Description

Technical Field

[0001] The present invention relates to the technical field of natural gas production, and in particular to a combustion-driven, circulating, gas-lift and pressurizing integrated machine. Background Art

[0002] Boosting can be used for the transportation and storage of natural gas, while gas lift increases the pressure inside the well by injecting high-pressure gas into the well to facilitate the collection of raw materials. Since boosting and gas lift require different pressure levels, they require different compressors, equipment, and processes, resulting in complex piping systems, high construction costs, and difficult maintenance.

[0003] Existing integrated gas lift and booster systems utilize pipelines and require multiple identical compressors to achieve gas lift or boosting effects. However, the current market situation is that most oil and gas field equipment uses electric motors to drive compressors. Areas without power grids require separate generators, which is costly.

[0004] Currently, gas lift and booster integrated machines usually have only one air inlet pipeline and one air outlet pipeline. Therefore, they cannot meet the gas lift requirements during the boosting operation, that is, they cannot perform gas lift and boosting simultaneously. At the same time, during the process of extracting natural gas, a small amount of crude oil may exist in the cracks in the well, resulting in low purity of natural gas in the early stage of extraction, resulting in poor gas production effect.

[0005] Therefore, this application provides a combustion-driven cycle gas lift and booster integrated machine to meet the needs. Summary of the Invention

By setting up a pressurized exhaust system and a gas lift and pressurization system, the device can perform gas lift and pressurization operations in the oil field, realizing dual-purpose use of one machine. By setting up a fuel-driven multi-stage compression system, efficient on-site scheduling of circulating gas lift and pressurization in the oil and gas field can be achieved.

In the present invention, when the collection demand is still not met after the first compression, the solenoid valve three 133 is closed and the solenoid valve four 142 is opened to send the natural gas compressed once into the small vertical gas-liquid separator 143 through the air supply pipe two 141, and then compressed for the second time by the compressor 550 connected to the air supply pipe three 144, and then discharged into the gas collecting pipe 145 through the branch outlet pipe one 581. At this time, the solenoid valve five 146 is opened to collect the natural gas compressed for the second time in the gas collecting pipe 145.

[0074] In this embodiment, if Figure 25As shown, the three-stage pressurized exhaust assembly 150 includes a medium-sized vertical gas-liquid separator 153, which is fixedly connected to the base 600. The bottom input end of the medium-sized vertical gas-liquid separator 153 is sealed and fixedly connected to the air supply pipe 4 151, and the other end of the air supply pipe 4 151 is connected to the inside of the gas collection pipe 145. The air supply pipe 4 151 is provided with a solenoid valve 6 152, and the solenoid valve 6 152 is provided in parallel with the solenoid valve 5 146. The output end of the medium-sized vertical gas-liquid separator 153 is sealed and fixedly connected to the air supply pipe 5 154, and the other end of the air supply pipe 5 154 is sealed and connected to the branch inlet pipe 2 590. The output end of the branch outlet pipe 2 591 is sealed and fixedly connected to the gas lift exhaust main pipe 155. The end of the gas lift exhaust main pipe 155 is provided with a solenoid valve. The middle part of the gas lift exhaust main pipe 155 is sealed and connected to the transfer pipe 156, and the other pipe of the transfer pipe 156 is connected to the other pipe of the transfer pipe 156. The port is connected to the boost exhaust main pipe 132, and a solenoid valve seven 157 is provided in the middle of the gas transfer pipe 156. In the present invention, when the natural gas after secondary compression still does not meet the pressure collection requirement, the solenoid valve five 146 is closed and the solenoid valve six 152 is opened, and the secondary compressed natural gas in the gas collection pipe 145 is input into the medium-sized vertical gas-liquid separator 153 through the gas supply pipe four 151, and then compressed three times by the compressor 550 connected to the gas supply pipe five 154, and then discharged into the gas lift exhaust main pipe 155 through the branch outlet pipe two 591. At this time, by closing the solenoid valve at the end of the gas lift exhaust main pipe 155 and opening the solenoid valve seven 157, the natural gas in the gas lift exhaust main pipe 155 can be introduced into the boost exhaust main pipe 132 through the gas transfer pipe 156, so that the natural gas that has been compressed three times in the boost exhaust main pipe 132 can be collected.

[0075] In this embodiment, if Figures 26 to 28 As shown, the gas lift pressurization system 200 is composed of a first-stage pressurization air intake assembly 210, a second-stage pressurization air intake assembly 220 and a third-stage pressurization air intake assembly 230;

[0076] The first-stage pressurized air intake assembly 210 includes a gas lift air intake pipe 211, on which a solenoid valve eight 212 is provided. The end of the gas lift air intake pipe 211 is sealed and connected to the input port of the medium-sized vertical gas-liquid separator 153. In the present invention, when the pressure in the well is insufficient to pressurize the natural gas, nitrogen is pressed into the gas lift air intake pipe 211. At the same time, the solenoid valve eight 212 is opened to allow the nitrogen to pass into the medium-sized vertical gas-liquid separator 153. The nitrogen is then compressed by the compressor 550 connected to the air supply pipe five 154 and discharged into the gas lift exhaust main pipe 155 through the branch outlet pipe two 591. Thereafter, the solenoid valve at the end of the gas lift exhaust main pipe 155 is opened to discharge the pressurized nitrogen in the gas lift exhaust main pipe 155 into the well for pressurization.

[0077] The two-stage pressurized air intake assembly 220 includes an air intake branch pipe 1 221, which is sealed and connected to the gas lift air intake pipe 211. The air intake branch pipe 1 221 is provided with a solenoid valve 9 222. The end of the air intake branch pipe 1 221 is sealed and connected to the input port of the small vertical gas-liquid separator 143. In the present invention, when the pressure in the well is too low, the solenoid valve 8 212 is closed and the solenoid valve 9 222 is opened. The nitrogen in the gas lift air intake pipe 211 can be introduced into the small vertical gas-liquid separator 143, and after being compressed by the two sets of compressors 550, it is discharged into the gas lift exhaust main pipe 155 through the branch outlet pipe 2 591. Thereafter, the solenoid valve at the end of the gas lift exhaust main pipe 155 is opened to discharge the secondary pressure nitrogen in the gas lift exhaust main pipe 155 into the well for pressurization.

[0078] The three-stage pressurized air intake assembly 230 includes a second air intake branch pipe 231, which is sealed and connected to the gas lift air intake pipe 211. The second air intake branch pipe 231 is provided with a pressure valve 232, and the end of the second air intake branch pipe 231 is sealed and connected to the first air supply pipe 131. In the present invention, when the pressure in the well is lower than a certain threshold, the pressure valve 232 automatically opens and the solenoid valve 9 222 closes, allowing the nitrogen in the gas lift air intake pipe 211 to be introduced into the first air supply pipe 131 through the second air intake branch pipe 231. After being compressed by multiple sets of compressors 550, the solenoid valve at the end of the gas lift exhaust main pipe 155 is opened, and the triple-pressure nitrogen in the gas lift exhaust main pipe 155 can be discharged into the well for pressurization.

[0079] Solenoid valve eight 212, solenoid valve nine 222 and pressure valve 232 are arranged in parallel, and pressure valve 232 is in a sealed state under normal circumstances. By regulating the closing of solenoid valve eight 212, solenoid valve nine 222 and pressure valve 232, the purpose of regulating the gas lift boosting system 200 can be achieved. In particular, when extracting natural gas from the well, when the pressure in the well and the pressure of the discharged natural gas decrease due to the continuous discharge of natural gas, by closing solenoid valve one 115 and opening solenoid valve three 133, the natural gas in the boosting and exhaust main pipe 132 that has been compressed once can be collected, and at the same time, nitrogen is pressed into the gas lift air inlet pipe 211 and solenoid valve eight 212 is opened. By opening the solenoid valve at the end of the gas lift exhaust main pipe 155, the pressurized nitrogen in the gas lift exhaust main pipe 155 can be discharged into the well for boosting. At this time, boosting and gas lifting can be carried out simultaneously, thereby improving the gas extraction efficiency.

[0080] In this embodiment, if Figure 18 and Figure 19 As shown, the sewage discharge system 300 includes a sewage main pipe 310, which is connected to the bottom of the large vertical gas-liquid separator 113, the small vertical gas-liquid separator 143, and the medium vertical gas-liquid separator 153. The sewage main pipe 310 can discharge the liquid and other impurities inside the large vertical gas-liquid separator 113, the small vertical gas-liquid separator 143, and the medium vertical gas-liquid separator 153;

[0081] The pressure stabilizing system 400 includes a vent main pipe 410, which is connected to the top of the large vertical gas-liquid separator 113, the small vertical gas-liquid separator 143, and the medium vertical gas-liquid separator 153. The vent main pipe 410 can regulate the air pressure inside the large vertical gas-liquid separator 113, the small vertical gas-liquid separator 143, and the medium vertical gas-liquid separator 153 (through various different valve bodies) and achieve air pressure regulation by discharging the air inside the large vertical gas-liquid separator 113, the small vertical gas-liquid separator 143, and the medium vertical gas-liquid separator 153.

[0082] In this embodiment, if Figure 2 As shown, an air cooler 610 is fixedly installed on the top end of the base 600. The air cooler 610 is the abbreviation of air cooler. It is a heat exchange equipment most widely used for condensation and cooling in petrochemical and oil and gas processing production. The air cooler 610 is generally composed of main parts such as tube bundles, tube boxes, fans, louvers and frames. The gas lift exhaust main pipe 155, the gas lift exhaust branch pipe 121, the boost exhaust branch pipe 114 and the boost exhaust main pipe 132 are all connected to the air cooler 610. In the present invention, the air cooler 610 can cool the gas output from the gas lift exhaust main pipe 155, the gas lift exhaust branch pipe 121, the boost exhaust branch pipe 114 and the boost exhaust main pipe 132 to avoid safety hazards caused by high temperature.

[0083] The working principle of the technical solution provided by the present invention is as follows: when the natural gas pressure in the well is too high, compression and collection are no longer necessary. At this time, the natural gas in the well enters the large vertical gas-liquid separator 113 through the booster intake pipe 111, and after separation and filtration in the large vertical gas-liquid separator 113, enters the booster exhaust branch pipe 114. Thereafter, the solenoid valve 115 on the booster exhaust branch pipe 114 is opened to collect the natural gas in the booster exhaust branch pipe 114.

[0084] As the natural gas in the well is discharged and collected, when the pressure of the discharged natural gas does not meet the collection standard, the solenoid valve 115 is closed. At this time, the natural gas separated and filtered by the large vertical gas-liquid separator 113 enters the main inlet pipe 560 through the air supply pipe 131, and is compressed by the two sets of compressors 550, and is discharged into the boost exhaust main pipe 132 through the main outlet pipe 570. Thereafter, the solenoid valve 3 133 on the boost exhaust main pipe 132 can be opened to collect the natural gas that has been compressed once in the boost exhaust main pipe 132. Similarly, when the collection demand is still not met after the first compression, the solenoid valve 3 133 is closed and the solenoid valve 4 142 is opened to send the natural gas that has been compressed once into the small vertical gas-liquid separator 143 through the air supply pipe 2 141, and then compressed for the second time by the compressor 550 connected to the air supply pipe 3 144, and then discharged by the branch valve 570. The outlet pipe 1 581 is discharged into the gas manifold 145. At this time, the solenoid valve 5 146 is opened to collect the natural gas in the gas manifold 145 after secondary compression. If the collection demand is still not met after secondary compression, the solenoid valve 5 146 is closed and the solenoid valve 6 152 is opened to input the secondary compressed natural gas in the gas manifold 145 into the medium-sized vertical gas-liquid separator 153 through the gas supply pipe 4 151. After being compressed three times by the compressor 550 connected to the gas supply pipe 5 154, it is discharged into the gas lift exhaust main pipe 155 through the branch outlet pipe 2 591. At this time, by closing the solenoid valve at the end of the gas lift exhaust main pipe 155 and opening the solenoid valve 7 157, the natural gas in the gas lift exhaust main pipe 155 can be introduced into the boost exhaust main pipe 132 through the gas transfer pipe 156, so that the natural gas in the boost exhaust main pipe 132 after tertiary compression can be collected.

[0085] When the pressure in the well is not enough to press out the natural gas, nitrogen is pressed into the gas lift inlet pipe 211, and at the same time, the solenoid valve eight 212 is opened to allow the nitrogen to be introduced into the medium-sized vertical gas-liquid separator 153, and then compressed by the compressor 550 connected to the gas supply pipe five 154, and then discharged into the gas lift exhaust main pipe 155 through the branch outlet pipe two 591. Thereafter, the solenoid valve at the end of the gas lift exhaust main pipe 155 is opened to discharge the pressurized nitrogen in the gas lift exhaust main pipe 155 into the well for pressurization. When the pressure in the well is too low, the solenoid valve eight 212 is closed and the solenoid valve nine 222 is opened to allow the nitrogen in the gas lift inlet pipe 211 to be introduced into the small vertical gas-liquid separator 143, and After being compressed by the two sets of compressors 550, the nitrogen is discharged into the gas lift exhaust main pipe 155 through the second branch outlet pipe 591. Thereafter, the solenoid valve at the end of the gas lift exhaust main pipe 155 is opened to discharge the second-pressure nitrogen in the gas lift exhaust main pipe 155 into the well for pressurization. Similarly, when the pressure in the well is lower than a certain threshold, the pressure valve 232 is automatically opened and the solenoid valve nine 222 is closed, and the nitrogen in the gas lift intake pipe 211 can be introduced into the gas supply pipe 1 131 through the second intake branch pipe 231. After being compressed by multiple sets of compressors 550, the solenoid valve at the end of the gas lift exhaust main pipe 155 is opened to discharge the third-pressure nitrogen in the gas lift exhaust main pipe 155 into the well for pressurization.

[0086] At the same time, when extracting natural gas from the well, the pressure in the well and the pressure of the discharged natural gas decrease due to the continuous discharge of natural gas. By closing the solenoid valve 115 and opening the solenoid valve 3 133, the natural gas compressed once in the pressurized exhaust main pipe 132 can be collected. At the same time, nitrogen is pressed into the gas lift inlet pipe 211 and the solenoid valve 8 212 is opened. By opening the solenoid valve at the end of the gas lift exhaust main pipe 155, the pressurized nitrogen in the gas lift exhaust main pipe 155 can be discharged into the well for pressurization. At this time, pressurization and gas lift can be carried out simultaneously, thereby improving the gas extraction efficiency.
