Description

Technical Field

[0001] This invention relates to the field of gas well equipment technology, and in particular to a pumping device for draining fluid and producing gas in gas wells. Background Technology

[0002] In existing gas well pumping systems, a pumping structure composed of a metal frame and vulcanized rubber is commonly used to achieve efficient pumping of downhole fluids. However, in actual operation, the rubber, as a key component for sealing and flexible propulsion, is frequently subjected to high-frequency reciprocating motion and complex liquid media (such as sand-containing or corrosive liquids), making it highly susceptible to aging, wear, and tearing. Once the rubber component is damaged or detached, its fragments can easily fall into the wellbore with the fluid, leading to the accumulation of foreign objects. This not only affects the normal operation of subsequent pumping equipment but may also cause blockages in the pump body or downhole pipelines, and even damage downhole tools. In severe cases, complex retrieval operations are required, increasing maintenance costs and reducing production efficiency.

[0003] Furthermore, existing pumping devices often lack sufficient consideration for the service life of rubber and anti-detachment structures in their structural design. Especially under long-term operation or high-load conditions, the rubber-metal connection is prone to local delamination due to poor sealing, stress concentration, and other factors, which further exacerbates the risk of breakage and detachment. Summary of the Invention

[0011] A further improvement of the pumping device for gas production well drainage and gas extraction of the present invention is that the pumping module includes a pumping head section, a first rod section, a pumping cone section, a second rod section, a pumping tail section and a third rod section that are coaxially and fixedly connected in sequence.

[0012] The suction head section, the first rod section, the suction cone section, and the second rod section are inserted into the connecting channel. The first rod section corresponds to the limiting ring, and the suction cone section and the second rod section correspond to the second channel. The liquid suction unit is sleeved on the suction tail section, and the top end of the guide module is fixedly connected to the bottom end of the third rod section.

[0013] A further improvement of the pumping device for gas extraction and drainage in a gas well according to the present invention is that the tail section of the pumping device is provided with a first groove extending in the height direction.

[0014] A further improvement of the pumping device for gas production well drainage and gas extraction of the present invention is that the guiding module includes a guiding connector, a guiding rod section and a guiding cone head that are coaxially and fixedly connected in sequence, the material collection module is connected to the guiding cone head, and the receiving groove corresponds to the guiding rod section.

[0015] A further improvement of the pumping device for gas extraction and drainage in a gas well according to the present invention is that the guide cone has several inclined drainage channels, and the bottom of the material collection module is connected to the top of the drainage channels.

[0016] A further improvement of the pumping device for gas extraction and drainage in a gas well according to the present invention is that a filter screen is provided on the material collection module corresponding to the position of the drainage channel.

[0017] A further improvement of the present invention for a pumping device for gas extraction and drainage in a gas well is that the liquid suction unit includes multiple sets of conical plugs, the multiple sets of conical plugs are coaxially arranged and sequentially fixedly connected end to end, and the conical plugs are sleeved and connected to the pumping tail section.

[0020] This invention connects to the connecting module via an external drive device, enabling the drive device to move the suction device up and down within the tubing, thus facilitating the collection of liquid from the gas well.

[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention. The following embodiments are used to illustrate this invention but should not be used to limit the scope of this invention.

[0032] The following is combined Figures 1 to 6 The present invention describes a pumping device for draining and producing gas from a gas production well. The pumping device is disposed inside an oil pipe 1 and includes:

[0033] Connection module 2, the top of which is used to connect to the drive device, and a connection channel is formed inside the connection module 2;

[0034] The top of the suction module 3 is connected to the connection channel, and the suction module 3 is fitted with a liquid absorption unit 6, which is made of elastic material.

[0035] The top end of the guide module 4 is connected to the bottom end of the suction module 3, and the guide module 4 has a Y-shaped channel 44 inside.

[0036] The material collection module 5 is sleeved on the guide module 4, and the material collection module 5 has a receiving groove at the position corresponding to the liquid absorption unit 6.

[0037] Preferably, an external drive device is connected to the connection module 2, enabling the drive device to move the suction device up and down within the tubing 1, thus facilitating the collection of liquid from the gas well. A suction module 3 is connected to the connection module 2, and a suction unit 6 is attached to the suction module 3 for easy replacement. A guide module 4 is provided, with a Y-shaped channel 44 inside, to effectively divert and guide the liquid, allowing it to flow more smoothly into the tubing 1 and increasing its flow rate. A collection module 5 is fitted onto the guide module 4, and a receiving groove is provided corresponding to the position of the suction unit 6, accurately catching debris falling from the suction unit 6 and preventing debris from clogging the gas well. When the suction device is in a downward position, the suction unit 6 deforms to create a gap between the suction unit 6 and the tubing 1, facilitating liquid flow. When the suction device is in an upward position, the suction unit 6 deforms to close the gap between the suction unit 6 and the tubing 1, facilitating liquid ascent.

[0038] In a preferred embodiment of the pumping device for gas extraction and drainage in a gas production well according to the present invention, such as... Figure 2 and Figure 3 As shown, the connection module 2 includes a first connection part 21 and a second connection part 22. The first connection part 21 is used to connect to the drive device. The top end of the second connection part 22 is fixedly connected to the bottom end of the first connection part 21. The connection channel is opened in the second connection part 22. The side of the second connection part 22 is provided with a first through hole 23 and a second channel 24. The first through hole 23 is connected to the connection channel, and the second channel 24 is connected to the connection channel. The bottom end of the first through hole 23 and the top end of the second channel 24 are positioned correspondingly. The inner wall of the connection channel is provided with a limiting ring corresponding to the position of the first through hole 23. The limiting ring is located above the second channel 24.

[0039] Preferably, the first connecting part 21 is designed as a standard interface, allowing for quick connection and disassembly with various types of drive equipment, facilitating the replacement of suitable drive equipment in different operating scenarios. The first connecting part 21 may be threaded, thus enabling a threaded connection between it and the drive equipment. The first connecting part 21 may also be a flange structure, tightly connected to the drive equipment via bolts. The outer surface of the first connecting part 21 may also undergo special treatments, such as chrome plating or painting, to enhance its corrosion resistance and wear resistance, extending its service life.

[0040] Preferably, the second connecting part 22 is cylindrical in shape and is integrally formed with the first connecting part 21 to ensure the stability and reliability of the connection. The second connecting part 22 is provided with a first through hole 23 and a second channel 24, so that the suction head section 31, the first rod section 35, the suction cone section 32, and the second rod section 36 can be smoothly connected to the connecting channel, facilitating observation of the connection status between the suction head section 31, the first rod section 35, the suction cone section 32, the second rod section 36, and the connecting channel. The limiting ring can limit the suction head section 31, effectively preventing it from detaching from the connecting channel and improving the connection stability between the suction head section 31 and the connecting channel. The limiting ring is used to limit and control the insertion depth and axial position of the connecting module 2, preventing over-insertion or offset of the connecting module 2. The suction cone section 32 is interference-fitted with the second channel of the second connecting part, thereby enhancing the connection stability between the connecting module 2 and the suction module 3. In actual suction operation, it can effectively prevent loosening or detachment of the connection caused by impact or fluid flow disturbance, ensuring that the suction module 3 and the connecting module 2 are always in a coaxial and stable state during long-term reciprocating motion, improving the operational reliability of the device, effectively solving structural reliability problems such as component misalignment and detachment in high-frequency suction operation, and significantly enhancing the working continuity and safety of the suction device in complex downhole environments.

[0041] Furthermore, such as Figure 3 and Figure 4 As shown, the suction module 3 includes a suction head section 31, a first rod section 35, a suction cone section 32, a second rod section 36, a suction tail section 33, and a third rod section that are coaxially and fixedly connected in sequence.

[0042] The suction head section 31, the first rod section 35, the suction cone section 32, and the second rod section 36 are inserted into the connecting channel. The first rod section 35 corresponds to the limiting ring, and the suction cone section 32 and the second rod section 36 correspond to the second channel 24. The liquid suction unit 6 is sleeved on the suction tail section 33, and the top end of the guide module 4 is fixedly connected to the bottom end of the third rod section.

[0043] Preferably, the first through hole 23 is dumbbell-shaped, the top of the second channel 24 is round and the bottom is strip-shaped, and the top of the second channel 24 corresponds to the bottom of the first through hole 23. When the pumping module 3 and the connecting module 2 are connected, the pumping head section 31 and the first rod section 35 enter the connecting channel from the second channel 24, which facilitates insertion and connection into the connecting channel.

[0044] Preferably, the suction module 3 is made of high-strength alloy material, which can improve the structural strength of the suction module 3. The good fit between the first rod segment 35 and the inner wall of the connecting channel and the corresponding limiting ring improve the connection stability between the suction head segment 31 and the connecting channel.

[0045] Furthermore, such as Figure 1 As shown, the suction tail section 33 has a first groove 34 extending along the height direction. This first groove 34 can prevent the liquid suction unit 6 from seizing up with the suction module 3 after long-term use, making it convenient to replace the liquid suction unit 6. At the same time, when the suction module 3 descends, the first groove 34 can conveniently guide the liquid to flow upward along the first groove 34.

[0046] Preferably, the length of the connecting channel is greater than the total length of the pumping head section 31, the first rod section 35, the pumping cone section 32, and the second rod section 36 along the axial direction, thereby allowing the pumping module 3 to have axial movement clearance within the connecting channel, giving it limited axial freedom of movement. During the pumping process, the pumping module 3 may experience a short-range longitudinal lift dynamic response due to the influence of liquid rebound force, fluid resistance, or driving inertia. This structural design allows the pumping module 3 to achieve short-range sliding within the connecting channel, avoiding stress concentration or impact damage caused by complete fixation. Simultaneously, it provides dynamic buffer space for the suction process of the suction unit 6, improving the stability and adaptability of the system. The design of the connecting channel being longer than the total length of the pumping head section 31, the first rod section 35, the pumping cone section 32, and the second rod section 36 along the axial direction ensures the coaxial positioning of the pumping module 3 while giving it short-range longitudinal movement capability. This effectively absorbs hydraulic shock, alleviates structural stress fluctuations during the pumping process, improves the operational stability and fatigue resistance of the pumping device, thereby extending the service life of the device and improving pumping efficiency.

[0047] Furthermore, such as Figure 4 and Figure 5 As shown, the guiding module 4 includes a guiding connector 41, a guiding rod segment 42, and a guiding cone 43 that are coaxially and fixedly connected in sequence. The material collection module 5 is connected to the guiding cone 43, and the receiving groove corresponds to the guiding rod segment 42.

[0048] Preferably, the guide connector 41 includes a first cylindrical section, a frustum section, and a second cylindrical section arranged sequentially, wherein the outer diameter of the second cylindrical section is smaller than the outer diameter of the first cylindrical section, and the outer diameter of the guide rod section 42 is smaller than the outer diameter of the second cylindrical section.

[0049] Furthermore, the guide cone 43 has several inclined drainage channels 45, and the bottom of the collection module 5 and the top of the drainage channels 45 are connected.

[0050] Preferably, when the guide module 4 is driven to move longitudinally within the oil pipe 1 to draw liquid, the guide cone 43 can effectively guide the direction of travel of the guide module 4 through its conical structure, ensuring that the guide module 4 maintains a stable axial posture within the oil pipe 1 and avoiding operational abnormalities such as deviation or jamming. The guiding function of the guide cone 43 within the oil pipe 1 not only optimizes the movement trajectory of the guide module 4 but also improves the stability and accuracy of the drawing operation. In addition, the Y-shaped channel 44 allows the liquid entering the guide module 4 to be evenly distributed in two different directions and transported to the outside of the guide module 4, further improving the uniformity and efficiency of liquid conduction, achieving directional guidance and smooth transmission of the liquid, thereby improving the conduction efficiency and extraction integrity of the liquid during the drawing process; the drain channel 45 is used to quickly empty the liquid in the annular cavity when the cone is lifted, and guides the rubber located in the annular cavity towards the bottom of the annular cavity under the suction force during liquid emptying, thereby forming a better collection effect and further collecting fine impurities.

[0051] Preferably, the outer diameter of the collecting module 5 matches the inner diameter of the oil pipe 1, and the outer diameter of the guide cone 43 at its maximum cross-section matches the inner diameter of the oil pipe 1, so that the aging debris of the suction unit 6 can be ensured to enter the receiving groove of the collecting module 5.

[0052] Furthermore, the material collection module 5 is equipped with a filter screen 51 at the position corresponding to the drainage channel 45. The filter screen 51 can prevent debris in the receiving tank from entering below the guide cone 43, and can facilitate the smooth passage of liquid in the gas well.

[0053] Furthermore, the liquid suction unit 6 includes multiple sets of conical plugs, which are coaxially arranged sequentially and fixedly connected end to end. The conical plugs are sleeved and connected to the suction tail section 33. The top lip of the conical plug is arc-shaped, and the diameter of the top lip of the conical plug is larger than the inner diameter of the oil pipe 1.

[0054] When the suction unit 6 is inserted axially along the tubing 1, the conical plug will undergo elastic deformation due to restriction when it comes into contact with the inner wall of the tubing 1. The top lip of the conical plug will contract radially under the action of axial thrust, so that the suction unit 6 can slide smoothly along the inner wall of the tubing 1. During this sliding process, when the suction unit 6 comes into contact with the liquid in the gas well, multiple sets of conical plugs will further contract and fit together due to hydraulic action, and through their own conical surface guiding structure, they will directionally guide the liquid in the gas well they come into contact with along the direction of the connecting module 2 along their outer wall, thereby achieving effective squeezing and accumulation of the liquid in the gas well.

[0055] When it is necessary to pump the liquid accumulated in the gas well in the tubing 1 upward, it is only necessary to drive the liquid suction unit 6 to move upward along the longitudinal direction of the tubing 1. During this process, the top lip of multiple sets of conical plugs is deformed outward under the reverse drag action and continuously forms an annular friction seal with the inner wall of the tubing 1, effectively blocking the backflow or leakage of liquid in the gas well. The annular friction seal continues to act during the upward pulling process to ensure the formation of a closed fluid channel during the pumping process, thereby achieving efficient pumping and conduction of liquid in the gas well.

[0056] Preferably, the conical plug structure not only realizes the bidirectional sealing and sliding function of the suction unit 6 in the tubing 1, but also has the functions of automatic diameter change and flow guidance, dynamic sealing and suction assistance, which significantly improves the suction efficiency and sealing stability of the suction device in the complex liquid environment downhole, avoids liquid leakage or backflow during the suction process, and enhances the overall operational reliability and safety.

[0057] Specifically, the smaller diameter ends of multiple sets of conical plugs are all positioned towards the guide module 4. This allows the smaller diameter ends of the conical plugs to form a guiding fit with the inner wall of the tubing 1 as the suction unit 6 descends along the tubing 1, enabling stable sliding within the tubing 1. Simultaneously, when encountering liquid resistance in the gas well or bends in the tubing 1, the conical guide structure guides the suction unit 6 to advance stably along the central axis of the tubing 1. This facilitates effective sealing contact between the top lip of the conical plug and the inner wall of the tubing 1 during the pullback suction process, forming a radial sealing structure. This allows for continuous suction of liquid from the gas well during the upward movement, preventing backflow and improving suction efficiency and reliability. It effectively enhances the guiding stability of the suction unit 6 within the tubing 1 and the sealing reliability during suction, achieving both dynamic guidance and sealing functions during liquid suction in the gas well. This avoids the problems of damage, detachment, and sealing failure associated with traditional rubber structures, making it suitable for suction operations in long-stroke, deep wells.

[0058] Furthermore, the conical plug is made of rubber.

[0059] Preferably, the conical plug made of rubber not only has good elasticity, allowing it to better conform to the inner wall of the oil pipe 1 during liquid suction and effectively prevent liquid leakage, but the rubber material also has a certain degree of wear resistance, which can extend the service life of the conical plug. Furthermore, the arrangement of multiple sets of conical plugs coaxially arranged and fixedly connected end-to-end makes the entire liquid suction unit 6 structure more stable, maintaining a good shape during suction and ensuring smooth liquid discharge. At the same time, the conical plug is sleeved and connected to the suction tail section 33; this connection method facilitates installation and disassembly, allowing for convenient and quick replacement when the conical plug is worn or damaged.

[0060] Preferably, nitrile rubber (NBR) can be selected. NBR possesses excellent oil resistance, abrasion resistance, and resilience, making it particularly suitable for long-term operation in liquid environments. It effectively prevents structural failures caused by material aging, expansion, or swelling. The flexibility and compressibility of NBR allow the conical plug to automatically undergo radial contraction deformation during downward movement, thus smoothly passing through tubing 1 and avoiding jamming or breakage. During upward pumping, its good resilience allows it to return to the preset sealing shape, ensuring a tight fit between the top lip and the inner wall of tubing 1, achieving a stable axial seal. This ensures that the liquid in the gas well can be continuously and effectively pumped to the surface, preventing backflow or leakage during the pumping process.

[0061] Preferably, the structure of the liquid suction unit is constrained by the inner wall of the oil pipe, which allows the liquid to pass through the outer edge of the liquid suction unit and gradually gather to the upper surface area of ​​the liquid suction unit. At this time, the liquid completes one collection and directional guidance inside the oil pipe, realizing the process of liquid suction and upward guidance.

[0062] By linking the pumping module and the liquid suction unit in a coordinated descent, the liquid suction unit actively compresses and guides the liquid in the gas well during the descent, improving pumping efficiency. The structural linkage between the liquid suction unit and the pumping module ensures the stability and reliability of the pumping device's transmission, effectively preventing pumping failure or poor liquid suction caused by structural loosening or asynchrony. At the same time, it avoids the detachment or damage of sealing rings caused by nonlinear extrusion in traditional pumping devices.

[0063] In one specific implementation case, when it is necessary to pump the liquid in the tubing 1, the connecting module 2 is first connected to the external drive device. Then, the external drive device drives the connecting module 2 to move longitudinally downward along the axis of the tubing 1. During the downward movement of the connecting module 2, the pumping module 3 moves downward synchronously, and the liquid suction unit 6 undergoes unidirectional compression deformation due to its self-adaptive structure, enabling it to collect liquid. During this downward movement, the liquid in the gas well is gradually gathered to the upper part of the liquid suction unit 6 by the directional guidance of the guiding module 4. When the liquid in the suction chamber needs to be pumped to the ground, the external drive device drives the connecting module 2 to move longitudinally upward along the oil pipe 1. As the connecting module 2 and the suction unit 6 move upward as a whole, the suction unit 6 forms a sealed fit due to the friction between its side wall and the oil pipe 1, allowing the sucked liquid to pass through the side wall of the suction unit 6 and be transferred to the upper part of the suction unit 6, thus achieving effective suction of the liquid. When the suction unit 6 is damaged and falls naturally during the suction process, the impurities that fall will be collected by the collection module 5. The guide module 4 not only provides a stable sliding path for the suction module 3 along the axis of the oil pipe 1, but also stably guides the liquid to the upper part of the suction module 3, thereby improving the liquid drainage efficiency and reducing structural wear.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
