摘要(Abstract):
Muskat依据相对渗透率是饱和度的单变量函数的概念将Darcy定律推广到油水两相渗流中。分析两相渗流过程发现:饱和度梯度是决定渗流过程的重要参数,在指出Muskat公式缺陷的同时提出了改进两相渗流公式的新观点。
Based on the concept that the relative permeability is the single variable function of the saturation,Muskat extends Darcy Law to the oil and water phase flow. The analysis of the flow process shows that the saturation gradient is the important parameter determining the seepage behaviors,the disadvantage of Muskat Formula is pointed out,in the meantime,the new idea to improve the two-phase flow equation is presented.
