| 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. |
