Abstract Baojing area of Hunan Province is a new shale gas exploration block, and the geological characteristics and accumulation rule of shale gas are still worthy to be studied. The geological characteristics of Longmaxi Formation shale gas in the study area were summarized in sedimentology, porosity and permeability of the reservoir, geochemistry, gas content and other reservoir characters. According to the study of hydrocarbon generation history, fracture characteristics, detachment layer movement, and fault effect, shale gas accumulation mode was explored. The results show that Longmaxi Formation shale gas in Baojing area of Hunan Province has high organic matter abundance, moderate thermal maturity, high brittle mineral content, and good physical properties, which means this reservoir has shale gas enrichment conditions. The shale experienced the stage of gas generation from Permian to Middle Jurassic. At the end of Middle Jurassic, trough-like folds in a fold-and-thrust belt were formed and the multiple reticular cracks and bedding decollement layer in vertical dimension were formed in Longmaxi Formation reservoir. Therefore, the accumulation model of shale gas in Longmaxi Formation in Baojing area of Hunan Province can be briefly summarized as follows: migration in detachment layer, fracture accumulation, residual in pores, plugging by the fault, enrichment in higher areas and accumulation in box shape.

Key words： Baojing area of Hunan Province shale gas accumulation model hydrocarbon evolution reserving space detachment layer fracture Longmaxi Formation
