Abstract: In view of permeability prediction in well logging reservoir evaluation，based on the idea of facies-controlled modeling，the flow unit analysis is carried out to group the unit，in the study area，four apparently characterized flow units are identified.The fuzzy cluster analysis is conducted by using AC，DEN，CNL，GR and flow zone index which can best characterized accumulation property of reservoir，modeling is implemented by selecting the optimal samples with maximum membership degree being greater than 70%，identifying model of flow unit is obtained.The permeability model of complex glutinite reservoir is set up，prediction accuracy of reservoir fluid permeability is improved.The recognition provides reference for understanding heterogeneous reservoir physical property.

Key words: heterogeneous reservoir, glutinite, flow unit, permeability prediction, fuzzy cluster analysis
