摘要: 本文全面研究了水驱特征曲线,指出了流行的理论解释的不尽正确,分析了油层润湿性、渗透率的非均质性、油水粘度比,井网和人工措施对水驱特征曲线的形态,近似直线段的起止区间的影响,尤其着重研究了油层非均质的作用。

Abstract: The cut vs. recovery curves are thoroughly znvestigated in this paper.The misleading prevalent theoretical explanation has been pointed out, and the influence of formation wettability, heterogeneity in gcrmzeahility, viscosity ratio, well patters and artificial condition on the shape of cut vs. recovery curve as well as the appearence of its straight lins interval are analyzed.Particular attentions arepaid to the influence of heterogeneity of oil bearing formation.
