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 results of organic geochemistry and organic petrology show that the Jurassic coal in the Santanghu Basin, Xinjiang, is rich in sporophytes and keratoplasts (3.0% -6.0% of the volume fraction of the whole rock) The higher total hydrocarbon fraction (30% -50%) and saturated aromatic ratio (0.6-3.0) in the “A” composition had an effect. The coal accumulation environment is the key factor that affects the microscopic composition of coal and oil generation characteristics. The Jurassic coal in the Santanghu Basin belongs to the “Late Late Rows” superimposed with source rocks of the “Early Early Early Paid”.
