摘要

用等离子质谱方法分析了辽河断陷6 个原油的微量元素含量。原油中微量元素含量较低

仅Ni

Li 等较高

原油的V/Ni 比值为0.02～0.04

低于世界原油的V/Ni 值

反映了源区为亏损型地幔。原油的稀土元素总量也低

海13-39 原油的稀土配分曲线呈水平分布

具洋中脊玄武岩特征。

Abstract

Trace element contents of six crude oil samplesin Liaohe Depression are analysed by IPC-MS.The results show thatexcepting Ni

thet race element contents of crude oils are very low

V/Ni ratio is 0.02～0.04

which is lowerthan that of the world oils.Crude oils can reflect the deficite geologic tectonic environment.The very low ratio of Liaohe crude oils might relateto depletion mantle.The rare earth element contents arelow.The REE distribution curve of Hai 13-39 crude oil suggests that it is related to mid-ocean ridge basalts.
