摘要： 基于水驱曲线关系的研究成果，得到了含水率与累积产油量或采出程度的半对数直线关系。该直线关系可以利用高含水阶段的资料，对油田的采收率进行有效的预测。

Abstract: A semilog straight-line relationship of water cut vs. cumulative oil production or current recovery of OOIP has been given acoording to the researched results available from water drive's curves. Using the data from high-water-cut stage in this straight-line relationship, a valid prediction of recovery factors in oilfields can be obtained.

Key words: Oilfield, High-water-cut stage, water cut, Cumulative production, Current recovery of OOIP, Recovery factor
