摘　　要：The 4th Member of Shahejie Formation in Yanjia Area is located in the north wing of the central uplift zone of Dongying Depression, facing Chenjiazhuang Uplift in the north and Minfeng subsag in the south. Large-scale glutenite bodies developed during the 4th Member of Shahejie Formation, forming a distribution pattern of "canal and segment correspondence" with relatively low degree of exploration. Based on the study of Yanjia deep paleogeomorphology, sand body distribution characteristics and seismic facies characteristics, combined with the drilling situation, the source system and sedimentary evolution of glutenite are studied to determine the source direction and sedimentary evolution characteristics of deep glutenite in Yanjia area. Based on the detailed description of the glutenite reservoir by various geophysical methods, the main controlling factors for the formation of deep oil and gas reservoirs in this area are determined by means of oil source correlation, source rock analysis, oil and gas thermal evolution law, reservoir anatomy, matching relationship between oil and gas phase state and lower limit of oil and gas-bearing physical properties, etc.
