Abstract: The effective stress in the rock matrix of a reservoir increases as a result of the decline in pore fluid pressure with the continuous withdrawal of subsurface fluids.Under such conditions,more load is transferred to the rock matrix,and thus the rock is compacted or deformed,which can sometimes produce ground subsidence.The soil consolidation can be simulated by using a finite element numerical model of fluid-solid coupling of fluid seepage in a deformable porous medium.In addition,the production process of oil wells is also simulated.
