【摘要】 本文从川南二叠系阳新统中多为气水共存的中小型裂缝系统这一特殊地质条件出发,通过对实际资料和若干奇特现象的调查及分析推断,提出气水共存气藏的基本地质模式及找气新途径——排水找气。即利用气体的天然能量,从位于水体中的水井中排气,实现水落气出,发现新的天然气储量。更多还原

【Abstract】 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.更多还原
