摘要(Abstract)：
本文从毛管数概念出发，利用毛管压力曲线，给出了毛管数与残余油饱和度间相关关系的估算方法，对于不同地区不同渗透率的9块岩样的算例看出，岩石性质不同，毛管数与残余油饱和度间的数量关系是不同的。计算结果与试验结果基本吻合，它可以方便地为化学驱油数值模拟计算提供毛管数与残余油饱和度间的相关关系。
ABSTRACT
From the concept of capillary number, the author presents the estimating method on the relationship between capillary number and residual oil saturation. The application examples for 9 samples with different permeabilities taken from various areas indicated that different rock properties have different quantitative relationship between capillary number and residual oil saturation. The results calculated are in agreement with the test results, therefore it can provide a relationship between capillary aumber and residual oil saturation for the numerical simulation for chemical flooding.
