中文摘要	川西平落坝构造是龙门山推覆构造山前的一个潜伏构造.该区中、上侏罗统为干旱～半干旱气候条件下的,三角洲～湖泊过渡相沉积,气源主要来自深层上三叠统须家河组,属于典型的"次生气藏".通过对该区气源、储集、圈闭、运聚、保存等成藏条件的详细研究,认为①该区中、上侏罗统天然气成藏条件优越,古构造优先捕集,为天然气早期富集成藏并继承性发展提供了有利条件;②相控下的优质砂体为天然气聚集提供储存空间;③断层为烃源气体跨层运移提供输导通道;④裂缝发育系统决定产层的高产等成为该区天然气捕集成藏的主控因素.
英文摘要	The Pingluoba structure of western Sichuan is a buried structure in front of the Longmen Mountain over thrust structure. In this area, the braid deltalake transitional facies on the arid and semi-arid climate condition are developed in the Middle and Upper Jurassic, the source of gas mainly comes from deep Xujiahe formation, and the gas reservoir belongs to the typical "the secondary gas pool" . By detailed study of the conditions about the source, the reservoir, the trap, characteristics of gas migration accumulation, gas preservation and so on, it is recognized that forming conditions of Middle and Upper Jurassic are good in this area. The study shows that the main controlling factors of the gas reservoir forming are preferential capturing of gas in the palaeo-structure which provides good conditions for early accumulation and succession development of gas, the quality sand body which is under control of sedimentary facies and provides pore space for gas accumulation, the fault offers the migration pathway for the cross formational flow of natural gas, and the fracture-developed system which decides the high production of producing pays.
