摘要:
采用气相色谱-质谱的方法对胜利油田的原油组分进行了定性分析,同时利用碳优势指数、主碳峰和姥鲛烷与植烷的浓度之比等参数对原油指纹信息进行分析。通过组分分析,共定性了原油中的103种化合物,其中饱和链烷烃的质量分数为89.86%。通过指纹信息分析,确定了胜利油田原油的成熟度高(碳优势指数=1.026 7),母质类型好。原油沉积环境属于海相还原沉积环境(姥鲛烷与植烷之比<1)。

Abstract:
The components of crude oil produced in Shengli Oilfield were analyzed qualitatively using Gas Chromatography-Mass Spectrometry(GC-MS). Some indices, such as CPI, Cmax, and Pr, were employed to analyze the fingerprints of the crude oil. 103 kinds of components were identified by the qualitative analysis, and the mass fraction concentration of saturated paraffinic hydrocarbons was accounted for 89.86%. The analysis of the fingerprint information indicated that the evolution degree of the crude oil produced in Shengli Oilfield is high and its type of source is good. The sedimentary environment of the crude oil belongs to the marine and reducing condition.
