Abstract By combining elastio-plastic theory and porous flow mechanics，the fluid-solid coupling mathematical model adapted to low permeable oil reservoir is established. The threshold pressure gradient and the fluid-solid coupling feature of low permeable reservoir are considered in the model. The calculation program of oil seepage is designed on the basis of black oil model. The calculation program deformation is designed according to the elasto-plastic FEM program. Using the software，a low permeable reservoir is simulated. Contrasting to the result calculated by oil black model，the fluid-solid coupling effect is obvious.
