正烷烃单个化合物碳同位素分布初探

Preliminary Study of Stable Carbon Isotope Composition of Individual n-alkanes

本文采用气相色谱—碳同位素比值质谱仪研究了生油岩热模拟液体产物等样品中正烷烃的单个化合物碳同位素分布与特征,初步探讨了此项新技术在石油有机地球化学研究中的应用前景.

In this paper, distribution of the stable carbon isotope composition of individual n-alkanes. that analysed by GC / IRMS, was studied preliminary. There are five type of samples. Pj, Ps and PY expelled by thermal modelling; L extracted and L-HC1 released by hydrochloric acid from the carbonate rock (In Table 1) . And the Authors explored the uses of GC / IRMS for correlation, migration, thermal history ana lysing and sedimentary environment of source rocks.
