在应用储层层次分析法和动态分析方法研究储层连通性的基础上，运用了FZI、聚类分析和相关分析方法，利用取心井资料和测井解释物性资料对鄂尔多斯盆地古岩溶气藏储层进行了流动单元的划分，共划分出了3类流动单元，得出了每一类流动单元的判别函数，从而进行全区气井流动单元的划分。研究结果表明，每个连通体的内部各类流动单元分布也比较复杂，既存在纵向上的递变，也存在横向上的递变；平面上在每个连通体的中部厚度大，连通好，边部厚度小，连通差；储层流动单元比沉积微相更精细地刻化了影响储层流体流动的地下结构，储层流动单元的研究对于气田的大规模开发具有重要的实际意义。

The reservoir connectedness of the Fassil Karst gas field in Ordos basin is analyzed using the methods of hierarchy analysis and dynamic analysis. On this basis, using the core data and petrophysical log interpretation data, the flow unit division of the reservoirs in Fassil Karst gas field is carried out by the methods of cluster analysis and correlation analysis. Three types of flow unit are plotted and the discriminants of each type are derived; thus the division is enlarged to all gas wells in the area. The research results show that the main units with superior reservoir petrophsical properties are distributed in the middle of the interconnected formations; the properties of the interconnected formations grade horizontally or vertically. The flow unit division method is better of underground structure of the reservoir fluid flowing than the sedimentary microfacies method. The distribution of remaining oil can be forecast by studying the flow units. The study of reservoir flow unit plays a very important role in raising field efficiency as well as development.
