Abstract: Analyses of twelve characteristic curves by water displacement using in China, Soviet Union and the United States of America. Conception of the methods relating to three types of equation of relative permeability curve includes the basic characteristics of various oil fields. The relationship equation between the cummulative oil production and composite water cut is obtained for every method, so that estimated recoverable reserves can be derived with production data. Seven oil fields with different oil viscosity were selected to compare adaptability of every method and analyze the causes. The forecast methods which are suitable for middle viscosity oil fields in our country have been recommended. Based on the work mentioned before the evaluation of method of characteristic curve by water displacement is given.

摘要： 本文分析了中国、苏联、美国12种水驱特征曲线的性质、方法的提出分别与三种类型的相对渗透率曲线表达式有关,这些方法基本概括了各种类型油田的特征.文中还用微分法求出各种方法对应的累积产油里与含水率的关系式,从而可用生产资料直接计算可采储圣.选择了我国七个原油粘度不同等级的油田,对比不同方法的适用性,并初步分析了原因,推荐了适合我国中等粘度油田的预测方法.综合以上分析提出了对水驱特征曲线法的评价.
