摘　　要：以致密砂岩气藏成藏机理为指导,综合利用烃源岩有机地化和储层孔渗参数等资料,对台西盆地致密砂岩气藏发育条件进行了探索性研究。在概括烃源岩、储集层及封盖保存等基本地质条件对油气聚集控制的基础上,通过分析致密砂岩气藏的形成机理,认为台西盆地具备良好的致密砂岩气藏发育条件,存在巨大的天然气勘探潜力,盆地东部陆区白垩系—中新统下部、西部海域南日坳陷白垩系—始新统、澎湖坳陷始新统下部为致密砂岩气藏发育有利层位,是台西盆地天然气勘探的新领域。Following the gas accumulation mechanism in tight sandstone reservoirs, hydrocarbon source rocks and reservoirs parameters （such as porosity and permeability） were applied to research the development conditions of tight sandstone gas reservoirs in the Taihsi Basin. The study of accumulation mechanism suggests that gas accumulation in tight sandstone is related to the occurrence of source rocks, reservoirs, sealing and preservation conditions. The Taihsi Basin has good conditions for forming tight sandstone gas reservoirs and vast potential areas for natural gas accumulation. The Cretaceous-lower Miocene in the eastern land area, the Cretaceous-Eocene in the Nanri Depression （the western waters）, and the lower Eocene in the Penghu Depression （the western waters） are favorable strata for tight sandstone gas reservoirs in the Basin.
