摘要: 1H和13C NMR技术对未经处理的原油进行了直接测定.原油样品采自新疆、胜利及华北等油田,在分析原油的NMK谱线并计算原油各种平均结构多数的基础上,提出了可作为原油指纹的6个乡量:fa,Hm,Cz,mA,mN,mp.这些参数反映了不同类型原油的特点,可用于对原油进行快速和粗略的评价。

Abstract: Sonme samples of crude oil without preliminary treatment from Xinjiang,Shengli and Huabei oilfield have been determined diredly by13C and 1H NMR spectrometry.From the resulting spectra,a series of average structural parameters has been derived.On the basis of those results,parameters fa,Hm,Cz,mA,mN,mP have been proposed as the fingerprints of crude oil,which allow various oils to be characterized.The method can provide a quick but rough guide to the cvaluation and dassification of the crude oil.
