本文主要讨论生油岩氯仿抽提物及原油中沥青质和胶质的化学组成和结构特征.作者以高效液相色谱法,将沥青质和胶质分离分析为中性、弱极性及极性三个组份,并对三个组份进行元素分析、红外光谱分析及氢谱核磁检测.实验表明,沥青质三个组份随极性的变化,其芳香度有明显的差异;胶质三个组份则表现为杂原子取代度和芳香度的差异.这些特征与生油岩的母质类型和成熟度有关.

The characters of chemical composition and structures of the asphaltene and resin of chloroform rock extracts and crude oils are discussed.Using high performance liquid chromatography,asphaltene and resin are respectively separated into three components,i.e.neutral,weak polar and polar.Furthermore,element composition,infra-red spectrum and hydrogen nuclear magnetic resonance are analysed for these three components.Experiments show that the aromaticity of the asphaltene components evidently increases with the the polarity,while differences in hetero-atom-substitution and aromaticity exist among the three resin components.These features are all related to the types of the precursor and maturity of source rocks.
