摘　　要：优化了TLC-FID分析原油族组成的条件,在优化的条件下对原油进行了分析,得到原油的TLC-FID特征指纹图谱及其SARA族组分相对百分含量,采用EXCEL2003对原油SARA族组分相对百分含量进行了相关分析,采用SPSS11.5对原油TLC-FID特征指纹图谱进行了聚类分析及主成分分析,以进行不同来源原油的鉴别。结果表明:原油TLC-FID特征指纹图谱结合相关分析、主成分分析、聚类分析,能够鉴别不同产地来源的原油,但对差异较小的原油的区分具有一定的局限性。The conditions of TLC-FID analysis for compound-grouped fractions in crude oil were optimized. The TLC-FID characteristic fingerprinting and percent of relative content of SARA（ saturated hydrocarbon, aromatic hydrocarbon, resin, asphaltine）were obtained by the optimization. The Excel2003 was used for the correlation analysis of SARA. Spssll. 5 was used for the cluster analysis and principal component analysis of TLC-FID characteristic fingerprinting. These were used for the identification of crude oil. The results showed that TLC-FID characteristic fingerprinting combined with correlation analysis, cluster analysis,principal component analysis could be used for the identification of crude oil from different origins ,but these methods were limited to the crude oil of little difference.
