13C NMR DEPT METHOD APPLIED TO THE STUDY OF COMPOSITIONAL CHARACTERISTICS OF CRUDE OIL
-
摘要: 用13C NMR DEPT(Distortionless Enhancement by polarization Tiansfer)无失真极化转移增强方法对四川、新疆、大庆等地的凝析油、轻质油和一般原油进行测量,确定了它们的CH、CH2、CH3的相对含量和平均链长等结构信息,探讨了它们的结构特征。Abstract: With the basis of measurements on condensates, light oils and ordinary crude oils from Sichuan, Xinjiang and Daqing etc., using the method of 13C NMR DEPT (Distortionless Enhancement by Polarization Tranfer), the compositional data of their relative contents and average chain length of CH, CH2 and CH3 are determined, in order to approach their compositional characteristics.
