摘要: 针对目前在国内用得比较多的4种水驱特征曲线所存在的问题,提出了一种既简单又综合了甲乙两种类型关系的f wR*水驱特征曲线。将丙型与丁型结合提出新的水驱特征曲线,并和经典的水驱特征曲线完全等效的一种水驱特征曲线表达式,同时又能反映含水率-采出程度关系的多条曲线,对它的形状和性质作了一些研究,指出今后水驱特征曲线的研究方向是找出更简单、准确、实用的广义水驱特征曲线。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: Aiming at the existing problems in 4 types of water drive characteristic curves which are widely used at home, a simple f wR* water drive characteristic curve which integrates the relation of type A and type B is presented.Type C and type D are integrated to propose new water drive characteristic curves,which are the water drive characteristic curve expression equivalent completely equivalent to classic water drive characteristic curve,and able to reflect the relation of water cut-recovery degree,the shape and the feature are analyzed.It is pointed out that research direction for water drive characteristic curve in the future is to find out more simple,accurate and practical generalized water drive characteristic curve.Practical calculation indicates the established new types of water drive characteristic curve matches practical data well,and more reliable.

Key words: oilfield development, water drive characteristic curve, recoverable reserves, recovery degree
