中文摘要：

四川盆地构造变形样式复杂,并且经历了多期构造演化,陆相碎屑岩层系油气成藏条件复杂。通过对四川盆地基本构造样式分析、碎屑岩层系油气圈闭类型及典型油气成藏模式综合分析后认为,四川盆地整体上可以划分为3个构造变形区,由西至东可以划分为川西—川西北前陆盆地区、川中隆起区、川东—川东南隔挡式褶皱变形区,不同构造变形区具有不同的油气成藏模式,分别为＂近源下生上储裂缝型成藏模式＂、＂远源不整合输导型岩性成藏模式＂、＂近源断裂疏导型背斜成藏模式＂,并认为基底古隆起、分带差异构造变形、分层差异构造变形是该种成藏模式的主要成因,对后期的油气勘探具有一定的指导意义。

英文摘要：

Sichuan Basin is of multi-phase tectonic evolution,complicated structure styles,and complex hydrocarbon accumulation conditions.Through analyzing the basic tectonic styles,trap styles of clastic and accumulation patterns of Sichuan Basin,three main deformation zones can be found in Sichuan Basin：W–NW Sichuan foreland basin,uplift in Central Sichuan Basin,and ejective fold in E–SE Sichuan.Hydrocarbon accumulation patterns in three deformation zones are different from each other.Finally,the main reasons of three deformation zones are discussed in the paper,such as basement uplift,zonation differential deformation,stratification differential deformation.The research is of the guiding significance for future hydrocarbon exploration in Sichuan Basin.
