Abstract

The invention discloses a pipeline joint for oil field gas production. The pipeline joint for the oil field gas production is characterized in that the pipeline joint comprises a gas production pipe and a flange; one end of the gas production pipe is in sleeve connection with the flange; one end of the flange is communicated with a second sleeve through bolt threads; multiple telescopic rods are in interspersed arrangement on the inner walls of both sides of the second sleeve; springs are sleeved on the outer portions of the multiple telescopic rods; gas pipe fixed jackets are disposed on bothends of the multiple telescopic rods; one ends of the multiple springs are respectively fixedly connected with the outer walls of both sides of the gas pipe fixed jackets; sealing strips are mountedinside the two gas pipe fixed jackets. The pipeline joint for the oil field gas production has the advantages of facilitating an operator to fix the gas production pipe with the arrangement of regulating valves, bolts, the telescopic rods and the gas pipe fixed jackets, solving the problem of air leakage caused by poor sealing between a gas pipe and another gas pipe, enhancing the oxidation resistance of sleeves with anti-rust paint applied to the surface of the first sleeve and the second sleeve, and extending service life.

Description

technical field [0001] The application belongs to the technical field of oilfield gas recovery, and in particular relates to a pipeline connector for oilfield gas recovery and a use method thereof. Background technique [0002] Natural gas is a non-renewable resource on the earth. All kinds of mechanical products are inseparable from natural gas, ranging from aircraft tanks to small automobiles and ships. Natural gas extraction cannot be separated from the transportation of gas pipelines, the connection between gas pipelines and gas pipelines. Joints are required to seal the space, while the traditional gas pipe joints are simple in structure, and the joints are not tightly sealed. Long-term exposure to the natural environment may cause leakage, which in turn leads to waste of natural gas. [0003] Therefore, in order to further improve the efficiency of transporting gas, it is necessary to provide a pipeline joint for gas recovery in an oil field and a use method thereof. ...
