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。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 waterflood performance and predict recovery factor. The chart is simple and easily understood, which performed well in Shuanghe oilfield.
