摘　　要：以鄂尔多斯盆地中东部某区块致密砂岩储层为例,探讨多期河道叠加的致密砂岩储层流动单元研究方法。通过优选参数,选定孔隙度、渗透率、储层品质系数、流动层带指数作为参数因子,用聚类分析和判别分析方法进行致密砂岩储层流动单元分类和评价,认为用聚类分析法划分致密砂岩储层流动单元是合理可行的,对同类储层开发具有一定指导意义。The authors proposed on approach of multiple channel superimposed tight sandstone reservoir flow unit by using the data from a block in the middle-east part of Erdos Basin. The parameters such as porosity, permeability, reservoir quality coefficient and flow zone index were selected to classify the flow units. With the cluster analysis and discriminant analysis method, tight sandstone reservoir flow units were classified and evaluated. The study shows that proposed method is reasonable and feasible, and has certain guiding significance for development of similar reservoirs.
