| 摘 要： | 以塔里木稠油1、塔里木稠油2、塔里木稠油3为原料,将3种稠油进行四组分的分离。通过元素分析、核磁共振等分析方法研究了3种稠油及其组分的基本性质,对稠油及其组分的平均结构参数进行分析计算。结果表明,相同条件下,稠油黏度大小、残炭值和沥青质含量从大到小顺序均为:塔里木稠油2、塔里木稠油1、塔里木稠油3;塔里木稠油2的芳碳率(fA)最高,塔里木稠油3及塔里木稠油1的芳碳率很接近。3种稠油的缩合指数(C.I.)差别不大。对同一种稠油,数均相对分子质量,结构参数CT、HT、fA、CA、RA、RT、RN、CN、C.I.从大到小顺序均为:沥青质、胶质、芳香分、饱和分。

| Abstract: | Heavy oils of Tarim LG-1, Tarim LG-2 and Tarim LG-3 were separated into four sub-fractions which are saturate, aromatic, resin and n-C7 asphaltene. Average structural parameters of heavy oil and their fractions were analyzed and computed. The results show that in the same condition, the viscosity size, carbon residue value and asphaltene content in order for all the size is Tarim LG-3, Tarim LG-1, Tarim LG-2. Aromatic carbon rate （fA） is the highest in Tarim LG-2, which approaching in Tarim LG-1 and Tarim LG-2. The condensation index（CI. ） of heavy oils are closely. The same trend of average molecular weight, CT, HT, fA, CA ,RA ,RT ,RN, CN, C I. has the size order which is asphaltene, resin, aromatic, saturate. |
