Description

Technical Field

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

[0002] Boosting can be used for the transportation and storage of natural gas. Gas lift is to inject high-pressure gas into the well to increase the pressure in the well, facilitating the collection of raw materials. Since the pressure levels required for boosting and gas lift are different, different compressors need to be used respectively for boosting and gas lift, and different equipment and processes need to be coordinated, resulting in a complex pipeline system, high construction costs, and great maintenance difficulties. Existing gas lift booster integrated machines achieve gas lift or boosting effects only by using a variety of the same compressors through pipeline cooperation. However, the current market situation is that most of the oil and gas field equipment uses motor-driven compressors. If there is no power grid area, a generator needs to be purchased separately, and the cost is too high. Currently, the gas lift booster integrated machine usually has only one intake pipeline and one outlet pipeline. Therefore, it cannot meet the gas lift requirements during the boosting operation, that is, gas lift and boosting cannot be carried out simultaneously. At the same time, during the process of extracting natural gas, due to the possible presence of a small amount of crude oil in the cracks in the well, the purity of natural gas is not high at the initial stage of extracting natural gas, resulting in poor gas production effect.

[0003] Therefore, the present application provides a combustion-driven circulating gas lift booster integrated machine to meet the requirements. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a combustion-driven circulating gas lift booster integrated machine. By setting a boosting exhaust system and a gas lift boosting system, the device can perform gas lift and boosting operations in the oil field, realizing dual functions in one machine. By setting a combustion-driven multi-stage compression system, efficient on-site scheduling of circulating gas lift boosting in oil and gas fields is achieved. At the same time, by setting a purification component, the natural gas in the well rises, thereby improving the purity of the extracted natural gas, so as to solve the problems of high use cost and poor effect of the existing gas lift booster integrated machine.

The natural gas after secondary compression in the gas collecting pipe 145 is input into the medium-sized vertical gas-liquid separator 153 through the fourth gas delivery pipe 151. After being compressed three times by the compressor 550 connected to the fifth gas delivery pipe 154, it is discharged into the gas lift exhaust main pipe 155 through the second branch outlet pipe 591. At this time, by closing the solenoid valve at the end of the gas lift exhaust main pipe 155 and opening the seventh solenoid valve 157, the natural gas in the gas lift exhaust main pipe 155 can be introduced into the supercharging exhaust main pipe 132 through the rotating gas pipe 156, and the natural gas after three-stage compression in the supercharging exhaust main pipe 132 can be collected.

[0031] In this embodiment, as Figures 26 to 28 shown, the gas lift supercharging system 200 is composed of a primary supercharging air intake assembly 210, a secondary supercharging air intake assembly 220, and a tertiary supercharging air intake assembly 230; The primary supercharging air intake assembly 210 includes a gas lift air intake pipe 211. A solenoid valve eight 212 is arranged on the gas lift air intake pipe 211. The end of the gas lift air intake pipe 211 is hermetically communicated with the input port of the medium-sized vertical gas-liquid separator 153. In the present invention, when the pressure in the well is not sufficient to press out the natural gas, nitrogen is pressed into the gas lift air intake pipe 211. At the same time, by opening the solenoid valve eight 212, the nitrogen can be introduced into the medium-sized vertical gas-liquid separator 153. After being compressed by the compressor 550 connected to the fifth gas delivery pipe 154, it is discharged into the gas lift exhaust main pipe 155 through the second branch outlet pipe 591. Thereafter, by opening the solenoid valve at the end of the gas lift exhaust main pipe 155, the nitrogen under primary pressure in the gas lift exhaust main pipe 155 can be discharged into the well for supercharging; The secondary supercharging intake assembly 220 includes an intake branch pipe 221.

The end of the intake branch pipe 221 is in sealed communication with 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 eight 212 is closed and the solenoid valve nine 222 is opened, and the nitrogen gas in the gas lift intake pipe 211 can be introduced into the small vertical gas-liquid separator 143. After being compressed by two groups of compressors 550, it is 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, and the second-stage pressurized nitrogen gas in the gas lift exhaust main pipe 155 can be discharged into the well for pressurization; The tertiary supercharging intake assembly 230 includes an intake branch pipe 231. The intake branch pipe 231 is in sealed communication with the gas lift intake pipe 211. A pressure valve 232 is provided on the intake branch pipe 231. The end of the intake branch pipe 231 is in sealed communication with the air supply pipe one 131. In the present invention, when the pressure in the well is lower than a certain threshold value, the pressure valve 232 automatically opens and the solenoid valve nine 222 closes, and the nitrogen gas in the gas lift intake pipe 211 can be introduced into the air supply pipe one 131 through the intake branch pipe 231. After being compressed by multiple groups of compressors 550, the solenoid valve at the end of the gas lift exhaust main pipe 155 is opened, and the third-stage pressurized nitrogen gas in the gas lift exhaust main pipe 155 can be discharged into the well for pressurization; The solenoid valve eight 212, the solenoid valve nine 222 and the pressure valve 232 are arranged in parallel, and the pressure valve 232 is in a sealed state under normal conditions. By controlling the closing of the solenoid valve eight 212, the solenoid valve nine 222 and the pressure valve 232, the purpose of controlling the gas lift pressurization system 200 can be achieved. In particular, when extracting natural gas in the well and 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 one 115 and opening the solenoid valve three 133, the natural gas compressed once in the pressurized exhaust main pipe 132 can be collected. At the same time, nitrogen gas is pressed into the gas lift intake pipe 211 and the solenoid valve eight 212 is opened. The solenoid valve at the end of the gas lift exhaust main pipe 155 is opened, and the first-stage pressurized nitrogen gas 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 synchronously to improve the pumping efficiency.

[0032] In this embodiment, as Figure 18 and Figure 19 shown, the sewage disposal system 300 includes a sewage main pipe 310. The sewage main pipe 310 is in communication with the bottoms 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; The pressure stabilizing system 400 includes a vent main pipe 410, which is connected to the tops of a large vertical gas-liquid separator 113, a small vertical gas-liquid separator 143, and a 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 (regulated through various different valve bodies), and realizes the regulation of air pressure 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.

[0033] In this embodiment, as Figure 2 shown, an air cooler 610 is fixedly installed at the top of the end of the base 600. The air cooler 610 is short for an air-cooled heat exchanger, which is one of the most widely used heat exchange equipment for condensation and cooling in petrochemical and oil and gas processing production. The air cooler 610 generally consists of main parts such as tube bundles, tube boxes, fans, louvers, and frameworks. The gas lift exhaust main pipe 155, the gas lift exhaust branch pipe 121, the pressurized exhaust branch pipe 114, and the pressurized exhaust main pipe 132 are all connected to the air cooler 610. In the present invention, the air cooler 610 can cool the gases output by the gas lift exhaust main pipe 155, the gas lift exhaust branch pipe 121, the pressurized exhaust branch pipe 114, and the pressurized exhaust main pipe 132, avoiding potential safety hazards caused by high temperatures.

[0034] 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, that is, there is no need for compression and collection. At this time, the natural gas in the well enters the large vertical gas-liquid separator 113 through the pressurized inlet pipe 111, and after being separated and filtered by the large vertical gas-liquid separator 113, it enters the pressurized exhaust branch pipe 114. Then, by opening the solenoid valve 115 on the pressurized exhaust branch pipe 114, the natural gas in the pressurized exhaust branch pipe 114 can be collected; As the natural gas in the well is discharged and collected, when the pressure of the discharged natural gas fails to reach the collection standard, the first electromagnetic 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 first gas supply pipe 131. After being compressed by the two groups of compressors 550, it is discharged into the pressurized exhaust main pipe 132 through the main outlet pipe 570. Then, by opening the third electromagnetic valve 133 on the pressurized exhaust main pipe 132, the natural gas compressed once in the pressurized exhaust main pipe 132 can be collected. Similarly, when the collection requirement is still not met after the first compression, the third electromagnetic valve 133 is closed and the fourth electromagnetic valve 142 is opened. The natural gas compressed once is sent into the small vertical gas-liquid separator 143 through the second gas supply pipe 141. After being compressed twice by the compressor 550 connected to the third gas supply pipe 144, it is discharged into the gas collecting pipe 145 through the first branch outlet pipe 581. At this time, by opening the fifth electromagnetic valve 146, the natural gas compressed twice in the gas collecting pipe 145 can be collected. When the collection requirement is still not met after the second compression, the fifth electromagnetic valve 146 is closed and the sixth electromagnetic valve 152 is opened. The natural gas compressed twice in the gas collecting pipe 145 is input into the medium vertical gas-liquid separator 153 through the fourth gas supply pipe 151. After being compressed three times by the compressor 550 connected to the fifth gas supply pipe 154, it is discharged into the gas lift exhaust main pipe 155 through the second branch outlet pipe 591. At this time, by closing the electromagnetic valve at the end of the gas lift exhaust main pipe 155 and opening the seventh electromagnetic valve 157, the natural gas in the gas lift exhaust main pipe 155 can be introduced into the pressurized exhaust main pipe 132 through the transfer gas pipe 156, and the natural gas compressed three times in the pressurized exhaust main pipe 132 can be collected; When the pressure in the well is insufficient to press out the natural gas, nitrogen is pressed into the gas lift inlet pipe 211. At the same time, by opening the eighth electromagnetic valve 212, the nitrogen can be introduced into the medium vertical gas-liquid separator 153. After being compressed by the compressor 550 connected to the fifth gas supply pipe 154, it is discharged into the gas lift exhaust main pipe 155 through the second branch outlet pipe 591. Then, by opening the electromagnetic valve at the end of the gas lift exhaust main pipe 155, the nitrogen compressed once in the gas lift exhaust main pipe 155 can be discharged into the well for pressurization. When the pressure in the well is too low, the eighth electromagnetic valve 212 is closed and the ninth electromagnetic valve 222 is opened. The nitrogen in the gas lift inlet pipe 211 can be introduced into the small vertical gas-liquid separator 143 and compressed by the two groups of compressors 550. Then, it is discharged into the gas lift exhaust main pipe 155 through the second branch outlet pipe 591. Then, by opening the electromagnetic valve at the end of the gas lift exhaust main pipe 155, the nitrogen compressed twice in the gas lift exhaust main pipe 155 can be discharged into the well for pressurization. Similarly, when the pressure in the well is lower than a certain threshold, the pressure valve 232 automatically opens and the ninth electromagnetic valve 222 is closed. The nitrogen in the gas lift inlet pipe 211 can be introduced into the first gas supply pipe 131 through the second intake branch pipe 231. After being compressed by multiple groups of compressors 550, by opening the electromagnetic valve at the end of the gas lift exhaust main pipe 155, the nitrogen compressed three times in the gas lift exhaust main pipe 155 can be discharged into the well for pressurization; Meanwhile, when extracting natural gas in 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 the first solenoid valve 115 and opening the third solenoid valve 133, the natural gas compressed once in the supercharging exhaust main pipe 132 can be collected. At the same time, nitrogen is pressed into the gas lift inlet pipe 211 and the eighth solenoid valve 212 is opened. By opening the solenoid valve at the end of the gas lift exhaust main pipe 155, the nitrogen gas compressed once in the gas lift exhaust main pipe 155 can be discharged into the well for supercharging. At this time, supercharging and gas lift can be carried out synchronously to improve the air extraction efficiency.
