The relation between the deformation shape of casing and the areas and subjected to ground stress and the theory solution of non-uniform in-situ stress were analyzed.
对套管的变形形态与地应力作用大小、应力范围之间的关系和非均匀地应力的求解进行了研究。
When the horizontal in-situ stress is non-uniform, the casing stress is non-uniform at all times not only in the isotropic formation but also the orthotropic ones.
在非均匀水平地应力条件下，无论地层为各向同性或各向异性，套管应力均呈现非均匀分布态势，其套管应力极值变化不大。
