烷烃组份是原油和沉积岩普遍含有的稳定成分之一,它的组成特点与石油原始有机质的性质密切相关,并随有机质的成熟演化而明显地呈现规律性变化。因此,借助色谱分析技术,对它的组成特点进行研究,对于在油气勘探中搞清有机质的性质和成熟演化特点,鉴别生油岩,对比油源及研究油气运移,均可提供宝贵的资料。目前,饱和烃色 Alkane is one of the stable components commonly found in crude oil and sedimentary rocks. Its compositional characteristics are closely related to the nature of petroleum’s original organic matter, and obviously change regularly with the maturation and evolution of organic matter. Therefore, by means of chromatographic analysis, its compositional characteristics are studied. It can provide valuable information for understanding the nature and mature evolution characteristics of organic matter in oil and gas exploration, identifying source rock, comparing source of oil and studying hydrocarbon migration . At present, saturated hydrocarbon color
