一种简单实用的水驱特征曲线

A new practical water displacement curve.

提出了一种非常简单而实用的水驱特征曲线，并导出了相应的递减曲线。这种水驱特征曲线可以反映多种类型的ｆｗＲ关系曲线，因此适用于不同油水粘度比的水驱油田。图１参２（陈志宏摘）

Based on the characteristics of two kinds of water displacement curve in common use, a very simple and very practical water displacement curve was presented and the corresponding decline curve was derived.This water drive curve can reveal many types of curve of f w R * relations. Thus, it can be used in water drive reservoirs with any oil water viscosity ratios.
