中文摘要：
阐述了油水相对渗透率曲线与岩石的孔隙结构、岩石的润湿性之间的关系。以S油田低渗透砂岩储层为例,以油田36块岩心的相对渗透率曲线数据为基础,将相渗曲线形态分为水相下凹型和水相上凸型两种类型。并对两种类型相对渗透率曲线形态特征进行分析,得出水相下凹型相对渗透率曲线更有利于注水开发。
英文摘要：
The relationship between the oil-water relative permeability curve and pore structure of rock,the relationship between the oil-water relative permeability curve and the wettability of rock are expounded.With the S oilfield low permeability sandstone reservoir as an example,based on data about 36 core of the relative permeability curve,relative permeability curve shape is divided into the aqueous phase under the concare type and aqueous phase on the convex type.Analysis of two kinds of curve shape feature,the aqueous phase under concave relative permeability curve is more advantageous to the water injection development.
