摘要： 针对累积产水量与累积产油量的半对数关系和西帕切夫公式在使用中存在的问题,基于油层物理学中有关油田综合含水率的计算公式fw=1/(1+μwKr0/μ0Krw),经理论推导提出了一种新的水驱特征曲线描述方程Np=A2+(A0+A1A2)/(Lp-A1),经实例验证是可行的。

Abstract: Aimed at solving the problems of semi-logrithm relationship of cumulating water output and oil output, as well as the problems for applying the Sypachev's equation, this paper based on formula fw=1/(1+μw Kr0/μ0Krw), which is usied to calculate oilfield's composite water cut, through theory derivation, recommended a new equation, Np=A2+[(A0+A1A2)/(Lp-A1)], for waterflooding characteristics curve description. Application instances have demonstrated and verified that it is applicable.

Key words: water injection, oilfield, water displacement curve, Application
