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 fluorescence 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 α, K, F and R, and these indexes provide measurable parameters for division of fluorescence fingerprints of crude oils. the fluorescence fingerprints 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 respectively. |
