摘　　要：基于流固耦合力学理论，建立了弹塑性变形油藏中多相渗流的数学模型，该模型考虑了渗流与变形的耦合作用，以及注采交变载荷作用下油藏多孔介质的弹塑性变形特征；The mathematical model of multiphase flow in an elastoplastic deforming oil reservoir is developed based on the theory of fluid solid interaction mechanics, with the coupling effect of flow and deformation and the elastoplastic deforming characteristics of reservoir porous medium under the alternative loads considered in the model. The approach of coupled numerical simulation and an example are presented.
