| 摘 要： | 研究表明,不同沉积环境湖相的低熟原油芳烃生物标志物分布具有较大的差异。淡水湖相低熟原油芳烃以萘和菲系列化合物为主要组份、膏岩盐湖相低熟原油芳烃以脱羟基维生素Ｅ和三芳甾烷为主要组份、盐岩湖相低熟原油芳烃则以三芳甾烷为主要组份、其它生物标志化合物组份的相对丰度均较低。本次研究的低熟原油芳烃中普遍检测出明显的苯并藿烷系列化合物、盐湖相低熟原油芳烃中还检测出藿烷酮化合物,表明该地区古环境中细菌、微生物发育

| Abstract: | ? arotanes
with two aromaticrings (M=546,B.P m/z134)and alkyl benzene compounds with an isoprenoid
side chain (m/z 134 and m/z 120 as base peaks) are also detected out in the studied
samples.They are one of the sources for the rich phytane and lower carbon numbered
isoprenoids in the low mature crude oil in this area.In the salt environment,they may have an
even higher relative abundance,especially for phytane in saturated fractions. |
