摘要：
The polyaromatic compositions of 12 Egyptian crude oil samples from the Western Desert and Gulf of Suez regions were analyzed using gas chromatography in conjunction with sulfur-selective atomic emission detection. The results show the variation in distributions of benzothiophenes and dibenzothiophenes in oils with different maturity levels. The ratio of benzothiophenes to dibenzothiophenes has been applied successfully as tool to evaluate maturity changes where it correlates well with other maturity parameters. A cross-plot of benzothiophenes/dibenzothiophenes versus isoprenoid/n-alkane ratios consistently classified oils according to their maturity rank.
