摘要：目前常用的水驱特征曲线通常只对应一种含水率与可采储量采出程度，在实际应用中存在一定的局限性。国此选取两种在表达式上类似的水驱特征由线，通过适当变形得到可以代表凸型、凹型和S型的含水上升规律的一种新型水驱特征曲线，并推导出含水率与可采储量采出程度的关系式。通过3不不同油田实例对比分析，发现新型水驱特征曲线特别适用于高含水期和特高含水期的油田，对中低含水期的油田适用性较差。

Abstract: The commonly used water flooding characteristic curve in reservoir dynamic analysis usually only corresponds to a kind of water cut and recoverable reserves recovery degree, which is restricted in practical application. Two kinds of water flooding characteristic curves with similar expressions are selected, and a new water flooding characteristic curve which can represent the water rising law of convex, concave and S type is obtained by proper deformation. The relationship between water cut and recoverable reserves is deduced. Through the comparative analysis of 3 different oilfield examples, it is found that the new water drive characteristic curve is especially suitable for oil fields with high water cut period and extra high water cut stage.
