本文根据沥青质的有机元素组成、红外光谱的基团特征及核磁共振波谱的研究,提出了沥青质的结构组成与母源有机物质的原生性质密切有关,并可以提供母质分类的多种有用信息。一、样品与实验样品:选择了我国中新生界陆相湖盆代表性的生油岩,以不成熟生油岩为主(镜质体反射率小於0.7％)。所研究的样品包括泌阳凹陷下第三系、辽河断陷下第三系以及陕甘宁盆地侏罗系、三迭系的不同深度主要生油岩27块。
In this paper, based on the composition of organic elements in asphaltene, the characterization of IR spectra and NMR spectroscopy, we conclude that the structural composition of asphaltene is closely related to the native properties of maternal organic matter and provide useful information on the classification of parent materials . First, the samples and experimental samples: The selected source rocks in the Mesozoic-Cenozoic continental lacustrine basin are dominated by immature source rocks (vitrinite reflectance less than 0.7%). The samples studied include the Lower Tertiary in the Biyang depression, the Lower Tertiary in the Liaohe fault depression, and the 27 primary oil source rocks of different depths in the Jurassic and Triassic series of the Shaan-Gan-Ning basin.
