摘要
膨胀套管螺纹接头联接的性能关系到膨胀套管应用过程中的可靠性。以J55钢级膨胀套管为研究对象,采用有限元法,分析了J55钢级膨胀套管采用一种负角特殊螺纹结构的接头,在几种加载情况下的力学性能和套管膨胀后机械性能发生的显著变化。
The expansion casing threads joint performance is related to the application of the reliability in the process of expansion casing. With J55 grade steel expansion casing as the research object, using the finite element method, analysis of J55 grade steel expansion casing using a negative angle Premium Connections, under several loading conditions on the mechanical properties and mechanical properties of casing expansion after the obvious changes.
