摘　　要：大邑构造位于川西拗陷中段到南段的过渡带,既是龙门山推覆构造带与成都拗陷的盆山接合部,沉积上又是须家河组相区与香溪群相区的相变带。已有勘探成果研究表明,大邑构造油气成藏的烃源与储集等基础地质条件优越,但多期构造影响显著,形成了三个具不同特征的成藏类型,是一个受多期裂缝控制,经历了多期构造运动改造,地质条件复杂的气藏。The Dayi structure lies between middle section and south section of the west Slclauan aepresslon and in the junction of the Chengdu depression with the Longmenshan nappe structure and in facies change zone between the Xujiahe Formation and the Xiangxi Group. Existing exploration data indicate that the tectonic fracture in Dayi is characterized by good entrapment conditions with complicated geological conditions and influence of multiple structures.
