Coupling analysis of multiphase flow and stress for oil reservoir

The mathematical models of coupling analysis on reservoir multiphase flow and stress are established based on the theories of rock mechanics and mechanics of multiphase flow through porous media.The models characterize of multiphase fluid flow in reservior and coupling effect of seepage and strees.The coupling laws between seepage and stress are studied. The method and steps for implementing the coupling analysis are given.The effectiveness and utilities for coupling analysis are verified by an example.
