Abstract: Based on the black-oil model in multiphase fluid and the continuum mechanics theory, a theoretical modeling equation of immiscible saturated two phase seepage coupling with deformed porous media is presented. A simple discussion shows that the coupling effect between seepage and rock deformation may be obvious in some cases.
