摘要: 原油全烃色谱分析可将原油中正构烷烃间的绝大部分异构体分离开 ,进而将原油的细微差异区分开。分析对比相同和不同成因类型的原油及源岩中分子量烃(主要是 C8~C14)特征 ,指出不同成因类型的原油指纹差异大 ,而相同成因的原油指纹相似。分析了生物降解程度不同的原油指纹特征 ,初步建立一些可反映生物降解程度的中分子量烃化合物。以大港油田港东地区为例 ,研究中分子量烃在油/油及油/源对比中的应用。

Abstract:

Most compounds among normal paraffin of oil can be separated by total hydrocarbon chromatography analysis as to distinguish the subtle differences in the crude. The middle molecule hydrocarbon in the crude and source rock with sameor different formation of cause is analyzed and correlated. Thefingerprint of the different genetic oil and source rock in different area are
studied in thepaper , the result shows that fingerprint difference of the different genetic oil is very obvious, while same genetic oil fingerprint is similar. Some low carbon compounds susceptible to biodegradation are also studied in the paper. Taking Gangdong oil field as example , the authors makeoil/ source correlation using middle molecule hydrocarbon.

Key words: total hydrocarbon chromatography, middle molecule hydrocarbon, biodegradation, oil/ source correlation.
