利用荧光光谱进行原油测定及对比的方法

Fluorographic geochemical analysis and its application

利用原油及烃源岩抽提物中的芳烃在紫外光下能发荧光的特点 ,根据其荧光主峰波长及油性指数的差异判断原油性质 ,并且将荧光谱形、主峰位置及油性指数相结合 ,还可进行油油对比和油岩对比。这种新型的地球化学分析方法是利用荧光分析仪来完成的 ,方法简单、快速、准确 ,具有普遍推广的意义。

In group compositions of crude oil and hydrocarbon extracts, the composition, which is mainly composed of aromatic hydrocarbon, can give fluorescent light under ultraviolet light. Researchers can quickly and exactly get fluorescence spectrum curves and the peak value of analytical samples by fluorescence analyzer, can decide crude properties according to the fluorescence peak values and differernces of crude property indexes, and also can make oil oil correlation and oil rock correlation by combination of fluorescence spectrum curves and the peak value with crude property indexes. Fluorographic geochemical analysis is a simple, quick and exact analytical method.
