利用应力-应变理论、达西定律和热传导理论,从岩体变形、流体压力以及温度改变三个方面研究入手,研究注水地层的应力变化.利用温度场、渗流场和应力场三者之间耦合关系,建立了注水地层相应的控制方程.通过有限元分析软件对注水地层进行有限元仿真模拟,并为后续套管损坏研究提供了可靠的理论依据.%The stress variation in the water injection formation from the solid deformation , the fluid pressure and the temperature by using stress-strain theory, darcy law and heat transfer theory is investigated. It established the corresponding control equations by using the relationship of THM. For the finite element simulation and the bushing damage research , it provides necessary reference information.
