoir layers from bottom to top). For example, when injecting water in layers downward, water can be injected from the central through hole 114 of the circuit installation tube 11 into the space surrounded by the shell 101 below the circuit installation tube 11 (at this time, the flow regulating device 12 can be immersed in water), and the water flow into the corresponding peripheral pipes in the flow monitoring module 2 is controlled by each flow regulating device 12. At the same time, the flow monitoring device 213 on each peripheral pipe of the flow monitoring module 2 can also monitor the flow size in the peripheral pipe in real time, so as to realize flow regulation and parameter monitoring of multiple layers of oil reservoirs; when water flows along the peripheral When the pipeline flows into the peripheral pipeline blocked at the bottom of the screening module 3, because its bottom is blocked and its side wall is provided with sieve holes, water can only flow out from the sieve holes of its side wall, thereby realizing the water injection operation of the first layer of the reservoir at the screening module 3, and by setting it in the form of sieve holes, it can prevent impurities in the formation from entering the measuring and adjusting device and causing blockage or damage; at the same time, the water flow entering the other peripheral pipelines of the screening module 3 can continue to flow downward into the peripheral pipeline 411 of the diversion module 4, and then flow into other reservoir layers through the second end of the peripheral pipeline 411. When performing stratified oil production, the principle is the same as stratified water injection, by pumping oil upward, but the direction of the liquid flow is opposite, which will not be repeated here.
[0042] It can be seen from this that by only using the above-mentioned downhole production dynamic measurement and adjustment device provided in the present application, it is possible to manage at least two layers of oil reservoirs, greatly reducing the cost and construction difficulty; further, it is also possible to simultaneously achieve flow regulation and parameter monitoring of multiple layers of oil reservoirs, which has positive significance and an important role in realizing intelligent stratified mining, efficient water control and oil increase, and improving oil reservoir recovery.
[0043] In the technical solution of the present invention, a variety of implementation methods can be used to implement the above-mentioned downhole production dynamic measurement and adjustment device. The technical solution of the present invention will be described in detail below by taking several implementation methods as examples.
[0044] For example, preferably, in a specific embodiment of the present invention, Figure 3 As shown, the circuit mounting tube 11 may include: a first connector 111, a circuit mounting board 112 and a second connector 113; the first connector 111 is located at the top of the circuit mounting board 112, the second connector 113 is located at the bottom of the circuit mounting board 112, and the second connector 113 is sealedly connected to the housing 101; the middle of the first connector 111, the circuit mounting board 112 and the second connector 113 has a through center hole 114.
[0045] Through the above-mentioned arrangement, the center through hole 114 can be connected to the upper pipeline by using the first joint, so that water can be injected into the lower part or oil can be pumped to the ground; by setting up a circuit mounting board, the circuit or communication module can be set on the circuit mounting board, and the second joint can be set up, on the one hand, to achieve connection with the flow regulating device 12, and on the other hand, due to the sealed connection between the second joint 113 and the shell 101, the circuit installed on the circuit mounting board 112 can be isolated, so that the liquid flows from the center through hole 114 to the part below the second joint, thereby preventing the liquid from entering the circuit, thereby playing a role in isolating and protecting the circuit.
[0046] For another example, preferably, in a specific embodiment of the present invention, Figure 4 and Figure 5 As shown, the flow regulating device 12 may include: a driving device and a conical plugging head 123, one end of the driving device is arranged at the bottom of the circuit installation tube 11, and the other end thereof is provided with a conical plugging head, and the driving device is used to drive the conical plugging head 123 to move up and down.
[0047] In the technical solution of the present invention, a driving device is used to drive the conical plugging head 123 to move up and down. Since the upper pipe openings of each peripheral pipe of the flow monitoring module 2 are respectively arranged corresponding to each flow regulating device 12, when the driving device drives the conical plugging head to move downward, the conical plugging head can be partially or completely covered at the upper pipe openings of the peripheral pipes of the flow monitoring module 2, thereby realizing the opening and closing degree of the upper pipe openings of the peripheral pipes of the flow monitoring module 2, and then realizing flow control, and can realize individual control of each peripheral pipe.
[0048] By setting the bottom surface of the plugging head to a conical surface, compared with a plugging head with a flat bottom, not only can the surrounding pipelines be fully opened or closed, but the flow rate can also be controlled; in addition, the conical plugging head can be used to achieve the slow closing or opening of the upper pipe mouth of the surrounding pipeline of the flow monitoring module 2, rather than directly fully opening or closing it, thereby preventing the sudden increase or decrease of the liquid pressure at the plugging head, which is beneficial to the stability and reliability of the measurement and adjustment device.
[0049] Preferably, as an example, in a specific embodiment of the present invention, Figure 5 As shown, the driving device may include: a motor 124, a reducer 121 and a screw 122; wherein, the output end of the motor 124 is connected to the input end of the reducer 121, the reducer 121 is used to reduce the speed of the motor, the output end of the reducer 121 is connected to one end of the screw 122, and a conical plugging head 123 is installed at the other end of the screw, and the screw 122 is used to convert the rotation into linear movement, thereby realizing the up and down movement of the conical plugging head.
[0050] In addition, as an example, in a preferred embodiment of the present invention, Figures 6 to 11 As shown, the flow monitoring module 2, the screening module 3 and the diversion module 4 may have a central pipeline in the middle that is interconnected. By setting up the central pipeline, on the one hand, the monitoring equipment can be lowered through the central through hole 114 on the circuit installation cylinder 11 and the above-mentioned central pipeline, providing a channel for underground data monitoring; on the other hand, when the oil body is pumped into the space between the circuit installation cylinder 11 and the flow monitoring module 2 during oil production, since the central pipeline is set in the middle of the flow monitoring module 2, the solid impurities mixed in the oil body can fall back at the central pipeline of the flow monitoring module 2, preventing excessive accumulation in the space between the circuit installation cylinder 11 and the flow monitoring module 2 and affecting the normal operation of the flow regulating device 12.
[0051] Preferably, as an example, in a specific embodiment of the present invention, Figure 6 and Figure 7 As shown, the peripheral pipe 211 of the flow monitoring module 2 is located outside the central pipe 212, and the lower pipe opening of the peripheral pipe 211 of the flow monitoring module 2 is waist-shaped, which can increase the cross-sectional area of the pipe opening compared to a circular pipe opening to ensure smooth liquid flow.
[0052] In addition, as an example, in a preferred embodiment of the present invention, Figure 1 , Figure 8 and Fig. 9 As shown, the screening module 3 comprises: a central pipe 311, an outer pipe wall 302 and at least two side plates 312;
[0053] The outer tube wall 302 is sleeved on the outside of the central pipe 311, and an annular space is formed between the outer tube wall 302 and the central pipe 311. At least two side plates are arranged between the outer tube wall 302 and the central pipe 311 to divide the annular space into at least two peripheral pipes with fan-shaped cross-sections. The bottom of one of the peripheral channels is blocked, and a plurality of sieve holes 301 are arranged on the outer tube wall 302 corresponding to the peripheral pipe, so that the liquid (water or oil) in one of the peripheral pipes can flow out or flow in from the sieve holes.
[0054] Of course, in the technical solution of the present invention, the peripheral pipe of the screening module 3 may also be other structural forms that can achieve the above functions.
[0055] In addition, as an example, in a preferred embodiment of the present invention, Fig. 9 and Fig.10As shown, the first end of the peripheral pipe 411 of the diversion module 4 is connected to the peripheral pipe of the screening module, and the pipe mouth cross-section can be a waist-shaped cross-section, so as to increase the cross-sectional area of the pipe mouth, and its second end can be set as a horizontal liquid flow port 412 on the side wall of the diversion module 4 or as a vertical liquid flow port 413 opening downward.
[0056] Preferably, as an example, in a specific embodiment of the present invention, Fig.11 and Fig.12 As shown, the flow dividing module 4 has a central pipeline 415 and two peripheral pipelines 411, wherein the second end of one peripheral pipeline 411 is arranged on the side wall of the flow dividing module 4 as a horizontal liquid flow opening 412, and the second end of the other peripheral pipeline 411 is opened downward as a vertical liquid flow opening 413; the central pipeline 415 of the flow dividing module is connected with the central pipeline 311 of the screening module;
[0057] The flow dividing module 4 further comprises: a shell 401 of a preset length and a pipe sleeve 402 , wherein the shell 401 is arranged outside the flow dividing module, and the pipe sleeve 402 is arranged inside the shell and located between the horizontal liquid flow port 412 and the vertical liquid flow port 413 .
[0058] Through the above arrangement, the water injection position of different reservoir layers can be controlled by reasonably setting the length of the outer shell 401 and the pipe sleeve 402. Taking water injection as an example, by using the measuring and adjusting device of the present invention, the water flowing out of the horizontal liquid flow port 412 can flow downward through the annular gap 403 formed between the outer shell 401 and the pipe sleeve 402, and by setting the length of the outer shell to the position of a suitable reservoir layer, the water can flow out from the bottom of the outer shell to the corresponding reservoir layer; and the water flowing out of the vertical liquid flow port 413 flows downward through the annular gap 404 formed between the pipe sleeve 402 and the central pipe 415, and by setting the length of the pipe sleeve to the position of a relatively deeper reservoir layer, the water can flow out from the bottom of the pipe sleeve 402 to the corresponding deeper reservoir layer. Therefore, by reasonably designing the structure of the diversion module, water injection or oil production of multiple reservoir layers can be achieved.
[0059] Preferably, as an example, the length of the central pipe 415 of the diversion module 4 can be set according to actual conditions (for example, the length of the central pipe 415 can also be shorter than the length of the sleeve 402). When there is no need to use the central pipe to lower the monitoring equipment, a wire plug (not shown in the figure) can also be provided at the bottom thereof, so that the solid impurities falling back at the central pipe of the flow monitoring module 2 can be collected in the central pipe.
[0060] In the technical solution of the present invention, by setting up a screening module 3 and a diversion module 4, the liquid (water or oil) in a peripheral pipeline can flow out or flow in from the sieve holes in a screening module 3, thereby correspondingly managing the water or oil in one reservoir layer, while the liquid in other peripheral pipelines can flow out or flow in from the liquid flow port in the diversion module 4, correspondingly managing the water or oil in one or more other reservoir layers, thereby achieving the management and control of the water injection volume or oil production volume of multiple reservoir layers by using only one of the above-mentioned measuring and adjusting devices.
[0061] In addition, as an example, in a preferred embodiment of the present invention, Figure 1 As shown, a protective shell 201 is provided outside the flow monitoring module 2 .
[0062] Preferably, as an example, the outer surface of the flow regulating device 12 is provided with a protective coating for anti-corrosion or anti-rust, so as to prevent the flow regulating device 12 from being corroded or rusted when immersed in water or oil.
[0063] Preferably, as an example, the flow monitoring device may be a flow sensor.
[0064] For example, in a preferred embodiment of the present invention, Figures 1 to 13 As shown, three flow regulating devices 12 are provided, and three peripheral pipes are also provided for the flow monitoring module 2 and the screening module 3, respectively. The diversion module 4 has two peripheral pipes, and the second end of one of the peripheral pipes is provided as a horizontal liquid flow port 412 on the side wall of the diversion module 4, and the second end of the other peripheral pipe is provided as a vertical liquid flow port 413 opening downward. In this embodiment, the three flow regulating devices 12 independently regulate and control the three peripheral pipes, and the three peripheral pipes in the flow monitoring module 2 are respectively provided with flow monitoring devices 213 to monitor the flow data in the three peripheral pipes in real time. Fig.13 , taking water injection as an example, the water in one of the peripheral pipes flows out from the sieve holes at the screening module 3 to the first reservoir layer, the water in another peripheral pipe flows from the horizontal liquid flow port 412 in the diversion module 4 to the annular space 403 and continues to flow downward until it flows from the bottom of the shell to the second reservoir layer, and the water in the remaining peripheral pipe flows from the vertical liquid flow port 413 in the diversion module 4 to the annular space 404 and continues to flow downward until it flows from the bottom of the sleeve 402 to the third reservoir layer. Therefore, the outflow position of the water in the corresponding reservoir layer can be controlled by reasonably setting the length of the shell and the sleeve. When performing stratified oil production, the structural principle is the same as that of stratified water injection, except that the liquid flows in the opposite direction, which will not be elaborated here. It can be seen that the control of water injection or oil production in three reservoir layers can be achieved by using only one downhole production dynamic measurement and adjustment device.
[0065] In addition, in another embodiment of the present invention, if the number of control layers of the reservoir layer is to be further increased, multiple flow regulating devices 12 and corresponding peripheral pipes can be provided, and the number of screening modules 3 can be increased, and the length of the diversion module 4 and the number of the lateral liquid flow ports 412 and the pipe sleeves thereon can also be increased, and different lateral liquid flow ports 412 correspond to different reservoir layers. Of course, multiple downhole production dynamic measurement and adjustment devices of the present application can also be combined according to actual conditions to achieve the management of more reservoir layers.
[0066] To sum up, in the technical solution of the present invention, by reasonably designing the integrated structure of the above-mentioned downhole production dynamic measurement and adjustment device, it is possible to manage multiple layers of oil reservoirs by only using the above-mentioned one measurement and adjustment device provided by the present application, thereby greatly reducing the cost and construction difficulty; further, it is also possible to simultaneously realize flow regulation and parameter monitoring of multiple layers of oil reservoirs, and can also be flexibly set according to actual conditions, which has positive significance and an important role in realizing intelligent stratified mining, efficiently controlling water and increasing oil, and improving oil reservoir recovery.
[0067] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
