【摘要】 选取渤海3个不同区块不同平台的原油样品,进行室内蒸发风化模拟实验。采用气相色谱法和气相色谱-质谱联用法,分析了在不同风化程度(最大风化、最大风化的1/3、最大风化的2/3)下正构烷烃、生物标志化合物以及用于溢油鉴别的诊断比值在风化过程中的变化特征,探讨了渤海不同原油的蒸发变化过程,对渤海溢油鉴定具有重要的借鉴作用。更多还原

【Abstract】 We choose three kinds of crude oil from different oil platforms in Bohai Sea to run a simulant evaporation weathering experiment.Oil fingerprint change rules of n-alkanes and biomarkers of the three kinds crude oil were studied at different weathering degrees(the Max weathering,1/3 of the Max weathering,2/3 of the Max weathering) and the stabilities of diagnostic ratios were also investigated by GC and GC/MS.We can know the rule of the crude oil evaporation weathering in Bohai Sea.更多还原
