有机岩石学方法是研究煤成油的重要方法之一。显微镜下反射光及荧光分析研究认为，准噶尔盆地侏罗纪煤中存在大量的生烃组分，大部分基质镜质体都发一定强度的荧光。煤的生烃性与主要生烃组分的含量密切相关。本区相当数量的煤有机质类型为Ⅱ２型，部分为Ⅱ１型。成熟度研究表明，本区侏罗纪煤已达到或超过生烃门限并产出大量的液态烃，是准噶尔盆地重要的烃源岩之一。 Organic petrology is one of the important methods to study coal oil formation. Under the microscope, reflected light and fluorescence analysis suggest that there are a large number of hydrocarbon generation components in the Jurassic coal in the Junggar Basin, and most of the matrix vitrinites emit a certain intensity of fluorescence. The hydrocarbon generation of coal is closely related to the content of major hydrocarbon generating components. The amount of coal organic matter in this area is type Ⅱ2 and partly type Ⅱ1. Maturity studies show that the Jurassic coal in this area has reached or exceeded the hydrocarbon generation threshold and produced a large amount of liquid hydrocarbons, which is one of the important source rocks in the Junggar Basin.
