Abstract: Based on fractal theory and methods and the mercury injection data of shale samples from the Longmaxi formation of the Lower Silurian in Shuanghe area in Southern Sichuan, the quantitative research of the pore structure features is made, giving the fractal dimension D1 and D2. According to the fractal curves, the pore structure of shale of the Longmaxi formation is divided into three types: seepage pore, coagulating?absorption pore and absorption pore. It provides support for researches of nanoscale pore structure of shale and occurrence and migration mechanism of shale gas in this area
