三塘湖盆地是新疆东部地区北西向盆地构造带的一部分,经历了一系列的构造运动,形成了三套烃源岩。利用地球化学方法对三套烃源岩进行生烃潜力评价,主要从有机质丰度、有机质类型和有机质成熟度三个方面进行分析。通过分析表明,大多数烃源岩处于未熟-低熟阶段,有机质类型以Ⅲ型为主。
The Santanghu Basin is a part of the NW-trending tectonic belt in the eastern part of Xinjiang. It experienced a series of tectonic movements and formed three sets of source rocks. The geochemical method was used to evaluate the hydrocarbon generation potentials of three sets of source rocks, mainly from three aspects of organic matter abundance, organic matter type and organic matter maturity. The analysis shows that most of the source rocks are in the immature - low maturity stage, and the type of organic matter is mainly type Ⅲ.
