摘要
在分析原油芳烃谱图特征的基础上,对切割制备的各特征峰组宽标样进行了荧光光谱的同步扫描,得知其与芳环数的关系,从而将原油芳烃划分为轻芳烃、中芳烃和重芳烃三个组分。提出芳烃“A”值这一表征芳烃组分性质的指标。经回归分析,表明此值与原油的物理性质及化学组成密切相关。在此基础上,将原油划分为三种类型。随着地层的由老到新,其所含的芳烃组分具有由轻到重的变化趋势。
A method using reversed-phase high performance liquid chromatography to analyze aromatic hydrocarbons tin crude oil has been established.Sample cats were prepared based on fluorescence spectra.According to the numbers of aromatic rings,the aromatic hydrocarbons of curde oil are divided into three groups;the light,the medium and the heavy aromatic hydrocarbops.The value 'A' of aromatic hydrocarbons,which is closely related to the physical properties and chemical natures of the crude of has been proposed,Consequently crude oils also can be classified in*o three types.In comparing the valve 'A' of aromatic hydrocarbons in crude ools from different oil-bearing strata,a preliminary rule has beep obeyed i.e.the aromatic hydrocarbons tends to be lighter as the geological age of the crude oil-bearing is older.
