摘要

采用具有两个时间常数的简单数学模型，研究了双孔隙度饱和介质渗透率测量过程中的压力变化动态。我们认为这些达西定律无法解释的瞬态动力学方面是宏观和微观孔隙中流动的宏观图像。

Dynamique des écoulements en milieux poreux double échelle

Simple mathematical models with two time constants are used to study the dynamics of pressure variation during permeability measurements on dual porosity saturated media. We think that these transient phase dynamic aspects, which Darcy's Law cannot explain, are a macroscopic image of flows in macro and micropores.
