在原油或者岩石抽提沥青"A"经过硅胶—氧化铝柱层析后得到的饱和烃馏分中加入内标物,然后进行生物标志化合物GC-MS定量分析研究。实验结果表明甾烷和藿烷化合物的定量分析误差小于10%。应用此定量方法对岩石热模拟排出油中的生物标志化合物进行GC-MS定量分析。结果表明随着模拟温度的增高生物标志化合物含量逐渐降低,但在350℃后基本稳定;Ts/(Ts+Tm)值随着模拟温度的增加而提高。

Added Internal standard sample to the saturated hydrocarbon fractions which are obtained through silicon-alumina column chromatography in crude oil or extraction asphalt "A",then carried out the GC-MS quantitative analysis of biomarkers.The results indicate that quantitative analysis errors of the steranes and hopanes are less than 10%.This method is applied to the GC-MS quantitative analysis of biomarkers for expulsive oils during thermal simulation of rocks.The results show that the contents of biomarkers gradually decrease with the rising of simulation temperature,but the situation is basically stable after 350℃.The ratio of Ts/(Ts+Tm) increases with the rising of simulation temperature.
