| 摘 要： | 焉耆盆地是在海西运动期褶皱基底和元古代结晶基底之上发育起来的中、新生代中小型叠合复合含油气盆地，其形成经历了古生代基底形成阶段、中生代前陆盆地演化阶段、第三纪压陷盆地发育阶段和第四纪走滑隆升阶段等4个演化阶段。燕山运动期和喜马拉雅运动期断裂活动控制了坳陷、隆起的形态和规模。构造变形以逆冲推覆和走滑为特点，并伴生大量局部构造。构造演化对油气系统的形成、油气藏保存条件和油气富集程度具有重要影响。 |

| Abstract: | Yanqi basin,located in south Tianshan mountain belt,is a Meso-Cenozoic medium-small superimposed composite hydrocar-bon basin developed on Hercynian fold basement and Proterozoic crystalline basement.Tectonic evolution in it underwent four stages of Pa-leozoic basement formation,Mesozoic foreland basin development,Tertiary compressional and depressed basin development and Quaternary strike-slip and uplifting.It is Yanshanian and Himalayan faulting that control configuration and scale of its depression and uplift.The struc-tural deformation is characterized by thrust nappe and strike-slip associated with a large number of local structures.Study shows that struc-tural evolution has a significant effect on formation of petroleum system,hydrocarbon reservoir preservation condition and hydrocarbon en-richment regularity. |
