APPLICATION OF TRIDIMENSIONAL FULL RANGE SCANNING FLUORESCENT SPECTROSCOPY TO MARINE PETROLEUM EXPLORATION

The tridimensional full range scanning fluorescent spectroscopy is a new technique developed in 1980s. The tridimensional spectra are composed of emissive wave length, excited wave length and fluorescent intensity and can be expressed as intensity contours, or digital lists describing the concentration of measured components. This new technique can not only improve the measuring sensitivity and the selectivity of molecular structures, but also can directly measure complicated mixtures. The authors of this paper use this technique and measure the aromatic hydrocarbons extracted from sea-water, marine sediments and marine biota. Applying the ratio "R" between the fluorescent intensities and the fluore-scent intensity of a definite wave length, the geochemical exploration was effectively carried out and provided important informations for the evaluation of regional potential of oil/gas and the prediction of oil/gas type.
