摘　　要：通过显微镜反射光及荧光分析研究，认为准噶尔盆地侏罗纪煤系中存在大量的生烃组分。煤系的生烃性与主要生烃组分的多少密切相关。本区存在相当数量的煤有机质类型Ⅱ２型，部分达到了Ⅱ１型，而暗色泥岩多为Ⅲ型和Ⅱ２型。成熟度研究表明，本区煤系已达到或超过生烃门限并产出大量的液态烃。Based on the reflect light and fluorescence analyses under microscope,it is considered that a lot of hydrocarbongenerating macerals exist in Jurassic coal measures of Junggar basin.The characteristics of hydrocarbon generation are correlated closely with the quantities of hydrocarbongenerating macerals.The main organic matter type in Jurassic coal is type Ⅱ2,and some is type Ⅱ1.However,those in dark mudstone are mostly type Ⅲ or type Ⅱ2.The maturity research show that the Jurassic coal have reached of exceeded the “oil window”and generated a large number of liquid hydrocarbon.
