In this method, Stoneley wave attenuation from AC log is divided into two parts: attenuation through porous media and percolation attenuation through pore-fluid.

该方法把由声波测井数据得到的斯通·利波衰减分为介质内衰减和孔隙流体渗流衰减两部分。

An extension of Finite Cell Method (FCM) is presented, which was used to simulate mass transport process in porous media with unhomogeneous porosity. We also gave two numerical examples here.

对有限颗粒法(F CM)进行了推广，将FCM用于模拟二维变孔隙率下多孔介质中污染物运移情况，并给出相应的数值算例。

Miscible compressible displacement in a porous media is modelled by a nonlinear coupled system of two parabolic equations: the pressure equation and the concentration equation.

有界区域上多孔介质中可压缩可混溶驱动问题由两个非线性抛物型方程耦合而成：压力方程和饱和度方程均是抛物型方程。
