Abstract: According to the characters of thick reservoir in Pu-53 Block,the flow units of this reservoir were subdivided into 19 short-term cycles based on the base-level cycle analysis.Based on the distribution of reservoir property factors and the result of clustering analysis,the reservoir was divided into four types including E,G,F and P types by using the reservoir factors including permeability,porosity,percolation factor and reservoir factor.A model for predicting flow units of the reservoir was established with the stochastic modeling technique and other techniques.The space distribution of flow units was randomly predicted with the threshold value.The small layers of the reservoir were classified into four types with different oil and gas reserves.The type II and type III layers have the extraordinary important place in the development of the reservoir.The remaining oil distribution indicates that the internal and areal heterogeneities play the most important role in the generation of remaining oil.
