采用基于Kozeny-Cayman方程的定量方法引用FZI、Φz、RQI、单位储层厚度、渗透率、孔隙度作为聚类分析的六个因素,利用Matlab软件,采用K-均值聚类分析法,对丹凤场须家河组流动单元进行划分,将流动单元分为一类、二类、三类流动单元。得到了流动单元的分类特征和分布规律。进一步得出丹凤场区块须家河组须四段气藏不同流动单元所体现出明显不同的储层特征。 Using the quantitative method based on the Kozeny-Cayman equation, the FZI, Φz, RQI, unit reservoir thickness, permeability and porosity were used as the six factors of clustering analysis. By using K- means clustering analysis method, Divide flow units of Xujiahe Formation in Fengqian, and divide the flow units into one type, two types and three types of flow units. The classification and distribution of flow units are obtained. The results show that there are obviously different reservoir characteristics in different flow units in Xujiahe Formation of Danjiachang Xujiahe Formation.
