透射光-荧光下干酪根有机显微组分的划分

Classification of the macerals of kerogen in hydrocarbon source rocks by transmitted light fluorescence.

针对目前国内外烃源岩有机质分类的研究现状，以有机岩石学研究为核心，运用透射光荧光分析手段，通过对国内外大量样品的镜下观察分析，结合有机地化和有机质的成因、来源分析，并考虑生烃贡献，建立了烃源岩干酪根有机显微组分的一种新的分类方案，将无定形体进一步划分为腐泥无定形体和腐殖无定形体，将镜质体进一步划分为正常镜质体和荧光镜质体。该分类方案在科研和生产中的应用效果较好。

In view of existing research into the macerals of kerogen and classification in hydrocarbon source rocks, the authors proposed a new classification of the macerals of kerogen in hydrocarbon source rocks on the basis of analyses of a large number of samples by transmitted light fluorescence microscopy. This is also a combination result of analyzing organic geochemistry, the origin of organic matter and the potential of hydrocarbon generation. Amorphogen is further divided into sapropelic amorphogen and humic amorphogen, and vitrinite into normal vitrinite and fluor vitrinite in this paper. It is satisfactory that these results are applied in all respects of source rock evaluation.
