Abstract: Based on the comprehensive analysis of drilling，logging，seismic and core data，the reservoir accumulation characteristics of the second member of Sinian Dengying Formation in Penglai-Zhongjiang area were systematically studied. The results show that：（1）During the sedimentary period of Sinian Dengying Formation in Sichuan Basin，with the intrusion of seawater，the ancient land was mostly submerged or eroded and flat‐tened，and the basin gradually evolved into a carbonate platform. During the sedimentary period of the upper submember of the second member of Sinian Dengying Formation（upper Sinian Deng-2 member），platform margin shoal facies and platform margin mound facies were developed in Penglai-Zhongjiang area，and they can be further divided into six subfacies：shoal core，shoal edge，intershoal sea，mound core，mound edge，and intermound sea，which are favorable facies zones for reservoir development.（2）The reservoirs in the upper submember of the second member of Dengying Formation in the study area are mainly composed of algal dolomite and algal sand clastic dolomite，with four types of reservoirs developed：residual intergranular pore and intergranular dissolved pore type，intragranular dissolved pore and algal framework pore type，fracture type and pore type. The thickness distribution characteristics of the reservoirs are consistent with the sedimentary facies distribution characteristics，and the reservoirs located in the mound/shoal core of platform margin have a larger cumulative thickness.（3）The natural gas in the upper submember of the second member of Dengying Formaiton in the study area is mainly derived from the source rocks of Qiongzhusi Formation. The source rocks have a large thickness，high organic carbon content and high degree of thermal evolution. The gas reservoir has good hydrocarbon sources and sealing conditions，with two types of good assemblages：“upper source，lower reservoir and upper cap”and “side source，side reservoir，and upper cap”.（4）The oil and gas filling in the study area mainly occurred during Triassic-Cretaceous，which is multi-stage quasi-continuous. The gas reservoirs of the upper submember of the second member of Dengying Formation mainly mainly went through four stages：the accumulation stage of paleoreservoirs from Ordovician to Silurian，the paleo-reservoirs failure stage from Silurian to Carboniferous，the hydrocarbon regeneration and reaccumulation stage from Permian to Triassic，and the crude oil cracking and gas generation stage from Triassic to Jurassic.

Key words: platform margin facies, algal dolomite, algal sand-clastic dolomite, side source and side reservoir, upper source and lower reservoir, crude oil cracking and gas generation, source rocks of Qiongzhusi Formation, the second member of Dengying Formation, Sinian, Penglai-Zhongjiang area, Sichuan Basin
