运用有机岩石学全岩分析方法,对新疆三塘湖盆地中、下侏罗统煤系烃源岩进行了显微组分组成与生烃组分剖析。三塘湖盆地烃源岩显微组分中富含镜质组、贫腐泥组,明显具有高等植物陆源有机质占绝对优势的特点。显微组分含量与组成在各层段中呈现不均衡性,八道湾组为该区的主力烃源岩,孢子体和角质体是煤成油的最主要的生烃组分,渗出沥青体、微粒体的出现为该区烃类生成提供了证据。
Based on the whole rock analysis method of organic petrology, the microscopic composition and hydrocarbon generation composition of the Middle and Lower Jurassic coal measures of source rocks in the Santanghu Basin, Xinjiang were analyzed. The source rocks in the Santanghu Basin are rich in vitrinite and poor-lean mudstones in their microscopic components and obviously have the characteristics that the terrigenous organic matter of the higher plants occupy an absolute predominance. The content and composition of the micro-components show an imbalance in each interval. The Badaowan Formation is the main source rock in this area. The sporophyte and the keratoplast are the major hydrocarbon-generating components of coal-forming oil. The presence of microsomes and microsomes provided evidence for hydrocarbon generation in this area.
