The Pearl River Mouth Basin is one of the important petroliferous basins in China. At first, the main intervals of oil and gas exploration and development in the basin were concentrated in Neogene, but with the advancement of rolling development, Paleogene has gradually become the focus and hotspot of oil and gas development. Lufeng A Oilfield is the earliest oilfield to develop Paleogene in the Pearl River Mouth Basin, and the development layer system is Enping Formation of Paleogene. Due to the strong heterogeneity of sand body in the study area, with the deepening of development process, the oilfield has exposed many problems, such as unclear interpretation of oil-water interface, unclear corresponding relationship of sand body and so on. In order to solve these problems and meet the needs of oil and gas development, it is urgent to clarify the sand body configuration. In this paper, using the idea of analytic hierarchy process and the research method of seismic sedimentology, through the comprehensive analysis of core, three-dimensional seismic, logging and production performance data, the sand body configuration in Enping Formation of Lufeng A Oilfield is finely characterized. The results show that: (1) Shallow braided river delta front deposits are developed in Enping Formation of Lufeng A Oilfield, mainly including underwater distributary channel, mouth bar and inter-distributary. (2) The underwater distributary channel in the front of braided river delta in the study area is mainly multi-level braided network-like channel, and on the profile shows lateral shear superposition, lateral splicing and isolated superposition styles, (3) Small scale underwater distributary channel and lobed mouth bar are developed at the end of the delta front, and lateral splicing, isolated and bar-channel composite sand body superposition styles are developed in the section, (4) The braided river delta in the study area is formed by the splicing and superposition of sand bodies of different types. Along the provenance direction, the combination style of single channel sand bodies is transformed from multi-stage cutting-stacking style to lateral cutting-stacking and lateral splicing style, finally to isolation style. At the same time, the development scale of single channel is gradually reduced, the development number of single channel is gradually increased, and the connectivity between sand bodies is gradually reduced.
