摘要
在三维荧光光谱研究的基础上，采用化石燃料非线性可变角扫描荧光特征光谱技术，列出了各类化石燃料（煤、石油、天然气）的荧光图谱模式，并赋予量值化指标，划分了各类化石燃料的参数范围。这些模式和指标反映了各环芳烃的荧光性质，并突出了利于鉴别各种样品的关键峰位。对图谱考察可见，化石燃料样品除在波长340urn处有明显峰外，在328urn处也有峰出现，同时，依照天然气→凝析油→轻质油→重质油→煤的顺序，图谱的重心逐渐红移，轻组分递减，重组分递增。按照图谱的特征，便可迅速判断样品的基本类型，为油-由、油-气、油-煤对比及油-气-煤对比提供依据。
Based on studying characteristics of three dimensional fluorescence of fossil fuel, the development of non-linear variable-angle synchronous scanning fluorescence spectrum is reported.This technique can provide a method for generating diagnostic profiles of various fossil fuels, such as coal, oil and nature gas. The profile patterns of them are presented. The characteristics of various profile patterns can be expressed by some indexes, which is favorable to correlations of oil/oil, oil/gas and oil/coal. This technique has a potential application to geochemical exploration of oil and gas.
