The majority of discovered reserves is central Sichuan Basin, but the economic development to the reserves is difficult because of the high saturation of water in gas reservoirs. Based on comprehensive study on the gas accumulation conditions, the evaluation to gas resource of Xujiahe formation is done, which points that exploration potential regions are Xu 2 and Xu 4 of Jinhua-Pengxi in central Sichuan Basin, and Xu 3 of Jiange in northwest of basin, where the source rock and reservoir as well as fracture are developed well. High-production gas from lots of wells and discovered scale reserves show that these potential regions will become the important new fields in Xujiahe formation, Sichuan Basin.
