| Abstract: | Based on the theory of fluid mechanics in porous media and rock mechanics, a fully-coupled multiphase flow-mechanics model of reservoir was established, and numerical simulation by FEM(Finite Element Method) and FDM(Finite Difference Method) was also given; the simulation results show evolution laws in seepage field and stress field ,including variation of rock mass mechanics parameters. By the influence of coupling, stress was adjusted between the various layers with corresponding deformation characteristics. Finally, a practical example of casing damage in petroleum engineering is presented, from which it is demonstrated that coupling is an important issue to be considered. |
