Abstract: This paper introduces an identification of sedimentary microfactes by the pattern recognition approach using neural network. The approach firstly established the relationship between the logging facies and geological facies according to the key-well study as an identified pattern,then obtained intelligent knowledge by learning from the identified pattern, and finally applied the knowledge to identify the microfacies in unknown wells and sites again. The approach was successfully applied in the recognition and subdivision of sedimentary microfacies of the 4th member of the Shahejie formation, Wenlin Area, Zhongyuan Oilfield.
