| 中文摘要:准噶尔盆地东部吉木萨尔凹陷及博格达山前凹陷发育3个含油气系统，3个含油气系统在形成过程中共享某些成藏地质条件，构成一藏多源、一源多藏的复合含油气系统。各含油气系统多期生烃、成藏和改造时刻构成复合含油气系统的多个关键时刻。复合含油气系统油源充足，成藏条件匹配良好，形成几个有利的油气聚集带。区域构造演化对烃源岩演化、复合含油气系统的形成有一定的控制作用。 |

| Characteristics and Evolution of the Composite Petroleum System in Jimsar Depression, Eastern Junggar Basin |
|
|
| Abstract:There exist three petroleum systems in Jimsar depression of eastern Junggar Basin and its adjacent Bogda piedmont depression. They together shared hydrocarbon pool-forming conditions and formed a composite petroleum system. An analysis of characteristics and evolution of source rocks and petroleum systems suggests that, with fairly good matching of pool-forming conditions, the composite petroleum system is petroliferous. Multi-source and multi-phase hydrocarbon generation and multi-phase pool formation of every petroleum system restrict the critical moments of the composite petroleum system. Having pointed out advantageous hydrocarbon-bearing units, this paper deals with the relationship between the regional tectonic evolution and the formation of the composite petroleum system. |
