摘要
有机地球化学和有机岩石学研究结果表明，新疆三塘湖盆地侏罗系煤中富集孢子体和角质体（３．０％～６．０％，全岩体积百分比），对煤中氯仿沥青“Ａ”组成中较高的总烃馏分（３０％～５０％）和饱芳比（０．６～３．０）产生了影响。煤的聚集环境是影响煤的显微组分组成及生油特性的关键因素。三塘湖盆地侏罗系煤属于“晚生晚排”叠加有“早生早排”类型的烃源岩。
The high content hydrocarbon(30 50%) and high saturate aromatic ratio (0 6 3 0) in the extracts from the Jurassic coal in Santanghu basin, Xinjiang, are virtually different from that of coals in other basins Organic petrological and geochemical parameters show that sporinite and cutinite with a higher content (3 0 6 0%) directly influence extracts and the oil generating characteristics of coal The accumulation environment of coal is a key to control the content and preservation of sporinite and cutinite in coal The Jurassic coal from Santanghu basin belongs to late oil generating expulsion type source rock superimposed by early oil generating expulsion
