| 摘 要： | 芳基类异戊二烯化合物被认为是高盐和强还原沉积环境中沉积有机质芳烃馏分中的特征性生物标志物。本文在对采自我国三个典型陆相油气盆地的33个原油和生油岩样品芳烃馏分中的生物标志化合物进行了详细研究的基础上，着重讨论了鄂尔多斯盆地中生界-原油样品中芳基类异戊二烯系列化合物的检出及其在指相上的地球化学意义，指出该系列化合物还可指示微咸水和还原的沉积环境。

| Abstract: | Aryl isoprenoid compounds in the aromatic fraction of sedimentary organic matter have been regarded as a biomarker that indicates a saline and strongly reducing sedimentary environment. On the basis of the detailed study on biomarker compounds in the aromatic fraction of 33 crude oils and source rocks collected from three typical terrestrial sedimentary basins in China, this paper discussed an aryl isoprenoid serial compound detected out from a Mesozoic crude oil in the Ordos basin and its geochemical significance in indicating sedimentary facies. It was proposed that this serial compound could also be an indicator to a brackish and reducing sedimentary environment. |
