用C18固定相萃取法可从原油中检测出C0-C3酚类。原油中仅有微量的酚类化合物,海相原油中酚类化合物的丰度高于陆相原油,可能指示原始有机质类型较好原油中酚类化合物的丰度偏高。发现陆相、海相不同成因类型原油中酚类化合物总体分布相似,具有相同的化合物种类与峰群分布;但相对分布有一定的差异,陆相原油相对富集长链取代酚(乙基、丙基酚)与多甲基取代酚(三甲基酚),可能体现原始母源的结构差异。烷基酚类化合物可显示与吡咯类含氮化合物类似的运移分馏效应,但控制酚类化合物分布的因素不完全等同于含氮化合物。除了母源、油气运移因素外,原油中烷基酚类化合物的分布还可能与成熟度、油水岩相互作用有关。
C0-C3phenols can be detected from crude oil by C18 stationary phase extraction. Only a small amount of crude oil, phenolic compounds, marine oil phenolic compounds abundance higher than the continental oil, may indicate that the type of the original organic matter better crude oil rich in phenolic compounds. It is found that the total phenolic compounds in the crude oils with different genetic types of continental and marine phases are similar in distribution and have the same compound types and peak groups distribution. However, there are some differences in the relative distribution. The continental oil is relatively enriched in long chain substituted phenols (ethyl, Propyl phenol) and poly (methyl phenol) (trimethyl phenol), may reflect the structural differences of the original parent. Alkylphenols can exhibit similar migration and fractionation effects as azole-containing compounds, but the factors that control the distribution of phenolic compounds are not exactly the same as nitrogen-containing compounds. In addition to maternal and hydrocarbon migration factors, the distribution of alkylphenols in crude oil may also be related to maturity and oil-water-rock interaction.
