��Starting from the special geological conditions that gas and water are together in the little-median fracture systems in Yangxi Series of Permian in Southern Sichuan, through survey, analysis and inference of the practice data and some peculiar phenomena, the basical geological model of the pool in which the gas coexists with the water and the new way for finding gas by water withdrawal are proposed in this paper, i.e. by use of the original energy of gas for draining off the water from the wells located in the water-block to make the water down and gas out, and then to discover new gas reserves. 相似文献
