| 摘 要： | 采用最新引进的国际八十年代后期开发的GC-deltas气体同位素质谱仪,对几类典型烃源岩的热模拟液态烃产物-热解油进行了GC/C/MS在线(Online)碳同位素分析,获得了有关轻烃单体、正构烷烃及姥鲛烷、植烷分子的碳同位素组成数据.分析资料表明,轻烃单体、正构烷烃及姥鲛烷、植烷的碳同位素特征及分布模式能够有效地反映烃源岩的特征-母质类型、沉积环境及热成熟度等.

| Abstract: | Data of carbon isotope composition of relevant light hydrocarbon monomers, n-alkanes, pristane and phytane are acquired from an online analysis of GC/C/MS of liquid pyrolyzate of some typical source rocks using GC-dalta S gas-MS. The data suggest that the characteristics and distribution model of the carbon isotope of light HC monomers, n-alkane, and pristane and phytane can reflect effectivelythe features of source rock, such as the type of its precursor,sedimentary environment,geological age and thermal maturity. Therefore,it implies a possibility of application of the data in oil and gas geochemical study. |
