On the basis of core observation and logging data, this paper studies the sedimentary facies and their characteristics of stream channel reservoir in the tenth sand group of Member 2-10 of Paleogene Shahejie Formation (Es₂¹⁰) in Block 4 of the Xianhe oilfield of the Dongying Depression. Braid fluvial delta and lacustrine facies have developed in Es₂¹⁰ in study area, and the distribution of the sedimentary facies controls the development of the reservoir bed. The property data of cores show that the reservoir of Es₂¹⁰ sand group is characterized by modified mid-porosity and low-permeability. The property of the reservoir is correlated with permeability and the heterogeneity of that is strong. The artificial neural network method is used to predict the reservoir thickness, distribution and porosity of Es₂^10-1 and Es₂^10-2.The results provide evidences for petroleum exploration and development.
