| 摘 要： | 套管破坏的原因主要是由于断层、蠕变地层、地震等所引起的非均匀荷载。通过建立三维的数值模型,考虑几种荷载的组合形式,采用有限单元法分析套管在不同的荷载组合下的力学和变形的性质。通过对此模型的分析以及ADINA后处理的数据表明：在轻微地震力作用下,对套管影响比较大的是断层和蠕动。

| Abstract: | The main reason of casing the destruction is the fault creep formation,caused by earthquakes and other non-uniform load.Through the establishment of three-dimensional numerical model,consider several forms of the load,use finite element to analyze casing in different combinations under the load of mechanics and the nature of deformation.In this model,the analysis showed that fault and wiggle have relatively large impact on the casing. |
