FLOW UNIT CLASSIFICATION OF PU53 RESERVOIR
濮53块流动单元分类方法研究

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. The study of relation between flow units and microfacies indicates the distributary channel sandbody forms mainly good and excellent flow unit which often be easy to be affected by injected water, while sheet-like sandbody in front of distributary channel and inter-channel sandbody form fair and poor flow unit which often act as barrier and baffle in the injected water flooding.
