[Study on the characteristic and significance of synchronous fluorescence spectrum of crude oil and nature gas samples].

Based on studying characteristic of constant-wavelength synchronous fluorescence spectrum of various kinds of crude oils and nature gases from the large fields of our nation, the similar peak and characteristic peak of various crude oils and nature gas were proposed. This approach has several advantages, including narrowing of spectral bands, simplification of conventional fluorescence spectra, contraction of the spectral range and so on. The technique can be used not only in judging oil and gas layers, types of crude oil, but also in providing the arms of petrolium exploration. In fact, the synchronous fluorescence spectrum and the three dimensional fluorescence spectra are the same in essence. The more achievement will be obtained by replacing the three dimensional fluorescence spectra analysis with the synchronous the fluorescence spectrum analysis.
