| 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。

| Abstract: | 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. |
