Numerical Ezperimental Research of Seepage Characteristic for Filled Fracture Network

摘要：

In order to investigate the seepage characteristic for fracture network filled with porousmedium．using hydrodynamic theory,based on the N-S equation,the numerical experiments of fracturedporous media filled with porous medium were done. The relationship of filled fracture networkpermeability,porosity and particles diameters was deduced by the numerical experiments. The resultsshown that when φ>0．6,the analytical expression agrees well with experimenml data,then modifiedthe expression when φ≤0.6,finally represented a new expression. It helps us to research the seepagecharacteristic of filled fracture network．
