摘    要:在四川盆地西部巨厚的上三叠统和侏罗系碎屑岩沉积中,有数量可观的天然气资源贮存在常规和非常规圈闭内,构成颇具特色的致密砂岩含气领域。浅层天然气藏的形成与深部高压气源、古隆起、有利储盖层组合及断裂疏导系统有关;浅层气藏的勘探模式宜采取深浅结合、由浅入深及滚动延伸的多学科联合实践活动。勘探表明,侏罗系确实存在着连片展布和纵向叠置的气藏群体。由于此领域处于工农业发达的成都平原,加速浅层致密砂岩天然气的勘探开发,具有良好的经济效益和社会效益。

关 键 词:四川盆地  西  侏罗纪  致密砂岩  浅层气  成因  勘探  模式

Abstract:With a lot of natural gas resources,the conventional and non conventional traps of the heavey detrital rock sedimentation of the Upper Traissic and Jurassic in the west part of Sichuan Basin form a charateristic tight sand gas bearing area.The formation of shallow gas reservoirs is relative to deep high pressure gas source,palaeohigh,good reservoir cap assemblage and fault conducting system.The exploration of shallow gas reservoirs is a multi discipline practice action,from shallows to deeps,of deep shallow conbination and rolling extention.The explorated result shows large areal and vertical multi traps of gas reservoirs are reliably in the Jurrassic.
Keywords:Sichuan Basin  West  Jurrassic  Tight sand rock  Shallow gas  Genesis  Exploration  Mode.
