摘    要:本文给出了考虑介质变形的双重孔隙介质流固耦合渗流模型,并考虑渗流参数随有效应力而变化的非线性双重孔隙介质流固耦合渗流,在此基础上,本文还推导了双重孔隙介质非线性系数非线性等流固耦合流流计算,并给出了算例。

关 键 词:双重孔隙介质  流固耦合  渗流  多孔介质  非线性  裂缝性油藏

Abstract:based on the double porosity concept and taken into account the media deformation, this paper has presented to derive a set of non linear govern equations which describe the fluid behavior flowing through the naturally fissured media with deformable matrix. When the coefficients varies with the effective stress of media, the equations are non linear. In addition, A computer program (based on finite element method) has been developed. The program is capable of modelling problems associated with single and double porosity, having two options of constant and variable coefficients. In the variable coefficient option, at each time step(effective stress step), the values of coefficients are updated using the set of constitute relationship. A example is presented here also.
Keywords:double porous media  coupled permeability  porosity media non  linear  fissured reservoir
