中文摘要：

发展了一种易于操作、经济成本低的原油中萘系物的快速分离技术。色谱质谱检测结果表明，该技术能使原油中萘系物组分得到完整的分离，解决了总芳烃组分色谱质谱分析中由于共溢出现象严重导致的多取代甲基萘参数难以准确获取问题，并为萘系物单分子碳同位素的正确测试奠定了基础。该方法用量少，分离精度高，不仅适用于原油样品，同样适用于其他沉积物有机质样品。作为一个应用实例，对塔里木盆地轮南地区下古生界含油气系统典型原油烷基萘的分布特征进行了初步研究。

英文摘要：

An easy to operate and economic separation of alkylated naphthalnenes from aromatic hydrocarbons in crude oils is reported in this paper. The GC-MS tests show that this method could provide a complete separation of alkylated naphthalenes from crude oils, solving the problem that the maturity parameters of naphthalenes in total aromatics methylated with several methyls are difficult to determine accurately by the GC-MS test because of heavy co-elution and laying the foundation for the free carbon isotope test. This method can be used not only for crude oils but also for other types of sedimentary samples for it can give a complete separation and involving only few sample amounts. As an application, the distribution of alkylated naphthalnenes of some typical oil samples in the petroleum system of Lower Paleozoic in Lunnan region of Tarim Basin was studied elementarily in this paper.
