Abstract
According to the contour maps of the three-dimensional fluorescence spectra of non-quenching crude oil samples, we have found the common and diverse f luorescence characteristics of various crude oils. The common fluorescence characteristic is that the main peaks of various crude oils are located in around the position of excitation/emission wavelength pair 228nm/340nm. The diversity of fluorescence characteristics can be represented with several indexes alpha, K, F and R, and these indexes provide measurable parameters for division of fluorescence fingerprints of crude oils. The fluorescence f ingerprints of crude oils can be divided into three models named O, B and Q that are corresponding to condensate oil, light oil, and heavy oil respect ively.
