摘　　要：驱替特征曲线法是研究油田含水规律、预测开采指标和标定可采储量最常用的方法,目前已形成50多种。在这些曲线中,筛选出能够描述不同形态的含水率与采出程度关系的曲线一直是油田开发工作者永恒的研究课题。通过对钟德康驱替特征曲线和Gao-Ⅰ驱替特征曲线特性的对比分析表明:两类水驱曲线均具备描述不同形态的含水率与采出程度关系曲线的特性,但前者无驱替特征曲线相对应,而后者有驱替特征曲线相对应,其应用范围更大,是最理想的驱替特征曲线。Water displacement curve is the most common method for water cutrule study,productive index prediction and recoverable reserve calibraion,There are more than 50 methods of such a kind nowadays,However,selecting the curves that may describe the relationship between different water cut styles and recovery percent are the permanent topics to ioilfield development operators.This paper water displacement curves are of the characteristic of describing different water cut styles vs.recovery percent,the former has nno corresponding water displacement curve,but the latter has.So the latter is the most perfect water displacement curve with wider application than the former.
