摘要
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.
