原油样品的三维荧光光谱特征研究

Study on the Characteristic and Significance of Three Dimensional Fluorescence Spectra of Petroleum Samples

在分析大量油气的三维荧光光谱的基础上 ,提出了油气的共性峰和气、不同性质原油的特征峰。将三维荧光光谱分析技术应用于井中岩心、地表土样、地下水的分析研究 ,可以判断油气的属性和油源关系 ,从而进行油气索源及有机地球化学研究。由于轻芳烃有一定的挥发性和变异性 ,样品的保真非常重要。如果解决了荧光分析的准确定量问题 ,将给准确预测气层、轻质油、中质或重质油层、烃源岩等提供强有力的依据。

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.
