摘　　要：油藏含油饱和度下限是评价储层流体性质和含油性的重要指标,是储量计算、开发方案编制的重要参数之一。该研究运用压汞曲线的"J"函数、相渗曲线、饱和度正逆累计方法对西峡沟的原始含油饱和度进行研究确定。Lower limit of oil saturation is an important index for evaluating reservoir fluid property and oil-bearing characteristics,and it is one of the important parameters in calculating reserves and designing development program. Initial oil saturation of Xixiagou reservoir is determined and studied by using＂J＂function of mercury penetration curve, relative permeability curve and positive and negative accumulation method of oil saturation.

关 键 词：压汞“J”函数 相渗曲线 正逆累计 含油饱和度下限
