摘要: 在分析已有水驱特征曲线研究成果的基础上,构建出了4类水驱特征曲线。这些水驱特征曲线具有3个主要方面的特点:第一是适应性比较广,即不受粘度大小的选择,也不受油藏类型的限制,完全可以描述不同形态含水与采出程度曲线和含水上升规律;第二是解决了已有广义(理想)型水驱特征曲线存在的缺陷——无法描述具有无水期特征的含水与采出程度关系;第三是求解方法相对简单。油田应用实例表明,该方法效果很好,值得其他油田借鉴和推广。

关键词: 水驱, 可采储量, 采出程度, 含水率, 方法

Abstract: Based on the study of existing water drive characteristic curves, 4 types of water drive characteristic curves are screened out, which accord with three main characteristics. The first can be used to describe different forms of water cut curves and recovery percent with wide adaptability and without viscosity and reservoir type limitation; the second is to resolve the fault of existing general (ideal) water-drive characteristic curves which can not describe the correlation between water cut and recovery percent in the period of water free production; the third is relative simple for solution. The case study shows that it is of good effect and worthy of reference and popularization for other oilfields.

Key words: water drive, recoverable reserve, recovery percent, water cut, method
