Finite Element Analysis of the Influence of Special Threaded Joint Parameters on Casing Connection Performance
摘要
Abstract
In order to improve the connection and sealing performance of special threaded casing joint,a finite element analysis model was established for the special threaded casing joint by using the ANSYS system in this paper,and the influence of different structure parameters including the angle of thread bearing surface,shoulder surface,and taper of the thread on the casing joint performance was studied based on the factor rotation idea.The research results showed that a smaller angle value should be chosen in the design of the bearing angle considering the influence of the plastic deformation and slippage failure.Under the combined external load conditions,the effect of auxiliary seal on the shoulder angle was better than that of the right angle shoulder.Under the action of the upper buckle and the axial tension load,when the internal thread taper of the coupling was equal to the taper of the external thread of the casing,the connection performance of the casing joint was better.关键词
