摘要： 焉耆盆地是在海西运动期褶皱基底上形成的中新生代含煤沉积盆地。从盆地形成演化、烃源岩条件、储集层、盖层及储盖组合、圈闭类型等基本石油地质特征出发, 对烃源岩的生烃史、储集层特征和演化进行了研究, 认为焉耆盆地主要有2 期油气生成和成藏事件。侏罗系含油气系统分布在博湖坳陷, 平面上可划分为北部凹陷含油气系统和南部凹陷含油气系统, 纵向上可划分为侏罗系原生型含油气系统和古近-新近系再生型含油气系统。

Abstract: Yanqi basin is a Mesozoic-Cenozoic coal-bearing basin formed on the Hercynian folded basement. Based on the basinal evolution, hydrocarbon source rock condition, reservoirs, cap rocks, reservoir-cap rock assemblage and trap types, this paper suggests that there are two major petroleum generation and accumulation events in this basin. The Jurassic petroleum system occurs in Bohu depression which can be divided into the northern sag petroleum system and the southern sag petroleum system in plane and into Jurassic primary petroleum system and Tertiary secondary petroleum system in longitudinal direction.

Key words: intermontane basin, petroleum gelogogy, reservoir-forming stage, petroleum system
