摘要
利用大型有限元分析软件ADINA,建立套管在温度荷载、重力以及地层的蠕动荷载组合下的三维的数值模型。通过分析在热力耦合作用下套管的轴向应力、轴向应变、环向应力、环向应变和最大位移情况,认为在热力耦合作用对套管的影响是非常大的。
Using the FEA software Adina to set up the three—dimensional numerical model,which consider the load including temperature、gravity and creep formation.Through analysis the axial stress,axial strain,circumferential stress,circumferential strain and largest displacement caused by the thermal—mechanical coupling to obtain conclusions, in order to raise the utilization rate of casing and decreasing rate of destruction.
