新疆三塘湖盆地侏罗系烃源岩的显微组分组成及生烃组分剖析

Composition and Hydrocarbon generation Macerals of Jurassic Source Rocks in Santanghu Basin, Xinjiang Province

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。

Using whole rock analysis technique for organic petrology,the composition and hydrocarbon generation of macerals in the middle and lower Jurassic coal bearing source rock,Santanghu basin of Xinjiang,are studied in detail Macerals of the source rock are rich in vitrinite and lack of sapropelite, indicating an absolute dominance of terrestrial organic matter from higher plant The maceral content and composition in each interval are different from each other,showing Badaowan formation is a main source bed Sporinite and cutinite is one of the most significant hydrocarbon generating matter for coal derived oil The exsudatinite and micrinite give an evidence for hydrocarbon generation in this district
