生标新技术在塔河油田托甫台和盐下地区的应用

Application of New Biomarker Technology in Tuofutai and Yanxia Areas of Tahe Oilfield

选取塔河油田托甫台和盐下地区共14口井的原油样品,对其进行了二维色谱/飞行时间质谱和色谱-质谱-质谱分析,研究了不同油样的烃类组成特征、原油类异戊二烯烃特征以及断代生物标志物特征(C26降胆甾烷和C30甲基甾烷系列化合物)。研究发现,新技术同常规的色谱和色谱-质谱方法相比,具有很大的优势,其分析结果更加真实可靠;同时,能检测到多个与时代相关及特定物种的生物标志物,为油源对比提供有利依据。

The oil samples are chosen from 14 wells in Tuofutai and Yanxia Areas of Tahe Oilfield,2Danalysis is carried out by using GC×GC and GC-MS-MS technologies.The characteristics of hydrocarbon compositions,the isoamyl alkadiene of oils and age-related biomarkers(the series compound of C26 norcholestane and C30 methyl sterane)are studied.Compared with conventional GC and GC-MS technologies,the new technology has more advantage and its analysis is more true and reliable.Meanwhile,multiple series of age-related and taxon specific biomarkers are tested by using the technology.It provides favorable basis for oil and source rock correlation.
