[0052] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0053] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0054] This embodiment provides a cleaning device for cleaning a gas lift ball to remove dirt such as sand, mud, oil and wax on the surface of the gas lift ball. The cleaning device is used in a gas lift oil production system to clean the gas lift ball after use, thereby reducing the wear and damage of the gas lift ball to the components, improving the oil production efficiency and extending the service life of the components.

[0055] Please refer to Figures 1 to 3The cleaning device 100 comprises a cylinder 110 having a cleaning chamber 111, a ball pusher 120, a first transmission shaft 141, a piston shaft 142 and a cleaning member 150. The cylinder 110 is provided with a ball inlet 112, a ball outlet 113, a liquid inlet 114 and a liquid outlet 115 respectively connected to the cleaning chamber 111. The ball pusher 120 is arranged in the cleaning chamber 111, and the ball pusher 120 is provided with an inlet 121 and an outlet 122. The first transmission shaft 141 is connected to the ball pusher 120 to drive the ball pusher 120 to rotate. When the ball pusher 120 rotates to the first position, the inlet 121 is opened. When the ball pusher 120 rotates to the second position, the inlet 121 is closed. The piston shaft 142 is connected to the ball outlet 113 or the outlet 122, and is used to open or close the passage between the ball outlet 113 and the outlet 122. The cleaning member 150 is arranged in the cleaning chamber 111. The cleaning member 150 and the cylinder 110 can rotate relative to each other to clean the gas lift ball 210. When the gas lift ball 210 is in the cleaning state, the inlet 121 of the ball pusher 120 is closed, and the piston shaft 142 closes the passage between the ball outlet 113 and the outlet 122. When the gas lift ball 210 is in the cleaning state, the inlet 121 is opened, and the piston shaft 142 opens the passage between the ball outlet 113 and the outlet 122. The gas lift ball 210 enters the inlet 121 of the ball pusher 120 and reaches the ball outlet 113 through the outlet 122.

[0056] It can be understood that the piston shaft 142 can be connected to the outlet 122 of the ball pusher 120 to block the outlet 122 and cut off the passage between the outlet 122 and the ball outlet 113. Alternatively, the piston shaft 142 can be connected to the ball outlet 113 to block the ball outlet 113 and cut off the passage between the outlet 122 and the ball outlet 113. Alternatively, the piston shaft 142 can block the outlet 122 and the ball outlet 113 of the ball pusher 120 at the same time. In this embodiment, a T-shaped three-way structure is formed at the ball outlet 113. The axis of the outlet 122 of the ball pusher 120 is consistent with the axis of the piston shaft 142. The ball outlet 113 is connected to the ball outlet tube 117. The axis of the ball outlet 113 and the axis of the piston shaft 142 are perpendicular to each other.

[0057] The piston shaft 142 can be driven by an electric push rod or a linear cylinder. Figure 2 In the position shown, the piston shaft 142 moves to the right to the limit position, which can block the outlet 122 of the ball pusher 120 and close the ball outlet 113 at the same time. The piston shaft 142 moves to the left to the limit position, which can open the outlet 122 of the ball pusher 120 and avoid the ball outlet 113, so that the outlet 122 of the ball pusher 120 and the ball outlet 113 are connected. It should be noted that when the piston shaft 142 blocks the outlet 122 of the ball pusher 120, the piston shaft 142 and the ball pusher 120 are sealed and connected to prevent the liquid, impurities, etc. in the cleaning chamber 111 from flowing into the ball outlet 113.

[0058] The goal inlet 112 is connected to a goal pipe 116 for receiving the gas lift ball 210 from the separation device 220. The ball outlet 113 is connected to a ball outlet pipe 117 for transporting the gas lift ball 210 to the ball serving device 230 for standby. The liquid inlet 114 is connected to a liquid inlet pipe 118 for injecting cleaning liquid into the cleaning chamber 111. The liquid outlet 115 is connected to a drain pipe 119 for draining dirty water after cleaning. Optionally, the goal inlet 112, the ball outlet 113, the liquid inlet 114 and the liquid outlet 115 are respectively connected to valves 101 for controlling the opening and closing of each port. During the cleaning process, each port is in a closed state.

[0059] Combination Figures 4 to 5 The ball pusher 120 includes an isolation tank 123, a first turntable 128 and a second turntable 129. An inlet 121 and an outlet 122 are provided on the isolation tank 123. The first turntable 128 and the second turntable 129 are respectively connected to the first transmission shaft 141, and the first turntable 128 and the second turntable 129 can rotate relative to the isolation tank 123. The first turntable 128 is used to open or close the inlet 121, and the outlet 122 is used to selectively communicate with the ball outlet 113. The first transmission shaft 141 rotates, which can drive the first turntable 128 and the second turntable 129 to rotate synchronously, and the isolation tank 123 does not rotate. The first turntable 128 and the second turntable 129 rotate around the axis of the first transmission shaft 141. In this embodiment, the first transmission shaft 141 is driven by a motor.

[0060] Optionally, the isolation tank 123 includes a first partition plate 124, a second partition plate 125 and a side plate 127, and the first partition plate 124 and the second partition plate 125 are connected at both ends of the side plate 127. The first partition plate 124, the second partition plate 125 and the side plate 127 form an isolation chamber. The side plate 127 is an annular side plate 127. The cross-sectional profile of the side plate 127 can be a quadrilateral, a triangle, a circle, an ellipse or any other shape. An inlet 121 is provided on the first partition plate 124, and an outlet 122 is provided on the side plate 127. The first turntable 128 is provided on the side of the first partition plate 124 away from the second partition plate 125. The second turntable 129 is provided on the side of the second partition plate 125 close to the first partition plate 124.

[0061] During the cleaning process, the first turntable 128 blocks the entrance 121 to prevent the air-lifting ball 210 from entering the interior of the ball pusher 120. After the cleaning is completed, the first turntable 128 rotates to open the entrance 121. The air-lifting ball 210 falls into the isolation chamber from the entrance 121. Under the rotation of the second turntable 129, the air-lifting ball 210 in the isolation chamber is pushed to the exit 122 and enters the ball outlet 113 in turn. It can be understood that since the ball outlet 113 is below the exit 122 of the ball pusher 120, and the distance between the two in the horizontal direction is very close. For example, the distance between the exit 122 and the ball outlet 113 in the horizontal direction is less than the diameter of an air-lifting ball 210. In this way, the air-lifting ball 210 will naturally fall into the ball outlet 113 after reaching the exit 122, and enter the ball serving device 230 along the ball outlet pipe 117 for standby use.

[0062] Optionally, a limiting baffle 132 is provided in the isolation chamber, and the limiting baffle 132 forms a ball-pushing channel 133 for connecting the inlet 121 and the outlet 122. The setting of the limiting baffle 132 can shorten the path of the air-lifting ball 210 from the inlet 121 to the outlet 122, and guide the air-lifting ball 210 in the isolation chamber. The inlet 121 and the ball-pushing channel 133 are arranged opposite to each other, so that the air-lifting ball 210 can directly fall from the inlet 121 into the ball-pushing channel 133. The rotation of the second turntable 129 assists in pushing the air-lifting ball 210 in the ball-pushing channel 133 to the outlet 122. In this embodiment, the limiting baffle 132 adopts a U-shaped plate. The two ends of the U-shaped plate are respectively connected to the side plate 127, and the two ends of the U-shaped plate are respectively located on both sides of the outlet 122. In this way, it can be ensured that the air-lifting ball 210 directly enters the outlet 122 of the side plate 127 after entering the ball-pushing channel 133 from the inlet 121. The limit baffle 132 is fixedly connected to the side plate 127. There is a certain distance between the limit baffle 132 and the second rotating disk 129. In this way, the second rotating disk 129 will not interfere with the limit baffle 132 when rotating. Of course, in some other embodiments, the limit baffle 132 can also be in other shapes. Such as semicircular, V-shaped or fan-shaped. Optionally, the limit baffle 132 can also be connected to the first partition 124, which also has similar technical effects.

[0063] Optionally, the first partition plate 124 and the second partition plate 125 are respectively provided with through holes (not shown) for the first transmission shaft 141 to pass through. In this way, the first transmission shaft 141 is conveniently fixedly connected to the first rotating disk 128 and the second rotating disk 129. When the first transmission shaft 141 rotates, the first rotating disk 128 and the second rotating disk 129 can rotate synchronously, while the first partition plate 124 and the second partition plate 125 are fixed.

[0064] Optionally, the first partition 124 and the second partition 125 are provided with leakage holes 126, respectively. This facilitates the discharge of dirty water after cleaning from the bottom of the ball pusher 120. The size of the leakage holes 126 should be designed to prevent the air lift ball 210 from passing through. The shape, number and distribution of the leakage holes 126 can be flexibly set according to actual conditions. In this embodiment, the leakage holes 126 are in the shape of long strips, and are centered on the center of the first rotating disk 128 or the second rotating disk 129, and are radially distributed outward.

[0065] The shapes and sizes of the first turntable 128 and the second turntable 129 can be flexibly designed. As long as the first turntable 128 can block or open the entrance 121. The structure of the first turntable 128 and the structure of the second turntable 129 can be the same or different. Optionally, the first turntable 128 and the second turntable 129 are respectively provided with a ball pushing portion 130, and the edge of the ball pushing portion 130 is provided with an arc profile 131 adapted to the diameter of the air lift ball 210. This is conducive to better pushing the air lift ball 210 from the first partition 124 to the entrance 121, thereby improving the ball pushing efficiency. Optionally, the number of the ball pushing portions 130 can be one or more. If multiple ball pushing portions 130 are designed, the multiple ball pushing portions 130 are arranged at intervals along the circumference of the first turntable 128 or the second turntable 129, which is conducive to improving the ball pushing efficiency.

[0066] In this embodiment, the first rotating disk 128 and the second rotating disk 129 are three-claw rotating disks, that is, they are respectively provided with three ball pushing parts 130. The number of the ball pushing parts 130 can be one, two, four, five, six or more.

[0067] Optionally, along the axial direction of the cylinder 110, there is a preset distance between the isolation tank 123 and the bottom of the cleaning chamber 111. In other words, the ball pusher 120 is suspended in the cleaning chamber 111. Since most of the dirt and impurities after cleaning will be deposited at the bottom of the cleaning chamber 111. This embodiment is configured so that the air lift ball 210 will not contact the dirt and impurities at the bottom of the cleaning chamber 111. And the outlet 122 of the ball pusher 120 is provided on the side plate 127, and is also at a certain distance from the bottom of the cleaning chamber 111. That is, during the entire cleaning process, the air lift ball 210 will not contact the bottom of the cleaning chamber 111 from beginning to end, which can ensure that the air lift ball 210 is cleaner after cleaning and is not contaminated again. Improve the cleaning quality and efficiency of the cleaning device 100.

[0068] Optionally, the cleaning member 150 includes a first cleaning brush 151. The cleaning device 100 also includes a second transmission shaft 155, which is in transmission connection with the first cleaning brush 151, driving the first cleaning brush 151 to move in the cleaning chamber 111. The movement of the first cleaning brush 151 includes but is not limited to movement, rotation, or a combination thereof. During the movement, the first cleaning brush 151 contacts the surface of the air lift ball 210 to remove dirt on the surface of the air lift ball 210.

[0069] In this embodiment, the first cleaning brush 151 includes a bracket 152, a brush strip 153 and bristles 154. The bracket 152 is provided with a plurality of brush strips 153 distributed along the axial direction of the cylinder 110. The brush strips 153 are densely covered with a plurality of bristles 154. The first cleaning brush 151 is located above the ball pusher 120, that is, located on the side of the ball pusher 120 away from the bottom of the cleaning chamber 111. The bracket 152 is fixedly connected to the second transmission shaft 155, and the brush strip 153 and the bracket 152 are detachably connected. The second transmission shaft 155 rotates under the drive of the motor, driving the bracket 152 and the brush strip 153 to rotate as a whole. The brush strip 153 is convenient to disassemble and replace after being used for a period of time.

[0070] Optionally, the cleaning member 150 further includes a second cleaning brush 156. A conical bottom plate 157 is provided in the cylinder 110 and is located above the ball pusher 120. The large end of the bottom plate 157 is connected to the inner wall of the cylinder 110, and the small end of the bottom plate 157 is connected to the ball pusher 120. The second cleaning brush 156 is provided on the bottom plate 157. The bottom plate 157 is relatively arranged at the outer periphery of the ball pusher 120. The second cleaning brush 156 is distributed along the circumferential direction on the bottom plate 157, and can further contact with the air lift ball 210 to clean the surface of the air lift ball 210. The cleaning efficiency is improved, and the cleaning is more thorough and cleaner.

[0071] Optionally, the cylinder 110 includes an upper sealing plate 161, a lower sealing plate 162 and a tank body 164, the upper sealing plate 161 and the lower sealing plate 162 are respectively arranged at the two ends of the tank body 164, and the upper sealing plate 161, the lower sealing plate 162 and the tank body 164 are connected to form a cleaning chamber 111. The annular edge of the small end of the chassis 157 is connected to the annular edge of the first partition 124. The annular edge of the large end of the chassis 157 is connected to the annular inner wall of the tank body 164. It can be understood that the diameter of the small end of the chassis 157 is adapted to the diameter of the first partition 124. The diameter of the large end of the chassis 157 is adapted to the inner diameter of the tank body 164. During the cleaning process, the air lift ball 210 is concentrated in the space surrounded by the first partition 124, the chassis 157, the tank body 164 and the upper sealing plate 161.

[0072] The surface of one side of the lower sealing plate 162 close to the cleaning chamber 111 is inclined relative to the horizontal plane to form a guide slope 163. The liquid outlet 115 is arranged at the lowest point of the guide slope 163. This is conducive to more thorough discharge of sewage and impurities and avoids dirt from being deposited on the lower sealing plate 162.

[0073] Optionally, a heating and heat preservation layer (not shown) is provided outside the cylinder 110. The heating and heat preservation layer includes a heating unit, such as heating by a resistance wire. In this way, the cleaning liquid in the cleaning chamber 111 can be maintained within a suitable temperature range. The cleaning liquid at a suitable temperature is conducive to removing dirt such as oil and wax on the surface of the gas lift ball 210, which is conducive to more thorough removal of dirt on the surface of the gas lift ball 210 and cleaner cleaning.

[0074] Optionally, a turbidity detector 165 is provided in the cleaning chamber 111 to detect whether the air lift ball 210 is clean. The turbidity detector 165 is used to detect the turbidity of the cleaning liquid after cleaning. If the turbidity reaches a preset value and meets the requirements, it is determined that the air lift ball 210 has been cleaned. If the turbidity does not reach the preset value, continue to change the water for cleaning.

[0075] Optionally, a temperature detector is provided in the cleaning chamber 111, and the temperature detector is used to detect the temperature of the cleaning liquid. If the temperature is too low, the heating unit in the heating and insulation layer is started. If the temperature reaches a preset temperature, the heating is stopped.

[0076] A counter is provided in the cleaning chamber 111, or a counter is provided at the ball pipe 116. When the number of the air lift balls 210 entering the cleaning chamber 111 reaches a preset value, a centralized cleaning is started.

[0077] The specific working principle of the cleaning device 100 is as follows:

[0078] After the gas lift ball 210 is separated from the oil by the separation device 220, it enters the cleaning chamber 111 of the cleaning device 100 through the ball tube 116. When the number of gas lift balls 210 accumulates to a preset number, they are cleaned uniformly. At this time, the valve 101 at the ball tube 116, the valve 101 at the liquid outlet 115, and the valve 101 at the ball outlet 113 are closed, and the piston shaft 142 closes the outlet 122 of the ball pusher 120. The first rotating disk 128 closes the inlet 121 of the ball pusher 120. The valve 101 of the liquid inlet 114 is opened, and the cleaning liquid is injected into the cleaning chamber 111. The motor connected to the second transmission shaft 155 is started to drive the first cleaning brush 151 to rotate and stir the cleaning liquid. While the gas lift ball 210 rotates with the cleaning liquid in the cleaning chamber 111, it can also contact the bristles 154 on the first cleaning brush 151 and the second cleaning brush 156, so that the cleaning is more thorough. After cleaning for a period of time, open the valve 101 at the liquid outlet 115 to discharge the sewage. Open the valve 101 of the liquid inlet 114 again, and inject the cleaning liquid into the cleaning chamber 111 for the second round of cleaning. After multiple rounds of cleaning, the turbidity of the cleaning liquid is detected in real time by the turbidity detector 165, and the data is sent to the control unit. When the turbidity reaches the preset value and meets the requirements, the control unit determines that the air lift ball 210 has been cleaned. Open the valve 101 at the liquid outlet 115 and wait for all the sewage to be discharged. Then the piston shaft 142 withdraws from the outlet 122 of the ball pusher 120, so that the outlet 122 and the ball outlet 113 are connected. The valve 101 at the ball outlet pipe 117 is opened. Start the motor connected to the first transmission shaft 141, and the first turntable 128 opens the inlet 121 of the ball pusher 120. The air-lifting ball 210 passes from the cleaning chamber 111 through the inlet 121, the ball pushing channel 133, the outlet 122, the ball outlet 113, and enters the ball-launching device 230 from the ball outlet pipe 117 for use.

[0079] It can be understood that the rotation of the first rotating disk 128 and the second rotating disk 129 can assist the gas lift ball 210 to quickly enter the ball outlet pipe 117 from the cleaning chamber 111. The rotation direction of the first rotating disk 128 and the second rotating disk 129 is not limited, and can be forward, reverse, or alternately forward and reverse. Since the ball pusher 120 is suspended, solid impurities are prevented from entering the ball outlet pipe 117 and its downstream pipeline, reducing the wear of the components along the downstream pipeline, especially avoiding the wear of the valve, and improving the valve accuracy and service life.

[0080] Combination Figure 6 The embodiment of the utility model further provides a golf gas lift system 200, comprising a gas lift ball 210, a separation device 220, a ball serving device 230, a delivery pipeline 240 and the above-mentioned cleaning device 100. The separation device 220 is connected to the ball inlet 112 of the cleaning device 100, the ball outlet 113 of the cleaning device 100 is connected to the ball serving device 230, the ball serving device 230 puts the gas lift ball 210 into the delivery pipeline 240, and the separation device 220 is connected to the end of the delivery pipeline 240 away from the ball serving device 230.

[0081] In this embodiment, the delivery pipeline 240 is generally U-shaped. The ball-serving device 230 is connected to one end of the U-shaped pipeline. A one-way valve 241 is provided at the bottom of the U-shaped pipeline, and the one-way valve 241 is used to allow the oil in the formation to enter the U-shaped pipeline in one direction. The other end of the U-shaped pipeline extends upward to the ground and is connected to the separation device 220.

[0082] Three ball valves are installed at the connection between the ball launching device 230 and the U-shaped pipe, namely the first ball valve 231, the second ball valve 232 and the third ball valve 233. The first ball valve 231 and the third ball valve 233 are arranged at intervals, and both are located on the main road of the U-shaped pipe. The main road between the first ball valve 231 and the third ball valve 233 is connected to the gas injection pipe 234, and the second ball valve 232 is arranged on the gas injection pipe 234. When launching the ball, the first ball valve 231 is opened, the second ball valve 232 and the third ball valve 233 are closed, and the gas lift ball 210 in the ball launching device 230 falls into the U-shaped pipe, and only one gas lift ball 210 can be controlled to be launched each time. Then the first ball valve 231 is closed to isolate the pressure, and the second ball valve 232 is opened to allow the gas from the air compressor to enter the U-shaped pipe. Finally, the third ball valve 233 is opened, and the gas lift ball 210 is pushed by the gas of the air compressor to move along the U-shaped pipeline to the ground, and the oil in the pipeline is transported to the ground, completing a gas lift oil production process. After the oil and the gas lift ball 210 reach the ground, they enter the separation device 220 for separation, and the separated gas lift ball 210 enters the cleaning device 100 for cleaning. The cleaned gas lift ball 210 enters the ball serving device 230 for standby.

[0083] Optionally, a track 221 is provided in the separation device 220, and the gas lift ball 210 moves along the track 221 during the separation process. The track 221 is a hollow design. Since the separation device 220 has a pressure relief function, the pressure of the gas entering the separation device 220 is close to normal pressure at this time. After the oil enters the separation device 220, it falls under the action of gravity and enters the oil collection port at the bottom of the separation device 220. The gas lift ball 210 can be separated from the oil by moving along the track 221. The end of the track 221 is connected to the ball entry tube 116 of the cleaning device 100, so that the separated gas lift ball 210 can smoothly enter the cleaning chamber 111.

[0084] Optionally, a heating assembly is provided on the track 221 of the separation device 220. The track 221 can be heated, and the heating temperature can be adjusted and controlled. In this way, the oil attached to the surface of the gas lift ball 210 is not easy to stick to the track 221. The track 221 can be a steel rail.

[0085] Combination Figure 7 and Figure 8 Optionally, a first detection sensor 211 is provided in the gas lift ball 210. The golf gas lift system 200 further includes a control unit, and the first detection sensor 211 is in communication connection with the control unit. The first detection sensor 211 includes but is not limited to any one or more of a temperature sensor and a pressure sensor. In this embodiment, the first detection sensor 211 includes a temperature sensor and a pressure sensor. In other embodiments, other types of detection sensors may be added according to actual needs, which are not specifically limited here.

[0086] A power supply 212 and a transmission unit 213 are provided in the gas lift ball 210. The power supply 212 is electrically connected to the first detection sensor 211 and the transmission unit 213 respectively, and the first detection sensor 211 and the transmission unit 213 are electrically connected. The transmission unit 213 is connected to the control unit for communication. The power supply 212 is used to supply power to the first detection sensor 211 and the transmission unit 213. The transmission unit 213 can adopt a wireless data transmission module, such as a Bluetooth transmission method. The gas lift ball 210 collects temperature and pressure data at the bottom of the well in the underground transmission pipeline 240, and sends the temperature and pressure data to the control unit via Bluetooth after reaching the ground. The power supply 212 can be a battery. The battery and the first detection sensor 211 are both high temperature resistant models, compact in size, and highly shock resistant, which can realize data collection and storage, and transmit to the control unit via wireless methods such as Bluetooth.

[0087] Optionally, the surface of the air lift ball 210 is provided with elastic protrusions 214. The provision of the elastic protrusions 214 can improve the wear resistance of the air lift ball 210, reduce the friction resistance between the inner wall of the delivery pipe 240 and the air lift ball 210, and move more smoothly. At the same time, it can also reduce the leakage of liquid, and the oil production efficiency is higher. In addition, the provision of the elastic protrusions 214 can also have a certain cleaning effect on the inner wall of the delivery pipe 240, and scrape off the sand and other attachments on the inner wall of the delivery pipe 240. The number, shape, protrusion length, etc. of the elastic protrusions 214 can be flexibly set. For example, it is designed to be a long strip or similar to the structure of the bristles 154. In this embodiment, the elastic protrusions 214 are designed to be long whiskers, similar to rambutan with fluff, and can clean the pipe wall while moving in the delivery pipe 240 to prevent wax accumulation on the pipe wall. The elastic protrusions 214 can be made of soft rubber material.

[0088] It should be noted that, through the elastic protrusions 214 on the surface of the gas lift ball 210, the gap between the gas lift ball 210 and the inner wall of the delivery pipe 240 is zero during the upward movement, or the gas lift ball 210 and the delivery pipe 240 move under a preset friction resistance. In other words, the gas lift ball 210 can always be kept in close contact with the inner wall of the delivery pipe 240 in the upward state, so as to reduce oil leakage from the gap between the two and improve oil recovery efficiency.

[0089] Optionally, a second detection sensor is further included, and the second detection sensor is communicatively connected with the control unit. The second detection sensor is arranged in the stratum outside the delivery pipeline 240. Optionally, the second detection sensor can be arranged at or near the entrance of the oil in the stratum into the delivery pipeline 240. The second detection sensor is used to detect the temperature and pressure of the oil in the stratum in real time. The second detection sensor includes but is not limited to any one or more of a temperature sensor and a pressure sensor. Other types of detection sensors can also be added according to actual needs. The second detection sensor can be connected to the control unit on the ground through a cable to realize real-time data transmission and improve the control accuracy of the control unit.

[0090] Based on the collection of the above real-time data, it is beneficial to adjust the firing frequency, the injection pressure and the injection volume, so as to achieve real-time regulation, ensure the stability and controllability of the oil production process, and improve the oil well recovery rate.

[0091] It can be understood that the separation device 220, the cleaning device 100 and the ball-launching device 230 are all located on the ground, and the U-shaped pipe part of the conveying pipeline 240 is located below the ground. The control unit sets the ball-launching interval according to the measured bottom hole pressure and temperature, and controls the corresponding motor of the ball-launching device 230 to launch the ball according to the set time, and launches a gas lift ball 210 each time. The cleaning device 100 cleans the gas lift ball 210 to ensure that a clean gas lift ball 210 is launched each time, and prevents the mud and sand carried by the gas lift ball 210 from entering the ball valve to damage the valve core and thus affect the normal operation of the equipment. The cleaning process is fully automated and does not require manual intervention, with high cleaning efficiency and good cleaning effect.

[0092] In summary, the golf ball gas lift system 200 and cleaning device 100 provided by the embodiment of the utility model have the following beneficial effects, including:

[0093] The cleaning device 100 provided by the embodiment of the utility model has a cleaning part 150 in the cleaning chamber 111, which can clean the surface of the gas lift ball 210. During the cleaning process, the piston shaft 142 will close the ball outlet 113, and all the gas lift balls 210 will be concentrated in the cleaning chamber 111. After the cleaning is completed, the inlet 121 of the ball pusher 120 is opened, and the gas lift ball 210 is transferred to the ball outlet 113 by the ball pusher 120 to prepare for the next use. Since the gas lift ball 210 has been cleaned before use, the wear of the gas lift ball 210 and the parts along the pipeline can be reduced, thereby increasing the service life of the parts.

[0094] The golf gas lift system 200 provided in the embodiment of the utility model includes the above-mentioned cleaning device 100, and the cleaning device 100 is arranged between the separation device 220 and the serving device 230. After the cleaning device 100 cleans the separated gas lift ball 210, it enters the serving device 230 from the ball outlet 113 of the cleaning device 100 for standby. The cleaned gas lift ball 210 can reduce the wear of the components in the pipeline along the way and increase the service life of the components. The serving device 230 can control a single serve to avoid ball jamming and poor serve. The gas lift ball 210 can also clean the conveying pipeline 240, extend the service life of the entire system, and improve oil recovery efficiency.

[0095] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
