摘要： 水驱特征曲线法是用来预测水驱油田的产量及可采储量的重要方法。国内外学者先后提出了很多种水驱特征曲线的表达式。由于油田开发的复杂性,使得统一的定量描述难度很大,因此各类曲线都难以描述油田开发的全过程,而只适用于某一特定的含水阶段。目前在国内用得比较多的水驱特征曲线主要有甲、乙、丙、丁4种,在4种最常用的水驱特征曲线的基础上,提出了既简单又实用的甲乙型和丙丁型综合水驱特征曲线。通过实例计算表明,所建立的新型水驱特征曲线与实际数据拟合相关性更强、结果更可靠。

Abstract: Waterdrive characteristic curve is an important method for forecasting production rate and commercial reserves of waterflood field. There are many types of waterdrive characteristic curves presented by scholars at home and abroad. As the complexity of oilfield development, it is difficult to describe them quantitatively. Each type-curve is only suitable for particular water cut stage rather than the whole process of oilfield development. The curves widely applied in China are four types of A, B, C and D, based on which AB and CD type-curves are proposed in this paper. The case study demonstrates that these type-curves are good accordance with real data and possess simplicity, practicability and reliability.

Key words: oilfield development, waterdrive characteristic curve, type curve, recoverable oil, reserve, recovery percent
