采用三维荧光光谱法进行塔里木盆地原油──源岩的对比研究

The comparison between the oil and the oil source rock in Tarim basin using three dimensional fluorescence

本文采用三维荧光光谱法研究塔里木盆地的原油──源岩对比．三维荧光光谱图、等值线指纹图和聚类分析法可以判别原油的来源．结果显示塔中、英买力奥陶系和东河塘地区的原油来源于塔中和英买力地区奥陶系生油岩，而轮南地区的原油具有多油源性．

he comparison between the oil and the oil source rock in Tarim basim was made withthree dimensional fluorescence. Three dimensional fluorescence spectra, contour chart andcluster anslysis were used to determine the source of oil. The results show that the ordovicanoil in central Tarim basin and Yinmaili and the oil in Donghetang originated from the ordovican oil source rock in central Tarim basin and Yinmaili. But the origin of oil in Lunnan is verycomplex.and it may be originated from different oil source rock.
