摘要
地壳中许多含油气储层是由层状结构的沉积岩层所组成。根据岩层的沉积的特点 ,将其假设为横观各向同性体。推导了横观各向同性岩层的地应力与岩层的各向异性、地层倾斜角之间的关系式。进行了横观各向同性地层井眼稳定性分析。
There are many oil-bearing rocks are composed of sedimentary rocks with layer structure in the earth's crust. On the basis of sedimentary texture of the rocks, the formations are considered as transversely isotropic material. The relations between the crust stresses and the elastic parameters in titled formation are given. The analysis of stabilization of wellbore in transversely isotropic material is presented. The conclusions are of some guiding significance to well design and drilling operation.
