摘要： 塔里木盆地含油气系统具有多源叠加复合、油气普遍混源、形成含油气系统的关键时刻多、成藏期次多和含油气系统多的特点。根据含油气系统形成的构造背景与烃源岩叠合分布特征及油气源对比结果,将塔里木盆地划分为克拉通型、前陆型和克拉通-前陆叠合型3类10个含油气系统。其中库车、塔西南油气系统为已证实的两个前陆型含油气系统,成气条件十分优越。轮南-草湖、哈拉哈塘、塔中、巴楚-盖麦提油气系统为已证实的海相克拉通型含油气系统,是塔里木盆地海相油气聚集的最有利区。塔东、阿瓦提油气系统则属克拉通-前陆叠合型含油气系统。

Abstract: Petroleum systems in the Tarim basin are of the typical characteristics of superimposed basins. There exist multiple source rocks, hydrocarbon kichens, critical moments,periods of accumulation as well as multiple petroleum systems. The petroleum systems can be divided into cratonic,foreland and craton-foreland superimposed types and 10 petroleum systems are discerned. The Kuche and Southwestern Tarim are proved foreland petroleum system with excellent conditions for natural gas generation and accumulation. The Lunnan-Caohu, Halahatang, Central Tarim,Bachu-Maigaiti are proved cratonic petroleum systems favorable to marine oil and gas accumulation. The East Tarim and Awati belong to craton-foreland superimposed petroleum systems.

Key words: Tarim basin, foreland basin, cratonic basin, petroleum system, superimposed petroleum system
