摘　　要：注水开发油田累计产水量和累计产油量存在一定的相关性,在半对数坐标上呈近似直线关系。通过水驱特征曲线的分析,推导出预测油田可采储量、采收率和综合含水率的公式,并利用回归方法计算直线斜率、截距,可用于指导油田开发和下步挖潜。There is a correlation between accumulated water production rate and accumulated oil production rate, which is a linear relation on semilog coordinate. Through analysis of water flooding characteristic curve t equations are derived for predicting reserves, oil recovery, integral water cut in the oilfields, regression method is used to calculate straight slope, intercept, which would be used to guide oilfield development and tapping the potential in the future.
