Description

Technical Field

[0001] The invention relates to the technical field of water distributors, in particular to an anti-blocking water distributor for oil field development. Background Art

[0002] The water distributor (also known as the distributor or injection controller) plays a vital role in the oilfield water injection system. It can accurately control and distribute the amount of water injected into the reservoir and its pressure, ensuring the efficiency and stability of the water injection task, thereby optimizing the displacement effect and improving the recovery factor.

[0003] In actual operation, water distributors select different types of injection fluids according to specific geological conditions and production requirements. The selection of these fluids and technical considerations are aimed at better managing reservoirs and improving oil recovery. However, during the injection process, the problem of impurities blocking the outlet cannot be ignored. These impurities may come from the following aspects:

[0004] The water source itself carries: surface water, groundwater or seawater that has not been fully treated contains silt, suspended matter, microorganisms, etc.

[0005] Aging of water pipelines: Corrosion products such as rust and scale may accumulate inside water pipelines that have been used for a long time.

[0006] Equipment wear: Mechanical wear of metal parts produces fine particles.

[0007] These impurities will cause the water distributor to not work properly, affecting the injection effect. In addition, after the water injection is completed, the liquid in the formation may flow back into the water distributor, which will not only further affect the injection effect, but may also cause equipment corrosion and blockage. More seriously, the liquid in the high hydraulic layer may flow into the low hydraulic layer through the water distributor, interfering with normal oil production operations. Summary of the invention

[0047] The following is combined with Figure 1 -Attached Figure 8 , the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0048] Embodiment 1: An oilfield exploitation anti-blocking water distributor, such as Figure 1-Figure 4 As shown, it includes: a shell 1, which is provided with a plurality of drainage ports 101; an upper joint 102, which is threadedly installed on one end of the shell 1; a first sleeve 103, which is slidably arranged in the shell 1 and is provided with a plurality of liquid guide holes 1031, the liquid guide holes 1031 are inclinedly arranged, and the liquid guide holes 1031 are used to guide the liquid to rotate, and the diameter of the liquid guide holes 1031 is larger than the diameter of the drainage ports 101, and is used to intercept impurities in the liquid in batches; a second sleeve 104, which is slidably arranged in the shell 1, and the two ends of the second sleeve 104 are respectively in contact with the first sleeve 103 and the upper joint 102; an adjusting mechanism, which is arranged in the shell 1, and the adjusting mechanism is used to adjust the opening size of the liquid guide holes 1031 on the first sleeve 103 by pressure.

[0049] In the above scheme, the multiple liquid discharge ports 101 and the multiple liquid guide holes 1031 are uniformly distributed circumferentially, the opposite ends of the multiple liquid guide holes 1031 are higher than the other end, and the liquid flows downward in a spiral on the outside of the liquid guide holes 1031 after passing through the liquid guide holes 1031. A rubber pad is provided on the lower surface of the first sleeve 103 to increase the friction between the first sleeve 103 and the shell 1 to prevent the first sleeve 103 from rotating in the shell 1.

[0050] Specific working principle: During the liquid injection process, the liquid passes through the upper joint 102 and the regulating mechanism. During the liquid passing through the regulating mechanism, the regulating mechanism controls a specified number of liquid guide holes 1031 to connect the inner and outer sides of the first casing 103. Then the liquid enters between the first casing 103 and the shell 1 through the corresponding liquid guide holes 1031. Then the liquid is injected into the reservoir through the drain port 101 to maintain the reservoir pressure, improve the recovery rate and optimize the displacement effect. Its design and function are intended to ensure efficient and stable completion of the water injection task, and different types of injection fluids are selected according to specific geological conditions and production needs.

[0051] The liquid rotates while passing through the liquid guide hole 1031. The rotating liquid guides the liquid and impurities to rotate near the inner wall of the shell 1, reducing the phenomenon of impurities adhering to the discharge port 101 for a long time and causing blockage, ensuring that the device continues to inject liquid into the oil reservoir and ensure the continuity of oil field exploitation.

[0052] like Figure 1-Figure 4 As shown, the adjustment mechanism includes: a sliding sleeve 2, which is slidably arranged in the housing 1, the second sleeve 104 and the first sleeve 103 are both slidably connected to the sliding sleeve 2, a spring 201 is installed between the sliding sleeve 2 and the second sleeve 104, and the sliding sleeve 2 is provided with a plurality of rectangular holes 2011, and the rectangular holes 2011 are used to communicate with adjacent liquid guide holes 1031; a guide rod 202, which is fixed to the sliding sleeve 2, penetrates the second sleeve 104 and is slidably connected thereto; a fixed seat 203, which is fixed to the sliding sleeve 2, and the fixed seat 203 is provided with a plurality of notches, and the notches of the fixed seat 203 are used to allow liquid to pass through; a ball 204, which is installed on the fixed seat 203.

[0053] In the above solution, when the spring 201 between the sliding sleeve 2 and the second sleeve 104 is not compressed, the sliding sleeve 2 blocks all the liquid guide holes 1031 , and the fixing seat 203 is located below the rectangular hole 2011 .

[0054] Specific working principle: When the liquid passes through the regulating mechanism, the liquid flows and impacts the ball 204, and the ball 204 is impacted by the liquid and fits on the fixed seat 203, and the ball 204, the fixed seat 203 and the sliding sleeve 2 move downward. The sliding sleeve 2 compresses the spring 201 at the same time, and part of the liquid flows downward through the notch on the fixed seat 203, which facilitates the liquid to flow to the shell 1 at the remaining depth.

[0055] The pressure of the injected liquid in this process is used to control the moving distance of the sliding sleeve 2, so that the rectangular holes 2011 on the sliding sleeve 2 are connected to different numbers of liquid guide holes 1031, and the subsequent liquid enters between the shell 1 and the first sleeve 103 through the rectangular holes 2011 and the corresponding liquid guide holes 1031, and the subsequent liquid is injected into the oil reservoir through the drain port 101.

[0056] During the liquid injection process, by changing the pressure of the injected liquid and the number of liquid guide holes 1031 connected to the rectangular hole 2011, the liquid flow area is increased, thereby expanding the liquid flow rate, making it easier for the device to adjust the flow rate of the liquid injected into the oil reservoir, so that the device can select the optimal injection flow rate according to the actual situation of the oil reservoir, thereby controlling the oil reservoir production cycle to be in the shortest time.

[0057] When the injection is stopped, the pressure of the injected liquid disappears, and under the influence of the elastic force of the spring 201, the sliding sleeve 2 moves in the opposite direction to reset. At this time, the sliding sleeve 2 resumes to cover the liquid guide hole 1031, and the liquid stops flowing, thereby preventing the liquid in the reservoir from flowing back into the first casing 103 to affect the subsequent injection effect, and preventing the refluxed liquid from corroding or clogging the water distributor.

[0058] like Figure 1 and Figure 2 As shown, the outer side surface of the shell 1 is provided with an external thread, and a rotating shell 3 is installed at the external thread of the shell 1. The rotating shell 3 is used to cover a corresponding number of liquid discharge ports 101.

[0059] In the above scheme, the distance between the upper and lower adjacent drainage ports 101 and the liquid guide holes 1031 is set according to actual needs. During the installation of the device, the rotating shell 3 is first rotated to adjust the number of drainage ports 101 covered by the rotating shell 3 to control the range of liquid outflow, thereby ensuring that the injected liquid is more evenly distributed in the entire oil reservoir, reducing the undisplaced area and improving the sweep coefficient.

[0060] Embodiment 2: Based on embodiment 1, Figure 2-Figure 5 As shown, it also includes: a third sleeve 4, installed on the outside of the first sleeve 103; a limiting column 401, penetrating the third sleeve 4 and the first sleeve 103 and slidably connected with the two, and a tension spring 402 is installed between the third sleeve 4, and the sliding sleeve 2 is provided with a plurality of blind holes 403, and the limiting column 401 limits the movement of the sliding sleeve 2 through adjacent blind holes 403.

[0061] In the above scheme, in the accompanying drawings, there are six limit posts 401 distributed circumferentially, and the actual number can be set according to actual needs, wherein the facing ends of the six limit posts 401 are all hemispherical, and the blind holes 403 are hemispherical. In the initial state, the tension spring 402 is in a stretched state. When the injected liquid is under different pressures, the sliding sleeve 2 moves to insert the limit posts 401 into different blind holes 403. At this time, under the limiting action of the limit posts 401, when the pressure change of the sphere 204 subjected to the liquid is greater than the limiting force generated by the limit posts 401, the sliding sleeve 2 will move again. The blind holes 403 at different positions are used to indicate that different numbers of liquid guide holes 1031 are in a connected state with the corresponding rectangular holes 2011, so that the device can accurately adjust the number of liquid guide holes 1031 connected to the rectangular holes 2011 by controlling the pressure of the injected liquid.

[0062] Embodiment 3: Based on embodiment 2, Figure 2 , Figure 4 and Figure 5 As shown, it also includes: a guide sleeve 5, which is installed on the outside of the first sleeve 103 and is located on the outside of the liquid guide hole 1031. The part of the guide sleeve 5 located between the discharge port 101 and the liquid guide hole 1031 is set to be a truncated cone, and the closer the guide sleeve 5 is to the rotating sleeve 501, the larger its cross-sectional area; the rotating sleeve 501 is installed on the outside of the first sleeve 103 and contacts with the guide sleeve 5. The guide sleeve 5, the rotating sleeve 501, the shell 1 and the first sleeve 103 constitute a flow path for the liquid.

[0063] In the above scheme, a guide hole is provided on the upper part of the guide sleeve 5, and the guide sleeve 5 is located between the shell 1 and the first sleeve 103. The third sleeve 4, the guide sleeve 5 and the rotating sleeve 501 are all slidably installed on the outside of the first sleeve 103. The guide sleeve 5 is used to guide the liquid flowing between the shell 1 and the first sleeve 103, and then cooperate with the guide hole 1031 to guide the liquid to rotate. Impurities in the liquid adhere to the truncated cone part of the guide sleeve 5, and then under the guiding effect of the truncated cone on the guide sleeve 5, the impurities in the liquid gather between the guide sleeve 5 and the rotating sleeve 501, further reducing the phenomenon of impurities blocking the discharge port 101.

[0064] like Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, it also includes: a rotating frame 6, which is rotatably arranged on the outside of the first sleeve 103 and fixedly connected to the rotating sleeve 501, and the first sleeve 103 and the guide sleeve 5 are both rotatably connected to the rotating sleeve 501; a first fixed shell 601, which is fixedly connected to the rotating sleeve 501, and the first fixed shell 601 is connected to the middle part of the guide sleeve 5; a sliding plug 602, which is slidably arranged in the first fixed shell 601, and the first sleeve 103 is provided with a through hole 603 and a guide groove 604, the through hole 603 is used to connect to the first fixed shell 601, and the sliding plug 602 is located in the guide groove 604 and slides.

[0065] In the above scheme, the first fixed shell 601 and the sliding plug 602 in the figure each have two circumferentially equidistantly distributed blades, and the rotating frame 6 is provided with four circumferentially distributed blades to attach Figure 5 For example, the inner diameter of the first sleeve 103 below the fixed seat 203 is larger than the inner diameter above it. When the sliding sleeve 2 moves downward, an annular groove is formed between the sliding sleeve 2 and the first sleeve 103, and the gap of the annular groove is larger than the particle size. The guide groove 604 is divided into two arc segments symmetrically distributed at the center and two bending segments symmetrically distributed at the center. During the process of injecting liquid into the reservoir, impurities accumulated between the guide sleeve 5 and the rotating sleeve 501 enter the first fixed shell 601. At the same time, during the process of liquid flowing through the liquid guide hole 1031 and rotating, the rotating liquid impacts the blades of the rotating frame 6, so that the rotating frame 6 drives the rotating sleeve 501, the two first fixed shells 601 and the two sliding plugs 602 to rotate, wherein the two sliding plugs 602 rotate along the guide groove 604. When the sliding plug 602 is located in the arc segment and moves, the sliding plug 602 The movable plug 602 remains stationary relative to the adjacent first fixed shell 601. When the sliding plug 602 is in the moving process in the bending section, the sliding plug 602 performs a reciprocating movement in the adjacent first fixed shell 601. When the first fixed shell 601 rotates to communicate with the adjacent through hole 603, the sliding plug 602 is just located in the adjacent bending section. The subsequent first fixed shell 601 rotates and the communication area with the adjacent through hole 603 gradually increases. At this time, the sliding plug 602 pushes the liquid and impurities in the first fixed shell 601. At the same time, the sliding plug 602 moves to gradually block the communication port between the first fixed shell 601 and the guide sleeve 5. After the impurities enter the annular groove formed by the sliding sleeve 2 and the first sleeve 103, the impurities follow the liquid to flow in the sliding sleeve 2. Thereafter, the above operation is repeated to ensure that the device continuously injects liquid into the reservoir.

[0066] Embodiment 4: Based on the embodiment 3, Figure 4 , Figure 6 and Figure 8As shown, it also includes: a second fixed shell 7, which is fixed to the rotating frame 6 and contacts with the first sleeve 103, and the second fixed shell 7 is used to cover the corresponding liquid guide hole 1031. The side of the second fixed shell 7 away from the first sleeve 103 is set as a rubber sheet; there are multiple limit blocks 701, which are all fixed in the guide sleeve 5, and the limit blocks 701 do not contact with the rotating frame 6. The limit blocks 701 are used to squeeze the elastic material of the second fixed shell 7.

[0067] In the above scheme, the elastic material of the second fixed shell 7 is an arc-shaped rubber sheet, the limit block 701 has six circumferentially evenly distributed, and the multiple circumferentially distributed liquid guide holes 1031 are divided into six rows. The second fixed shell 7 and the first sleeve 103 are sealed and slidable, and the limit blocks 701 are respectively opposite to a vertical row of liquid guide holes 1031. During the rotation of the rotating frame 6, the rotating frame 6 drives the second fixed shell 7 to rotate together. When the second fixed shell 7 covers an adjacent row of liquid guide holes 1031, the liquid guide holes 1031 cannot flow liquid at this time, and the limit block 701 squeezes the rubber sheet of the second fixed shell 7 at this time, so that the internal volume of the second fixed shell 7 becomes smaller, and then the liquid in the second fixed shell 7 flows in the opposite direction through the row of liquid guide holes 1031, that is, the row of liquid guide holes 1031 is recoiled to avoid impurities blocking the liquid guide holes 1031, thereby ensuring that the device continuously injects liquid into the reservoir, which helps to maintain the reservoir pressure, improve the recovery rate, and optimize the stability and efficiency of the entire production process.
