摘要： 为了便于对比, 更好地反映不同的含水上升规律, 对目前已有的6 种含水率与采出程度关系进行总结。将它们变换为含水率与可采储量采出程度关系, 并研究了曲线的图形特点。这类关系可以反映不同的含水上升规律, 但由于采用了瞬时含水率参数, 影响了参数求取的准确程度, 而采用产油量、产水量、产液量、注水量的累积值, 就消除了这一缺陷。

关键词: 水驱, 含水率, 采出程度, 可采储量, 曲线

Abstract: The established 6 relationships of water cut and recovery percent of reserves have been summarized.These relationships were transformed into those between water cut and recovery percent of recoverable reserves, and these curves investigated.Such relationship can reflect different water cut trends, while the use of instant water cut affected the computing accuracy which can be removed by using the culmulative values of oil production, water production, liquid production and water injection rate.

Key words: Water drive, Water cut, Recovery percent, Recoverable reserve, Curve
