| 摘 要： | 累积存水率是评价注水开发油田注水状况及注水效果的一个重要指标。从累积存水率的定义出发，以丙型水驱特征曲线为例，基于水驱特征曲线推导出累积存水率与含水率数学关系式，并结合相对渗透率曲线求解丙型水驱特征曲线经验系数进行了探讨。同时，推导了乙型、丙型和丁型3种水驱特征曲线的累积存水率与含水率的数学关系式。该推导所得到的理论公式对水驱油田进行效果评价及挖潜和调整等方面应用具有一定的参考价值。

| Abstract: | The cumulative water-injected rate is one of important indices for evaluating the water injection status and effect of a waterflood oil field. The mathematic expressions between cumulative water-injected rate and water cut are deduced and discussed based on the definition of cumulative water-injected rate and water drive characteristic curves, including the expressions for B-type, C-type and D-type curves, taking C-type curve as an example. The theoretical expressions could be as a guide for response evaluation, stimulation and modification of a waterflood oilfield. |
