原油指纹识别技术

为使毛细管色谱“指纹”特征应用于污染事故的鉴定，采用分辨效能高的毛细管色谱柱及原油指纹识别技术，对江苏油田９个不同地区和来源的原油进行了分析考察，测定了油品中正构烷烃及姥鲛烷、植烷的含量。实验进一步论证了：以正构烷烃轮廓特征和姥鲛烷、植烷特征峰面积比值相结合的原油鉴别方法不受进样和色谱条件的影响，具有一定的准确性和可靠性。

The fingerprint diagnosis technique of crude oil

To apply the “fingerprint” feature of capillary chromatogram to the identification of pollution accident,high acuity capillary chromatographic column and crude oil fingerpring technique were adopted to have analyzed and inspected crude oil from different areas and sources in Jiangsu Oilfield and the content of normal alkane,pristane and phytane in oil samples were determined.Experiment demonstrated further that the crude oil idetification method of normal alkane delineation characteristic combined with the ratio of pristane's characteristic area to phytane was not effected by enter samples and chromatogram conditions to that this method was of certain acuity and reliability.
