摘　　要：通过引入熵原理来计算各个影响因素的权重进行油藏综合分类。结果表明,流度和每米采油指数对分类结果的影响最大。在此基础上,根据综合指数计算结果对江苏不同类型开发单元进行分类,各类单元对应的采收率也存在明显的差异。从不同开发单元单井产量变化特征分析结果来看,不同开发单元在不同时期投入的油井产量变化也存在着较明显的规律性,可为后期的开发调整、指标预测和年度配产提供参考。According to weights of each influencing factors calculated entropy weight algorithm, the reservoir classification was conducted. The results indicated that mobility and oil - production index per meter have a largest impact on the reservoir classification. On this basis, difference types of development units were divided by calculation results of comprehensive in- dex. And there are obvious differences in oil recovery rates of each type of units. From analysis of production changes in difference development units ,there are obvious rules of production changes at various stages. This can provide an important decision reference for development adjustment, index prediction, and annual production allocation at later stage.
