Description

Technical Field

[0001] The utility model relates to the technical field of gas field exploitation, in particular to an intelligent plunger drainage and gas production device. Background Art

[0002] In the development of low-pressure gas fields and condensate gas fields, wellbore liquid accumulation is one of the main problems that restrict the stable and high production of gas wells. The liquid in the gas well is usually distributed in the gas phase in the form of droplets and carried to the ground by the gas. When the gas cannot provide enough energy to continuously carry the liquid, liquid will accumulate at the bottom of the gas well, causing the gas well to reduce production. Therefore, water-producing gas wells are usually treated by drainage gas production to timely discharge the liquid at the bottom of the well. Plunger gas lift is a simple and efficient method of drainage gas production. As a solid sealing interface, the plunger separates the lifting gas and the lifted liquid, reducing gas crossflow and liquid fallback.

[0003] It is found in long-term use that the outer peripheral side of the plunger is usually fixed, and the distance from the inner wall of the pipe is always consistent during the rising and falling process inside the pipe. Therefore, it will encounter partial resistance when descending inside the pipe, thereby reducing the working efficiency of drainage and gas production. For this reason, it is necessary to propose an intelligent plunger drainage and gas production device to provide a new technical solution to solve the technical problems mentioned in the above patent.

[0028] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0029] Embodiment 1:

[0030] Please refer to Figure 1-Figure 5 , an intelligent plunger drainage and gas collection device, comprising a plunger moving component 1, a drainage component 2 is installed on the outer side of the bottom of the plunger moving component 1;

[0031] When in use, the plunger moving component 1 can be moved up and down inside the pipeline, and at the same time cooperate with the drainage component 2 to discharge the liquid inside the pipeline, thereby completing the work of drainage and gas collection.

[0032] The plunger moving assembly 1 comprises a power storage module 3 , a straightening module 4 and a buffer module 5 . The top of the power storage module 3 is fixedly connected with the straightening module 4 , and the top of the straightening module 4 is fixedly connected with the buffer module 5 .

[0033] The plunger moving assembly 1 also includes a control module 6, a sensor module 7 and a drainage module 8. The control module 6 is fixedly connected to the bottom of the power storage module 3, the sensor module 7 is fixedly connected to the bottom of the control module 6, the drainage module 8 is fixedly connected to the bottom of the sensor module 7, and a stepping motor, a transmission mechanism, a water outlet valve and a water outlet are arranged on the inner side of the drainage module 8.

[0034] The plunger moving assembly 1 also includes a first fixed column 9, a connecting column 10 and a second fixed column 11. The first fixed column 9 is fixedly connected to the bottom of the drainage module 8, the connecting column 10 is fixedly connected to the center position of the bottom of the first fixed column 9, and the second fixed column 11 is fixedly connected to the bottom of the connecting column 10.

[0035] Specifically: through the setting of the buffer module 5, the plunger moving assembly 1 can have a buffering effect after it rises to the top; through the setting of the straightening module 4, the plunger moving assembly 1 can be reset when it moves up and down inside the pipeline, thereby avoiding the displacement of the plunger moving assembly 1 inside the pipeline and affecting the drainage and gas production; through the setting of the power storage module 3, the plunger moving assembly 1 can be provided with a power storage effect; through the coordinated use of the control module 6 and the sensor module 7, the movement of the plunger moving assembly 1 inside the pipeline can be monitored by a computer; through the coordinated use of the first fixed column 9, the connecting column 10 and the second fixed column 11, the plunger moving assembly 1 can have a buffering effect after it descends to the bottom;

[0036] Four first flow grooves are arranged in a circumferential array on the outer circumference of the first fixing column 9 , and a plurality of second flow grooves are arranged in a circumferential array on the outer circumference of the second fixing column 11 .

[0037] The drainage component 2 includes a fixed shaft 12 and a first supporting plate 13. Four rotation grooves are opened on the top of the outer peripheral side of the second fixed column 11, and the position of each rotation groove corresponds to the first circulation groove. The fixed shaft 12 is fixedly connected to the inner side of the rotation groove, and the first supporting plate 13 is rotatably connected to the outer side of the fixed shaft 12. The four first supporting plates 13 are arranged to wrap the connecting column 10. A plurality of third circulation grooves are opened on the side of the first supporting plate 13 away from the connecting column 10, and the position and size of the third circulation grooves correspond to the second circulation grooves.

[0038] The drainage assembly 2 also includes a second supporting plate 14 and a limiting plate 15. A second supporting plate 14 is arranged between every two first supporting plates 13. Both ends of the second supporting plate 14 are inserted into the inner sides of the two adjacent first supporting plates 13 and are clearance-fitted with the first supporting plates 13. Both ends of the second supporting plate 14 are fixedly connected to the limiting plate 15. The limiting plate 15 and the inner sides of the first supporting plates 13 are clearance-fitted, and the limiting plate 15 limits the end of the second supporting plate 14 located on the inner side of the first supporting plate 13.

[0039] Specifically: by providing a plurality of second flow grooves on the outer side of the second fixed column 11, the gap between the second fixed column 11 and the inner circumference of the pipeline can be increased, and when the plunger moving assembly 1 descends, the influence of the liquid inside the pipeline on the resistance of the bottom of the second fixed column 11 can be reduced, thereby increasing the descending speed of the plunger moving assembly 1;

[0040] At the same time, by designing that the positions and sizes of the second circulation grooves correspond to those of the third circulation grooves, the liquid can pass through the third circulation grooves at the same time as it passes through the second circulation grooves, so that the four first supporting plates 13 can be squeezed to a state parallel to the outer peripheral surface of the second fixed column 11 by the overall descent of the plunger moving assembly 1 in coordination with the liquid inside the pipeline, so that a gap can be left between the first supporting plates 13 and the inner peripheral side of the pipeline, thereby further improving the descending speed of the plunger moving assembly 1 inside the pipeline;

[0041] When the second fixed column 11 descends to the bottom and then rises, the liquid located inside the first flow grooves can be guided through the four first flow grooves opened on the outer peripheral side of the first fixed column 9, and the liquid passes through the first flow grooves and flows to the side of the first supporting plate 13 close to the connecting column 10, so that the four first supporting plates 13 can be opened by the impact of the liquid, and the first supporting plate 13 can be rotated with the fixed axis 12 as the center of the circle, and at this time, the top of the first supporting plate 13 will be set in close contact with the inner side wall of the pipeline;

[0042] By setting the second supporting plate 14, the gap between every two first supporting plates 13 can be filled when the four first supporting plates 13 are in an open state, so as to support the liquid inside the pipeline and drive it out of the pipeline. At the same time, by setting the limiting plate 15, the phenomenon of the two ends of the second supporting plate 14 being separated from the inner side of the first supporting plate 13 can be avoided.
