摘　　要：文中论述了低渗透性多孔介质中非线性渗流理论的几个问题,阐明了渗流流体的性质,指出了多孔介质对流体通过的选择性,提出了新的非线性渗流方程,用实验资料对其进行了验证,分析了该方程演变功能,表明它可以描述各种渗流规律.该方程的各项参数都可从实验中直接得到,应用方便,并且参数的物理意义明确.This paper discusses some problems of nonlinear porous flows in low permeability porous media, the properties of the porous flow fluid, and the selectivity of fluids in passing through porous media. Based on these characters, a new porous flow model, which can better describe low permeability reservoirs, is established. This model can describe various patterns of porous flows, as Darcy＇s linear law. All parameters involved in the model, with definite physical meanings, can be obtained directly from experiments
