[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. The description of at least one exemplary embodiment below is actually only illustrative and in no way restricts the present invention and its application or use. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0039] As Figures 1 to 5 shown, an air drilling gas supply system is provided in an embodiment of the present invention. The air drilling gas supply system includes a gas supply module 100, a tail module 300, and a booster module 200. Among them, the inlet of the gas supply module 100 is used to communicate with an air compressor 400, and the outlet of the tail module 300 is used to communicate with a drilling device 500. The booster module 200 has a first shunt pipeline 210 and a second shunt pipeline 220 connected in parallel. The inlet ends of the first shunt pipeline 210 and the second shunt pipeline 220 are both connected to the outlet end of the gas supply module 100, and the outlet ends of the first shunt pipeline 210 and the second shunt pipeline 220 are both connected to the inlet side of the tail module 300. The inlet of a booster 600 is provided on the first shunt pipeline 210, and a first stop valve 211 is provided on the first shunt pipeline 210.

[0040] Applying the technical solution of the present invention, the air drilling gas supply system includes a gas supply module 100, a booster module 200, and a tail module 300 connected in sequence. The gas provided by the air compressor 400 can be supplied to the drilling device 500 through the gas supply module 100, the booster module 200, and the tail module 300 in sequence to realize the drilling operation. In the booster module 200 provided in this application, by switching the on / off state of the first stop valve 211, the booster 600 can be selectively connected to the gas supply system. When the first stop valve 211 is switched to the connected state, the first shunt pipeline 210 can connect the booster 600 to the gas supply system, and the gas is supplied to the drilling device 500 after being boosted by the booster 600; when the first stop valve 211 is switched to the disconnected state, the first shunt pipeline 210 is not connected to the overall gas supply system, and the gas can be supplied to the drilling device 500 only through the second shunt pipeline 220 to meet the usage requirements of the drilling device 500 in different situations. By providing the booster module 200 in the gas supply system, a fixed modular pipeline can be provided for the connection of various devices, which is convenient for the flexible layout of the overall gas supply system, without the need to temporarily connect pipelines and devices at the work site, improving production efficiency and ensuring production safety.

[0041] Referring to Figure 1 and Figure 2As shown, a plurality of gas supply interfaces 101 are provided on the gas supply module 100. The plurality of gas supply interfaces 101 are all used to communicate with the exhaust ports of the air compressors 400, so as to facilitate the use of multiple air compressors 400 for gas supply at the same time. When different numbers of air compressors 400 need to be used, only the operation of the air compressors 400 needs to be controlled, and there is no need to temporarily adjust the pipeline.

[0042] Referring to Figures 1 to 4 As shown, the tail module 300 has a first confluence pipeline 310 and a second confluence pipeline 320 connected in parallel with each other. The gas outlet ports of the first confluence pipeline 310 and the second confluence pipeline 320 are both connected to the drilling device 500. The first confluence pipeline 310 is used to communicate with the gas outlet port of the booster 600. The gas inlet port of the second confluence pipeline 320 is connected to the gas outlet port of the second shunt pipeline 220. A second cut-off valve 321 is provided on the second confluence pipeline 320. Through the above settings, the tail module 300 can connect the booster 600 in parallel to the gas supply system through the first confluence pipeline 310 and the second confluence pipeline 320 in cooperation with the first shunt pipeline 210 and the second shunt pipeline 220. The first shunt pipeline 210 and the first confluence pipeline 310 form a first flow path, and the second shunt pipeline 220 and the second confluence pipeline 320 can cooperate to form a second flow path. In this way, the gas supplied to the drilling device 500 through the second flow path is the output gas of the air compressor 400, and the gas supplied to the drilling device 500 through the first flow path is the gas boosted by the booster 600. Whether the second flow path is connected to the gas supply system can be controlled by controlling the opening and closing of the second cut-off valve 321. When the second cut-off valve 321 is switched to the off state, only the first flow path supplies gas to the drilling device 500 to meet the gas pressure requirement of the drilling device 500; when the second cut-off valve 321 is switched to the on state, both the first flow path and the second flow path supply gas to the drilling device 500, which can meet the gas flow requirement of the drilling device 500 while meeting the pressure requirement of the drilling device 500.

[0043] Referring to Figure 2 and Figure 3 As shown, the booster module 200 has a plurality of high-pressure inlets 213, and the plurality of high-pressure inlets 213 are all used to communicate with the gas inlet ports of the boosters 600. The tail module 300 has a plurality of high-pressure outlets 312, and the plurality of high-pressure outlets 312 are all used to communicate with the gas outlet ports of the boosters 600. In this way, the connection of the boosters 600 is realized, and the number of the boosters can be adjusted flexibly.

[0044] Referring to Figure 1 and Figure 3As shown, an air supplement interface 212 is provided on the side wall of the first shunt pipeline 210, and the air supplement interface 212 is used to communicate with the air compressor 400. Through the above settings, multiple air supplement interfaces 212 communicate with the air compressor 400, which can supplement gas for the first shunt pipeline 210. When the gas flow rate is insufficient, the air compressor 400 connected to the air supplement interface 212 can be turned on to meet the usage requirements of the drilling device 500.

[0045] Specifically, in an embodiment of the present application, the air supplement interface 212 is arranged upstream of the booster 600, so that the supplemented gas can be introduced into the booster 600.

[0046] In the present application, a third stop valve 311 is provided on the first confluence pipeline 310. Through the above settings, the third stop valve 311 can cut off or connect the first confluence pipeline 310. When the first stop valve 211 is disconnected, the third stop valve 311 can be disconnected to prevent the fluid from flowing through the first confluence pipeline 310 to the booster 600, ensuring the correct fluid flow direction and preventing damage to the booster 600 caused by fluid backflow.

[0047] Furthermore, the boosting module 200 further includes a boosting main pipeline 230. The air inlet of the first shunt pipeline 210 and the air inlet of the second shunt pipeline 220 are both connected to the air outlet of the boosting main pipeline 230, and a fourth stop valve 231 is provided on the boosting main pipeline 230. Through the above settings, the fourth stop valve 231 provided on the boosting main pipeline 230 can control the overall on-off of the boosting module 200, realizing the overall control of whether the gas supply module 100 and the boosting module 200 are connected, which is convenient for the overall control of the gas supply system.

[0048] Specifically, in the present application, the gas supply system has the following working states:

[0049] 1. The first stop valve 211 and the third stop valve 311 are disconnected, the second stop valve 321 and the fourth stop valve 231 are opened, and the gas passing through the gas supply module 100 is directly supplied to the drilling device 500 without boosting;

[0050] 2. The first stop valve 211, the third stop valve 311 and the fourth stop valve 231 are opened, the second stop valve 321 is disconnected, and the gas passing through the gas supply module 100 is all supplied to the drilling device 500 after being boosted by the booster 600;

[0051] 3. The first stop valve 211, the third stop valve 311, the second stop valve 321 and the fourth stop valve 231 are all opened, and the gas passing through the gas supply module 100 is divided into two parts, one part is directly supplied to the drilling device 500 without boosting, and the other part is supplied to the drilling device 500 after being boosted by the booster 600.

[0052] Specifically in the present application, the tail module 300 further includes a tail main pipe 330. The tail main pipe 330 is used to connect to the drilling device 500. The gas outlet of the first converging pipeline 310 and the gas outlet of the second converging pipeline 320 are both connected to the gas inlet of the tail main pipe 330. A one-way valve 331 is provided on the pressurization main pipe 230. Through the above settings, the one-way valve 331 can control the gas flow direction in the overall gas supply system, prevent gas diversion, and ensure the stable operation of the overall gas supply system.

[0053] Specifically, a material filling port 332 is provided on the pressurization main pipe 230, and the material filling port 332 is located downstream of the one-way valve 331. Through the above settings, materials such as clear water, foaming agent or lubricant can be added to the gas to be supplied to the drilling device 500 through the material filling port 332, ensuring the safety and reliability of the drilling construction.

[0054] Further, the tail module 300 has an exhaust pipe 340. The exhaust pipe 340 is connected to the tail main pipe 330. A tail gas treatment component 700 is also provided on the gas drilling gas supply system. The exhaust pipe 340 is used to connect to the tail gas treatment component 700. Through the above settings, the tail gas treatment component 700 can treat the residual gas in the gas supply system after the drilling device 500 stops working, preventing the tail gas from being directly discharged and affecting the production environment.

[0055] Optionally, the tail gas treatment component 700 can be a noise reduction device to reduce the noise of the discharged tail gas; it can also be a gas storage device to store the discharged gas. In onshore gas drilling, the gas used as a medium can be air or inert gas. By setting the gas storage device to recover the gas, the gas consumption in the overall production process can be reduced.

[0056] Specifically in the present application, the tail gas treatment component 700 includes a silencing tank 710 and a flow control valve 720. The flow control valve 720 is provided on the pipeline connecting the exhaust pipe 340 and the silencing tank 710. Through the above settings, the gas discharged from the exhaust pipe 340 can be introduced into the silencing tank 710 to absorb the impact force generated by the exhaust gas and reduce the noise of the exhaust gas; and by setting the flow control valve 720 for control, the speed of the gas flowing into the silencing tank 710 can be controlled on the premise of controlling whether the silencing tank 710 is connected to the overall gas supply system, further improving the noise reduction treatment effect of the silencing tank 710.

[0057] It should be noted that the silencing tank 710 can be a resistance silencing tank that absorbs sound waves, such as by filling sound-absorbing materials like fiberglass or rock wool, to reduce noise, or it can be a reactive silencing tank that reduces noise by changing the propagation path of sound waves, such as bending and reflection, as long as the noise reduction effect can be achieved.

[0058] Specifically in the present application, a monitoring component 110 is provided on the gas supply module 100 to monitor the state of the gas entering the gas supply system. By providing the monitoring component 110, various parameters of the gas entering the gas supply system can be monitored, facilitating the staff to monitor and adjust according to the actual production situation.

[0059] Specifically, the monitoring component 110 can be a pressure gauge to monitor the real-time pressure of the gas introduced into the gas supply system.

[0060] Specifically, the monitoring component 110 can be a thermometer to detect the temperature of the gas.

[0061] Specifically, the monitoring component 110 can be a flow meter to detect the flow rate of the gas introduced into the gas supply system.

[0062] Furthermore, a variety of monitoring devices such as a pressure gauge, a thermometer, and a flow meter can be set simultaneously to achieve real-time monitoring of various parameters of the gas.

[0063] Specifically in the present application, the first stop valve 211, the second stop valve 321, the third stop valve 311, and the fourth stop valve 231 can be set as direct-flow stop valves to adapt to the control of high-speed gas in gas drilling operations.
