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，Ｖ，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
The trace element contents of six crude oils in Liaohe Fault Depression were analyzed by plasma mass spectrometry. The content of trace elements in crude oil is low, only Ni, V and Li are higher, the V / Ni ratio of crude oil is 0-02 ~ 0-04, which is lower than the V / Ni value of world crude oil, reflecting that the source area is depleted Mantle. The total amount of rare earth elements in crude oil is also low, and the REE distribution curve of Hai 13 39 oil is horizontal with the features of mid-oceanic ridge basalt
