Abstract Based on study on the characterization of three dimension and constant-wavelength synchronous fluorescence spectra,the similarity and characteristic peaks of various crude oils and natural gases have been proposed.The types of crude oils and natural gases can be identified by three-dimensional contour spectra.Three-dimensional contour spectra and constant-wavelength synchronous fluorescence spectra can be used in judging polluted samples of synthesizing well log by the wavelength and intensity of the emission peaks.The constant energy synchronous fluorescence spectroscopy offers the advantages of greater sensitivity and selectivity for marine sediments, which contain ample aromatic hydrocarbon molecules,than the constant wavelength synchronous fluorescence spectroscopy.In addition,the geological information must be considered when the analytical date is applied.
