摘要
该文以渤海原油SZ36-1为研究对象进行综合模拟风化实验,探讨了原油中生物标志物及5类多环芳烃(PAHs)组分的分布情况及风化规律。结果表明:经过30 d风化,渤海原油SZ36-1中大部分生物标志物表现出强的稳定性,部分PAHs的分布发生较大改变,其中萘系列化合物损失最严重,相对浓度的损失达80.34%;菲、二苯并噻吩、、芴系列则相对稳定;经t检验分析风化样品测试数据,生物标志物诊断比值表现出良好的稳定性,所选取多环芳烃新诊断比值中,菲和系列、烷基取代二苯并噻吩类、烷基取代芴类的抗风化能力较强,可用于油源鉴别。
The weathering disciplinarian of the biomarkers and polycyclic aromatic hydrocarbons(PAHs) in the crude oil named SZ36-1 from Bohai Sea was investigated under the comprehensive simulating weathering.The results showed that most of the biomarkers kept good stability,but the distribution patterns of some PAHs in crude oil changed a lot after 30 days of weathering.Naphthalene(NAP) series of compounds had the most serious loss and the loss of the relative concentration reached to 80.34%,while the proportion of phenanthrene(PHE) series,dibenzothiophene(DBT) series,chrysene(CHR) series and fluorene(FLU) series remained relatively stable.The diagnostic ratios of biomarkers keep relatively stable.Among the selected new diagnostic ratios from PAHs,the phenanthrene series,chrysene series,alkyl dibenzothiophene series and alkyl fluorene series had strong weathering-resistant capabilities,and could be used for the identification of oil source.
