热采井套管螺纹连接有限元分析

Finite Element Analysis of Thermal Well's Casing Threads Joint

针对注蒸汽热采井套管螺纹连接的性能进行了ANSYS计算分析,建立了套管螺纹连接的有限元计算模型,选择了接触分析模块,计算了热采井套管连接螺纹牙的受力分布,得出套管螺纹连接在热采井中的力学性能变化规律。

This paper focuses on computational analysis of casing threads joint performance in the steam injecting well. By using ANSYS analysis software, the computational model of casing threaded joint, and then contact analytical module was chosen to calculate the force distribution of thermal well casing thread linking debit teeth. Thus the mechanical changing rule of casing threads joint＇s behavior in the thermal well was obtained from the result.
