摘　　要：钻井是开发深部地热资源最直接的技术手段,但深部地层处于高温高压环境,其应力分布复杂。本文针对深井井壁围岩变形区分布开展了研究,对各变形区域的岩石力学进行了分析,在力学理论上为深部井壁稳定研究提供了指导。Drilling is the most direct technical means to develop deep geothermal resources.However,the deep strata are in high temperature and high pressure environment,the stress distribution is very complex.In this paper,the regional distribution of surrounding rock deformation in deep wellbore is studied,the rock mechanics of each deformation area is analyzed.This can provides a guidance for the study of deep wellbore stability in mechanical theory.
