根据累积存水率的定义,建立了累积存水率与含水率关系的数学模型,进而建立了累积存水率与采出程度关系,并利用辽河油田不同断块不同开发阶段的实际开发数据进行了回归对比,给出了可实际应用的累积存水率与采出程度关系和开发效果评价E 方法。

Based on the definition of remaining rate of cumulative injected water , a mathematical model about the relationship between cumulative injected water remaining rate and water cut has been set up. Therefore a relationship beween cumulative injected water remaining rate and extraction degree has been established. Regression correction has been made by using the actual development data of different faults and different development stages of Liaohe Oilfield ,and a practical relationship between cumulative injected water remaining reate and extraction degree has been presented ,and on the same time , a E - development evaluation method also have been presented.
