| 摘 要： | 烃源岩中存在大量矿物沥青基质，目前对其成烃潜力知之甚少。本文以酒东盆地侏罗系和白垩系烃源岩为例，从矿物沥青基质与有机显微组分，无机矿物、有机质丰度、有机质类型，有机质成熟度的关系及其荧光变化特点探讨其组成及成烃潜力，结果表明，矿物沥青基质中有机质含量低，且以次生有机质为主，原生有机质含量较少，成烃潜力有限。

| Abstract: | There is a large number of mineral-bituminous matrix (MBM) in the potential source rocks, and its hydroearbon potential is still uncertain. This paper discusses the possible composition and hydrocarbon generation potential of MBM, based. on the relationship between concentration of MBM and inorganic mineral, organic macerals,and abundance, kerogen type and maturity of organic matter, and fluorescence intensity alternation of sporenite, taking Jurassic and Cretaceous source rocks in the eastern Jiuquan basin as an example. The results indicate that MBM is dominated by inorganic minerals and the conceritration of organic matter is low. The original organic matter is minor and secondary organic matter is major in MBM. Therefore, the potential of hydrocarbon generation of MBM is low. |
