摘　　要：鄂尔多斯盆地富昌油田延长组长6储层为典型的碎屑岩储层。通过介绍碎屑岩储层流动单元的概念、研究意义以及研究方法,利用概率统计法及聚类分析的方法,依据流动层带指标FZI对研究区长6段储层进行了流动单元划分,并且通过对铸体薄片、物性资料、扫描电镜、压汞试验等基础资料的分析,对各流动单元的岩石物理特征进行分析。研究区延长组长6段储层被划分为5类流动单元,各类流动单元具有独立的孔隙度与渗透率关系,表明不同流动单元具有不同的微观孔隙结构及岩石物理特征。The reservoir of chang 6,Yanchang Formation in Fuchang area is the typical clastic rock reservoir in Ordos Basin.In this article,the concept and the research approach of clastic reservoir flowing unit were introduced.the flowing units of reservoir of chang 6 were divided by using probabilistic method and cluster analysis method,according to flowing index FZI.The petrophysial characteristics of flowing units were studied on the base of experimental data of thin section analysis,image analysis,SEM,mercury penetration,etc..The results show that the reservior of Chang 6,Yanchang Formation can be divided into 5 kinds of flowing unit.Every kind of flowing unit has certain formulation of porosity and permeability,which indicates that different flowing unit has different microscopic pore structure and physical features of rocks.
