Fluorescence spectrometry is commonly used to determine polycyclic aromatic hydrocarbon and evaluate the migration of oil and gas as well as the properties of base oil. Lying in western China , Xinjiang is almost covered with snow in winter. According to the geographical climatic environment in combination with the low detection limit and high sensitivity of fluorescence spectrometry, the authors analyzed the snow and the soil below it along a profile in a known oilfield in Xinjiang by means of fluorescence spectrometry. The results of two-dimensional fluorescence spectra, constant-wavelength synchronous fluorescence spectra and three-dimensional fluorescence spectra are compared with each other and discussed in detail. The comparison results shows that snow can quite effectively adsorb the polycyclic aromatic hydrocarbon and have an abnormal indication for the oil and gas reservoir. These findings can provide some reference for the exploration of oil and gas reservoirs in unknown geographical climatic environment areas in the future.
