Description

Technical Field

[0001] The utility model relates to the technical field of natural gas exploration, in particular to a gas extraction device for oil and natural gas exploration. Background Art

[0002] Natural gas refers to all gases that exist naturally in nature, including gases formed by various natural processes in the atmosphere, hydrosphere, and lithosphere (including oilfield gas, gas field gas, mud volcano gas, coalbed methane and biogenic gas, etc.). An experimental tank gas extraction device is required during natural gas exploration.

[0003] A gas extraction device for oil and gas exploration disclosed in the Chinese utility model patent application disclosure CN214952477U is a gas extraction device for oil and gas exploration. A connecting structure is provided on the gas extraction equipment, and a clamping plate is provided in a connecting groove on a rubber hose on the connecting structure. A clamping groove and a through groove are provided on the connecting pipe. When the gas extraction equipment is used, the gas extraction equipment is held by hand to perform an air suction operation, and the gas is placed into the connecting pipe through a guide groove on the gas extraction pipe. The tightness of the hand when holding the gas extraction equipment is likely to cause deformation of the gas extraction equipment. The clamping plate is located in the clamping groove, and the rubber hose makes the gas extraction pipe unaffected by the tightness, so that the gas extraction pipe remains unobstructed during the gas extraction process, and the flowability of the gas entering the gas storage pipe is increased. The silicon tube is used to increase the stability of the connection between the gas extraction pipe and the gas extraction equipment when tightness is generated, so as to avoid deformation of the gas extraction equipment during gas extraction. However, the stability of the connection between the gas extraction pipe and the gas extraction equipment is not high enough, and it cannot be quickly disassembled, which is inconvenient to use.

[0004] Secondly, silicon tubes are used to ensure a stable connection between the gas extraction pipe and the gas extraction equipment. If the silicon tubes are damaged at a later stage, the strength of the connection will be greatly reduced, and the probability of deformation of the gas extraction equipment during gas extraction will be increased, which urgently needs to be developed.
