摘要：俞启泰阐述了50多种水驱特征曲线，但每种水驱特征曲线对应的含水率与可采储量采出程度关系曲线只为单一的凸型、S型或者凹型曲线。针对4种水驱特征曲线，根据它们在表达式上的相似性进行了组合，利用累计产水量和累计产油量替换了水驱特征曲线中的累计产液量，由此得到了2种新型水驱特征曲线。通过这2种新型水驱特征曲线的对比，发现第一种水驱待征曲线代表的含水规律曲线与实际的数据更加相近。新型水驱特征曲线既可以预测油田的可采储量，也可以预测凸型、S型和凹型这3种含水上升规律，与原水驱特征曲线相比实用性更加广泛。

Abstract: Yu Qitai described 50 types of the water-drive characteristic curves, but each of their corresponding f. R curves only refers to the single convex type, S type or concave curve ones. In the light of the four types of the wa-ter drive characteristic curves, according to the similarity in the expressions, they were combined and assemblaged, the cumulative water production and cumulative oil production replaced the cumulative liquid production in the wa-ter drive characteristic curves, and then two new types of the water flooding characteristic curves were obtained. Through the comparison of these two new types of the water flooding characteristic curves, it is found that the first kind of the water drive characteristic curve is more similar to the actual data. The new water drive characteristic curves can not only predict the recoverable reserves of the oilfield, but also can predict the watercut rising rules of
3 kinds of the curves stated above, so these new curves possess much more wider applicability. Key words: water-flooding characteristic curve; watercut law; recoverable reserve
