Abstract：The Upper Permian marine-continental transitional shale developed extensively in Lower Yangtze area, with great thickness and rich organic matter content, but the exploration degree of this area is low and it lacks systematic analysis on shale oil and gas geological conditions. The burial depth of the shale in Dalong and Longtan Formations in southern Jiangsu-Anhui area is favorable, and the exploration wells deployed previously have obtained good oil and gas display. Based on previous data, the authors comprehensively analyzed the accumulation and preservation conditions of shale oil and gas in the Upper Permian shale in southern Jiangsu-Anhui Province by means of field investigation, core observation, test analysis and data comparison. The results show that the Upper Permian strata in this area have good hydrocarbon generation and reservoir conditions, and the differences in thermal evolution maturity are related to tectonic evolution, reflecting the differences in oil and gas preservation and enrichment conditions. Based on previous studies, we suggested that fine research on shale oil and gas preservation conditions and burial evolution history should be carried out in key areas to seek exploration breakthrough and to improve the exploration and development of shale oil and gas in the entire Lower Yangtze region.
