Abstract: Shallow water delta has become a key object in the field of oil and gas geology. Further deepening its sedimentary model and sand body distribution law is of great significance to accelerate the oil and gas exploration and development of this kind of reservoir. In this paper, the sedimentary characteristics of shallow water delta in the near provenance system are studied and the regional characteristic sedimentary model is established by taking the upper Es3s5 member in Bamianhe Oilfield as an example and integrating the geological data such as core, logging and analysis. The results show that: under the influence of structural background, ancient material source, paleoclimate and other factors, the lithology of the upper Es3s5 of Bamianhe Oilfield is mainly fine sandstone, and the sand body size gradually increases from bottom to top, showing progradation characteristics as a whole. The sedimentary microfacies such as underwater distributary channel, underwater natural levee sheet sand and so on are mainly developed. The estuary bar is basically not developed, and the underwater distributary channel is distributed in an intertwined and contiguous manner, and a large area of sheet sand is formed in the shallow water area.
