摘要
通过不均匀的毛细管组模型，建立了幂律型流体和宾厄姆（Ｂｉｎｇｈａｍ）流体渗流的广义达西定律和一般的渗流方程。
The nonuniform capillary the group model is used to establish the generalized Darcy′s law and a general equation of the power law fluid and Bingham fluid flow through porous media. The relationships are derived between the effective permeability and the effective viscosity of power law fluid versus the feature parameters of the fluids and formation media and between the starting pressure gradient of Bingham fluid and fluid feature parameters versus the feature parameters of the fluids and formation media.
