| Abstract: | Considering the effect of fracture on sandy rock reservoir, the equivalent permeability and deformation parameter of rock-body are got in the paper. Through the equivalent parameter, the equivalent continuum media model of seepage field and deformation field are established. The fluid-solid coupled model and its compute method are obtained,too. The coupled bridge is the relation between permeability and strain. It is significant to study the flow rule in the sand stone fracture oil reservoir. |

| Keywords: | equivalent model permeability tensor fluid-solid interaction fractured reservoir |
