摘要
Reservoir formations typically display high degrees of spatial variations over multiple length scales. Moreover, several physical phenomena affect the flow pattern in different hierarchies. However, a full description of flow and deformation that includes all these scales exceeds the current computational capabilities. To overcome this deficiency, each physical effect should be treated separately on its area of influence. In the present article, the fluid transport and deformation of porous media are determined through separate frameworks in different scales. The finite element method is combined with multiscale finite volume (MSFV) to solve the solid equilibrium and fluid flow equations. Interactions between soil and fluid multiscale frameworks are instated through tight iterative coupling. Then the Multiscale Multiphysic Mixed Geomechanical Model (M(3)GM) is presented. The M-3 GM not only maintains advanced features of MSFV in flow patterns but also improves with properties of finite elements in the soil domain. Finally, indicative test cases are analyzed and reasonable results are achieved.
