Casing coupling is one kind of oilfield drilling tools, which is mainly used for the connection of tubing. Tubing coupler mainly solves the problem of fatigue fracture of existing coupler due to stress concentration. The structure of the oil pipe coupling is as follows: the end of the oil pipe is connected to the inner wall of the coupling with conical threads, and the end of the coupling and the oil pipe are connected with the same threads and the same pitch flat threads. It has the characteristics of relieving the stress concentration at the root of the outer thread of the oil pipe connected with a single conical thread, and is not easy to produce fatigue fracture, with good connection effect. It can effectively prevent the occurrence of oil well tubing column breakage.
