摘要
Abstract
A hi-performance air-tight premium connection is designed and developed for service I in the shale gas well with complex conditions.Based on the analysis of the possible load upon the casing in the shale gas well,a specific working condition simulation test is designed.The main items of the test include the verification of the connection s over-torque resistance,the internal pressure cycle test to simulate the fracturing process,the resonance bending fatigue test and the sealing test.The test results show that the foresaid premium connection possesses both high compression resistance and high over-torque resistance,and can still guarantee excellent sealing ability even after the action of the fatigue load.All the properties of the connection meet the requirements related to the premium connection performance for deep shale gas development.关键词
