油水相对渗透率曲线是评价油水两相渗流的特征曲线，是油藏工程研究的重要内容。通过大量的岩心驱替实验，在建立油水相对渗透率计算模型的基础上，运用函数的凸凹性将相渗曲线划分为水相凹型、水相凸型、水相直线型3类。评价了相渗曲线类型与储层物性、共渗点、共渗范围、驱替效率、含水率及沉积相之间的关系。分析表明注水开发对相渗曲线变化影响较大，注水可改善水相凹型曲线岩心储层物性、有利于原油开采，而注水对水相凸型曲线岩心储层会产生不利影响。

Oil -water relative permeability curve is characteristic curve of evaluating oil water two -phase flow and al-so one of important curves in reservoir engineering.First,using a lot of core flooding experiments,on the basis of oil -water relative permeability model,relative permeability curves are divided into three types:aqueous concave,aqueous convex and aqueous linear by function concave -convex feature.Second,it is evaluated that the relationship between all kinds of rela-tive permeability curves and reservoir physical property,infiltration point,infiltration area,oil displacement efficiency,water cut,and sedimentary facies.At last,analysis results show that water flooding has large effect on relative permeability curve, and can improve core physical property of aqueous concave type curve which is beneficial to oil recovery.However,water injection has bad effect on core physical property of aqueous convex type.
