油套管抗挤毁性能的有限元分析

FEM Analysis on the Collapse Property of Casing

    摘要
  • 摘要: 运用有限单元分析方法详细考察了承受均匀外压力的样本油套管在不同椭圆度、不同壁厚不均(或称偏心度)、以及不同椭圆度和壁厚不均组合等初始几何缺陷的情况下的应力变化及其分布,并作出相应的初始几何缺陷与应力变化的曲线.

     

    Abstract: Finite Element Method (FEW is applied to research and analyse the distribution of stresses in a sample casing under uniform external pressure, which has various initial geometric imperfections (ovality and eccentricity).
