中文摘要：
野外地质考察和地震剖面解释表明川西龙门山冲断带具有复杂的构造地质特征，认为研究区发育类型众多的构造变形样式，主要有背冲断块、三角带构造、逆冲断层带和断块构造、断层相关褶皱构造以及双重构造等，不同类型的构造变形样式形成不同类型的构造油气藏。不同类型构造油气藏具有一定的分布规律，在平面上具有分带性，并与龙门山冲断带的主干断裂密切相关，如北川－映秀断裂与马角坝－通济场－双石断裂之间主要发育与断层相关的褶皱型油气藏；马角坝－通济场－双石断裂与广元－关口－大邑断裂之间主要发育三角带构造型油气藏以及一些断滑褶皱型油气藏，等等。在纵向上具有分层性，区域性滑脱层之上发育各种类型的构造油气藏，主要有背冲断块型油气藏、逆冲断裂带内的构造油气藏等，滑脱层之下发育双重构造型油气藏、断层相关及与背斜有关的构造油气藏。
英文摘要：
Field investigation and explained seismic profiles show that Longmen Mountains thrust belt has very complex structural characters, such as pop-up, triangle belt, fault related fold and duplex. These structures can form various kinds of hydrocarbon pools and have some regular patterns in their distributions： one is zonation, this means that the distribution of pools made of various kinds of structures are close related to the main faults on Longmen Mountains thrust belt, for example, there should be some faults related to fold type pools between the Beichuan-Yingxiu fault and the Majiaoba-Tongjichang-Shuangshi fault and some triangle belt type pools between the Majiaoba-Tongjichang-Shuangshi fault and the Guangyuan-Guankou-Dayi fault, etc. ; the other is stratification, which means the detachment layers developed in Longmen Mountains thrust belt have very great influence on the pools＇ distribution in profiles, for example, the region on the detachment layers has more types of structural pools than that beneath the detachment layers.
