摘　　要：用ANSYS软件对油井套管进行力学分析,建立符合工程实际的力学模型,并进行非线性接触分析.该方法比传统的单纯对套管进行分析求解更符合工程实际,结论更加合理,从而确定了套管—井壁系统更为切合实际的应力分布及破坏形式,给油井工程设计提供参考.By using ANSYS software, this paper makes the mechanical analysis on the structure of oil well casing, builds the mechanical model in accordance with the actual projects and conducts nonlinear contact analysis solution for it, which is more practical than simply for the casing and whose conclusion is more reasonable. As a result, a more practical stress distribution and damaging style of the casing-well system can thus be identified and some useful references to the well design can be provided.
