[Study on the characteristic and significance of three dimensional fluorescence spectra of petroleum samples].

Based on studies on the characteristics of three dimensional fluorescence spectrum of a kinds of oils and gases, we found the similarity peak and characteristic peak for the various crude oils and nature gases. This technique can be used not only in judging the types of crude oil and gas, but also in the comparison of oil to oil and oil to source, and studying what oil and gas stemmed from and its organic geochemistry as well. The true of sample is very important due to the volatility and alterability of light aromatic hydrocarbon. Once solving the quantification of fluorescence analysis, the evidence may be provided for predicting oil and gas layers, source rock.
