摘要

摘要: 对孤岛原油中的可溶有机质生物标志化合物进行了气相色谱—质谱分析,结果表明,该原油受到了严重的生物降解,部分用于对比的生物标志物受到了破坏,致使有关参数值发生了变化,给油—油对比、油—源对比带来了困难。采用超声萃取技术,分离出沥青质包裹体中抗生物降解的生物标志物,并与原油中的生物标志物进行对比。其结果显示沥青质包裹体组分与原油组分的甾、萜烷非常相似,C₂₇,C₂₈,C₂₉规则甾烷类分布均呈"L"型,而与生物降解程度无关,表明此方法可完全用于强烈生物降解原油的油—油对比和油—源对比研究,在有机地球化学领域的研究中具有重要的指导意义。

Abstract: The analysis on soluble organic matters from the crude oils of the Gudao Oilfield showed that the severe biodegradation have been taken place,and some biomarkers are not used to make oil—oil correlation and oil—source correlation.The ultrasonic wave technology was used to extract biomarkers from the asphaltene inclusions of the crude oils which are not susceptible to be biodegraded and compared with crude oils.The results showed that the steranes and terpanes of the asphaltene inclusions and the crude oil are very similar.Especially,the distributions of C₂₇,C₂₈,C₂₉ steranes are all "L" shaped in the crude oils and the asphaltene inclusions.Hence,the technology of extraction of asphaltene inclusions by ultrasonic wave can be successively applied to make oil—oil correlation and oil—source correlation of severely biodegraded crude oils.
