摘　　要：残雪构造和断桥构造是主要受中新世末龙井运动挤压作用影响形成的大型背斜构造 ,渐新统花港组是主要勘探目的层。本文分析了构造内的断裂分布及成因、岩浆活动、局部构造特征 ,并从构造的落实程度、圈闭面积大小。Canxue and Duanqiao Structures are large sized anticline that is mainly formed by compression of Longjing Movement in late Miocene. Exploration target intervals mainly distribute in Huagang FM of Oligocene. Faulting distribution and mechanism,magmatic activity and local structure characteristics are analysed in this paper. Petroliferous evaluation is made from structure reliability, trap area, local structure type and source-reservoir-cap assemblage.
