[0028] In order to make the technical problems, technical solutions and beneficial effects of the present application more clear, the present application will be described in detail with reference to the drawings. The drawing is a simplified schematic diagram, which only schematically illustrates the basic structure of the present application, and thus only shows the components related to the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0029] Reference Figure 1 As shown in the drawing, the present application provides a gas-liquid mixed delivery device 100, which comprises a first container 10, a second container 20 communicating with the first container 10, and a delivery assembly 30 arranged between the first container 10 and the second container 20. The first container 10 and the second container 20 are both communicated with an input end 200 through an input pipeline 40, so as to deliver gas-liquid mixed fluid into the first container 10 or the second container 20. Moreover, the first container 10 and the second container 20 are both communicated with an output end 300 through an output pipeline 50, so as to deliver the gas-liquid mixed fluid in the first container 10 or the second container 20 to the output end 300. The delivery assembly 30 is used to deliver driving liquid from the first container 10 into the second container 20, or deliver driving liquid from the second container 20 into the first container 10.

[0030] In some embodiments, when the input end 200 delivers the gas-liquid mixed fluid into the first container 10 through the input pipeline 40, the delivery assembly 30 delivers the driving liquid in the second container 20 into the first container 10, so as to deliver the gas-liquid mixed fluid entering the first container 10 to the output end 300 through the output pipeline 50. When the input end 200 delivers the gas-liquid mixed fluid into the second container 20 through the input pipeline 40, the delivery assembly 30 delivers the driving liquid in the first container 10 into the second container 20, so as to deliver the gas-liquid mixed fluid entering the second container 20 to the output end 300 through the output pipeline 50. In this way, the delivery of the gas-liquid mixed fluid is realized.

[0031] In some embodiments, the first container 10 and / or the second container 20 is provided with an injection pipe 101 for injecting driving liquid into the first container 10 and / or the second container 20. The driving liquid can be liquid or solution such as water or oil, which is mainly selected according to the composition of the gas-liquid mixed fluid to be delivered.

[0032] It should be understood that the input end 200 refers to the source of the gas-liquid mixed fluid, and the output end 300 refers to the destination of the gas-liquid mixed fluid.

[0033] In some embodiments, the input end 200 can be an oil and gas well in an oil and gas field, the output end 300 can be a terminal processing station, and the gas-liquid mixed fluid is produced fluid obtained from the oil and gas well. The produced fluid includes crude oil, water and natural gas.

[0034] In other embodiments, the input end 200 and the output end 300 can be oil and gas processing stations such as metering stations, transfer stations or gas gathering stations, or processing equipment in these oil and gas processing stations. The gas-liquid mixed conveying device 100 is used for oil and gas conveying between these oil and gas processing stations or processing equipment. Similarly, the gas-liquid mixed conveying device 100 can also be used for mixed conveying of oil and / or water and gas between chemical production equipment. By adding an absorbent to the driving liquid, specific liquid components or gas components can be removed during conveying, thereby reducing production steps or impurity removal steps.

[0035] In combination Figure 1 As shown, in some embodiments, the conveying assembly 30 includes a first conveying pump 31 in communication with the first container 10, a second conveying pump 32 in communication with the second container 20, and a driving member 33 for operating the first conveying pump 31 or the second conveying pump 32. The driving member 33 is configured to be engaged with a pump shaft of the first conveying pump 31 or the second conveying pump 32 to drive the first conveying pump 31 or the second conveying pump 32 to operate, so that the driving liquid can flow between the first container 10 and the second container 20.

[0036] In some embodiments, the first conveying pump 31 directly communicates with the lower part of the first container 10 and the second container 20, so that the first conveying pump 31 directly conveys the driving liquid in the first container 10 into the second container 20. Similarly, the second conveying pump 32 directly communicates with the lower part of the first container 10 and the second container 20, so that the second conveying pump 32 directly conveys the driving liquid in the second container 20 into the first container 10.

[0037] In some preferred embodiments, the first delivery pump 31 is in communication with the second delivery pump 32 through the communication pipe 34. During the process in which the first delivery pump 31 delivers the driving liquid in the first container 10 to the second container 20, the driving liquid can flow into the second delivery pump 32 through the communication pipe 34 so as to flush the impeller in the second delivery pump 32. Similarly, during the process in which the second delivery pump 32 delivers the driving liquid in the second container 20 to the first container 10, the driving liquid can flow into the first delivery pump 31 through the communication pipe 34 so as to flush the impeller in the first delivery pump 31. In this way, even if the sand, sludge and other solids contained in the gas-liquid mixed fluid precipitate in the driving liquid, these solids are difficult to adhere to the impellers of the first delivery pump 31 and the second delivery pump 32 for a long time, thereby effectively reducing the maintenance frequency of the first delivery pump 31 and the second delivery pump 32 and prolonging the service life of the first delivery pump 31 and the second delivery pump 32.

[0038] In the present embodiment, the driving member 33 is a double-output motor including a first output shaft 331 and a second output shaft 332. The double-output motor can output power to the outside through the first output shaft 331 and the second output shaft 332. The first output shaft 331 is connected to the pump shaft of the first delivery pump 31 through a first clutch 333, so that the first output shaft 331 can be engaged with or separated from the pump shaft of the first delivery pump 31. The second output shaft 332 is connected to the pump shaft of the second delivery pump 32 through a second clutch 334, so that the second output shaft 332 can be engaged with or separated from the pump shaft of the second delivery pump 32.

[0039] When the first output shaft 331 is engaged with the pump shaft of the first delivery pump 31 through the first clutch 333, and the second output shaft 332 is separated from the pump shaft of the second delivery pump 32 through the second clutch 334, the double-output motor drives the first delivery pump 31 to operate, and the driving liquid in the first container 10 can flow into the second container 20 through the first delivery pump 31, the communication pipe 34 and the second delivery pump 32. When the second output shaft 332 is engaged with the pump shaft of the second delivery pump 32 through the second clutch 334, and the first output shaft 331 is separated from the pump shaft of the first delivery pump 31 through the first clutch 333, the double-output motor drives the second delivery pump 32 to operate, and the driving liquid in the second container 20 can flow into the first container 10 through the second delivery pump 32, the communication pipe 34 and the first delivery pump 31.

[0040] In some preferred embodiments, the first clutch 333 and the second clutch 334 are both electromagnetic clutches. Also, the first clutch 333 and the second clutch 334 are both electrically connected to the controller 35, so that the controller 35 controls the engagement and disengagement of the first clutch 333 and the second clutch 334. The controller 35 is also electrically connected to the first liquid level meter 11 arranged on the first container 10 and the second liquid level meter 21 arranged on the second container 20, so that the controller 35 controls the first clutch 333 and the second clutch 334 according to the liquid level of the driving liquid in the first container 10 and the second container 20 monitored by the first liquid level meter 11 and the second liquid level meter 21.

[0041] Again, in combination Figure 1 As shown, in some embodiments, the input pipeline 40 includes a first input branch pipe 41 connecting the input end 200 and the first container 10, and a second input branch pipe 42 connecting the input end 200 and the second container 20. The first input branch pipe 41 and the second input branch pipe 42 are both connected to the upper part of the first container 10, and the first input branch pipe 41 and the second input branch pipe 42 are respectively provided with a first valve 411 and a second valve 421. The first valve 411 and the second valve 421 are both one-way valves, allowing the gas-liquid mixed fluid to flow from the input end 200 to the first container 10 and the second container 20, but not allowing the gas-liquid mixed fluid to flow from the first container 10 and the second container 20 to the input end 200.

[0042] In some embodiments, the output pipeline 50 includes a first output branch pipe 51 connecting the output end 300 and the first container 10, and a second output branch pipe 52 connecting the output end 300 and the second container 20. The first output branch pipe 51 and the second output branch pipe 52 are both connected to the upper part of the first container 10, and the first output branch pipe 51 and the second output branch pipe 52 are respectively provided with a third valve 511 and a fourth valve 521. The third valve 511 and the fourth valve 521 are also both one-way valves, allowing the gas-liquid mixed fluid to flow from the first container 10 and the second container 20 to the output end 300, but not allowing the gas-liquid mixed fluid to flow from the output end 300 to the first container 10 and the second container 20.

[0043] In other embodiments not shown, the third valve 511 or the fourth valve 521 can be arranged only on the total pipe after the first output branch pipe 51 and the second output branch pipe 52 are combined, which can also prevent the gas-liquid mixed fluid from flowing from the output end 300 to the first container 10 and the second container 20.

[0044] In combination Figure 1 As shown, the use process of the gas-liquid mixed delivery device 100 provided in the present application will be described in detail below.

[0045] After the driving liquid enters the first container 10 and the second container 20 through the injection pipe 101 and fills the first container 10 and the second container 20, the controller 35 controls the first clutch 333 to engage the first output shaft 331 of the double-output motor with the pump shaft of the first delivery pump 31. The double-output motor drives the first delivery pump 31 to operate, so that the driving liquid in the first container 10 enters the second container 20 through the communication pipe 34 and the second delivery pump 32 under the action of the first delivery pump 31. As the liquid level of the driving liquid in the first container 10 decreases, the pressure in the first container 10 decreases, so that the gas-liquid mixed fluid can flow into the first container 10 through the first valve 411 on the first input branch pipe 41 from the input end 200. In this process, the driving liquid in the second container 20 can be discharged through the injection pipe 101 on the second container 20 to maintain the pressure in the second container 20 unchanged.

[0046] Until the liquid level of the driving liquid in the first container 10 decreases to the position of the first liquid level gauge 11, the controller 35 controls the first clutch 333 to disengage the first output shaft 331 from the pump shaft of the first delivery pump 31 and controls the second clutch 334 to engage the second output shaft 332 with the pump shaft of the second delivery pump 32 after receiving the signal sent by the first liquid level gauge 11. The double-output motor drives the second delivery pump 32 to operate, so that the driving liquid in the second container 20 enters the first container 10 through the communication pipe 34 and the first delivery pump 31 under the action of the second delivery pump 32. As the liquid level of the driving liquid in the second container 20 decreases, the pressure in the second container 20 decreases, so that the gas-liquid mixed fluid can flow into the second container 20 through the second valve 421 on the second input branch pipe 42 from the input end 200. In this process, the gas-liquid mixed fluid in the first container 10 flows to the output end 300 through the third valve 511 on the first output branch pipe 51.

[0047] Until the liquid level of the driving liquid in the second container 20 decreases to the position of the second liquid level gauge 21, the controller 35 controls the second clutch 334 to disengage the second output shaft 332 from the pump shaft of the second delivery pump 32 and controls the first clutch 333 to engage the first output shaft 331 with the pump shaft of the first delivery pump 31 after receiving the signal sent by the second liquid level gauge 21. The double-output motor drives the first delivery pump 31 to operate again, and the driving liquid in the first container 10 enters the second container 20 through the communication pipe 34 and the second delivery pump 32, so that the gas-liquid mixed fluid in the second container 20 flows to the output end 300 through the fourth valve 521 on the second output branch pipe 52. In this process, the gas-liquid mixed fluid again flows into the first container 10 through the first valve 411 on the first input branch pipe 41 from the input end 200.

[0048] The above process is repeated, and the gas-liquid mixed conveying device 100 can continuously convey the gas-liquid mixed fluid from the input end 200 to the output end 300. During the conveying process, since the cross-sectional areas of the first container 10 and the second container 20 are necessarily greater than the cross-sectional area of the output pipeline 50, the gas-liquid mixed conveying device 100 actually performs pressure boosting conveying on the gas-liquid mixed fluid.
