摘要
芳烃化合物是烃源岩和原油中非常重要的有机族组分,与饱和烃一样含有丰富的地球化学信息。应用GC-MS能检测到的芳烃化合物可分为常规多环芳烃、含NSO杂环芳烃、芳香甾萜烷及脱羟基维生素E。它们的一些参数可作为母质来源、热成熟度、沉积环境和油气运移判识的有效指标,是饱和烃地球化学研究的重要补充和佐证,对油气勘探与开发有重要的实际意义,但生物降解、混源油等因素会影响这些参数的正确性。应用全二维气相色谱-飞行时间质谱仪(GC×GC-TOF)对生物降解油芳烃中的鼓包化合物UCM(unresolve dcomple xmixtures)进行探索性研究取得了一定的效果,这也将是今后芳烃研究的重要方向。
Aromatic hydrocarbons are one of the most important fractions of petroleum and sediment solvent extracts,which contain abundant geochemical information.They can be divided into regular polycyclic aromatic hydrocarbon,NSO heterocyclic aromatic hydrocarbon,aromatic steranes,aromatic terpanes and dehydroxytocopherol.Some of parameters in the aromatics are also very effective in petroleum exploration and development,such as origin of organic matter,thermal maturity,depositional environment,oil source correlation and migration.Hence,the aromatics are significant for the petroleum exploration and development.However,some parameters are not correct by effect of biodegradation and mixed oil.At present,the UCM（unresolved complex mixtures） of aromatic of biodegraded oil have shown some effects by comprehensive two-dimensional gas chromatography time-of-flight mass spectrometer（GC×GC-TOF-MS）.It will be an important direction on aromatics study in the future.
