| 中文摘要 | 对两种原油进行混合配比实验,将混合后油样置于人工气候箱进行风化模拟实验,采用气相色谱质谱联用仪(GC-MS)检测风化样品中的生物标志化合物,短期风化作用对混合溢油的油指纹、生物标志化合物诊断指标等的影响。结果表明,混合溢油的正构烷烃总质量变化与单一原油油品的变化规律相近,即前期风化较快,质量减损较多,而后期风化趋缓,不同混合比例的溢油表现差异不明显。常用于短期风化的诊断比值对各混合油样的风化具有指示意义,但难以定性鉴别油品是否发生混合。重复性限法检验只能判定短期风化过程前后的油样为同一油源,而难以反映油样是否为混合油源的特征,各诊断比值的RSD%值较大可能是混合溢油的一个表现。 |
| 英文摘要 | Two kinds of oils obtained from different sources were mixed together at different ratios, and tested. The composition changes of mixed oils at molecular level by simulating weathering conditions in static seawaters placed in an artificial climate chamber were investigated. The results show that similar with single crude oil, during the 15 weathering days, the mixed oils showed a significant loss of crude oils mainly during the first, while the loss significantly reduced during the rest of time. The conventional biomarkers Pr/Ph, Pr/n-C_(17), Ph/n-C_(18) and CPI_1 can be used to indicate the short-term weathering of almost all mixed oils, while these biomarkers cannot be used to identify weather the oils have been mixed or not. Repeatability limit analysis method can be used to detect whether oil samples before and after short-term weathering processes came for the same source of oil or not, but it is difficult to reflect whether the oil samples were mixed or not. High RSD% value of diagnostic markers of one of oil samples may be a manifestation that spill oils are a mixture. |
