摘要: 从油田开发耗水率的基本概念出发, 定义耗水指数为当注采比为1 时的耗水率。结合童宪章给出的水驱曲线公式,推导了耗水指数与采出程度的关系式;据此可以制作耗水指数的理论图版。耗水指数的理论图版可用来评价注水开发效果,并可预测水驱采收率。该图版简单实用,容易掌握,应用于河南双河油田,取得了成功。

Abstract: Based on the basic concept of water-consumption-factor in oilfield development, water-consumption-index was defined as water-consumption-factor with injection-production-ratio of 1.Combined with water displacement curve given by Tong Xianzhang, the relationship between water-consumption-index and recovery percent was derived by which the theoretical chart of water-consumption-index was developed.It can be used to evaluate water flood performance and predict recovery factor.The chart is simple and easily understood, which performed well in Shuanghe oilfield.
