Based on the investigation of the complex sedimentary system of Es3 in Jiangjiadian area of Linnan depression, the petrological characteristics, sedimentary facies types and characteristics of the upper, middle and lower sub sections of Es3 area are studied in depth and detail by combining the geological data of core, thin section and logging. The results show that Es3 in Jiangjiadian area is influenced by Xiakou fault. The lithic feldspar sandstone is relatively developed with low composition maturity. The gap filling is mainly clay minerals, kaolinite and Yimeng mixed layer are the main components. The sedimentary structure type is mainly bedding structure, and a few of them are developed in the stratification layer and biogenetic structure. The sedimentary facies is mainly delta facies and lake facies.
