摘要: 对现有的处理油水相对渗透率的方法提出了一种改进方法。新方法的基础是归一化和平均相对渗透率曲线。利用束缚水饱和度、残余油饱和度、残余油饱和度下的水相相对渗透率与空气渗透率的关系和归一化平均相对渗透率曲线,可以得出不同空气渗透率下的油水相对渗透率曲线,其中油相相对渗透率曲线形状不变,而水相相对渗透率曲线的形状随空气渗透率的变化而变化。

Abstract: The present method for treating oil-water per meability curves is improved. The base of this method is to ncrmalized and to average relative permeability curves. By using relationship between the irreducible water saturation、 the residural oil saturation. the wwater relative permeability at residtlal oil saturation and the air permeability as w'ell as. the normalized average relative permeablity'. one (an obtain oil-water relative permeability at different ait permeability in which the shape of oil-phase relative permcability curves keeps constant and the shape of water-phase relative permeability curves varies with the air permeability.
