摘要

摘要: 利用全二维气相色谱—飞行时间质谱技术对石油地质样品进行了分析研究。原油直接进样分析显示原油组分中链烷烃、环烷烃、单环芳烃、双环芳烃和三环芳烃非常有规律地分布在特征区域。化合物鉴别定性准确可靠,能获取原油烃组成的详细特征。和传统色谱分析相比,轻烃分析可实现C₆-C₁₀轻烃组分中的单体烃的分离和识别,能提供更为丰富的轻烃指纹信息。生物标志物多环萜烷的分析可实现高碳数低含量三环萜烷与五环萜烷的分离和识别,伽马蜡烷也得到很好的分离。研究表明全二维气相色谱—飞行时间质谱技术在石油地质勘探研究中有广阔的应用前景。

Abstract: Analysis study to the petro-geology samples was carried out by the technology of comprehensive 2-D GC TOF MS.According to the analysis of original oil,the regulation of the characteristic regions of several groups,namely paraffin,cyclane,monoaromatics,dinuclear and trinuclear aromatics were revealed.With this facility,it is possible to obtain accurate compound identifying and detailed feature of oil sample's hydrocarbon composition.To give more information of the fingerprint of light hydrocarbons,based on the comparison with traditional GC,higher performance on separating and easier re-cognizing of the light hydrocarbon,which are in the frame of C₆-C₁₀,can be achieved by GC×GC.To the biomarkers analysis,it achieved the great separating and easy identifying of tricyclic and pentacyclic terpane,and similarly to the gammacerane.With the high efficiency and performance of the facility,perspective application in the field of petroleum exploration will be done by the GC×GC.
