就濮53块的实际地质情况,讨论了流动单元的分类方法。认为依据FZI进行流动单元分类存在诸多问题,不适于本区的特点,而采用聚类分析结合储层参数次总体分布特征进行的流动单元分类,考虑了储层内部的联系,是一种较好的分类方法。依据该方法,将濮53块的储层划分为4种类型,并研究了流动单元与成因砂体之间的关系,其中分流河道砂体形成的主要是极好型和好型流动单元,而席状砂与分流间砂体则形成了具有一定的封隔作用或渗流缓冲作用的低渗带或低渗缓冲带的一般型和差流动单元。

According to the characteristics of Pu53 reservoir, the methods for flow unit classification is discussed. The method based on flow zonation indicator and standardized porosity is not suitable to the study area for its inherent shortage. The method using clustering and sub-collectivity distribution of reservoir factors is a good one for the study because the inherent correlation of reservoir characters is considered in this method. Based on the method, 4 types of flow units are determined in Pu53 reservoir.
