将委内瑞拉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委内瑞拉稠油及其组分的基本性质及结构参数，对稠油及其组分的平均结构参数进行分析计算。结果表明，委内瑞拉稠油数均相对分子质量的大小顺序是：沥青质＞胶质＞芳香分＞饱和分，沥青质的数均相对分子质量要远远大于其他3个组分的数均相对分子质量。委内瑞拉稠油的结构参数CT 、HT 、CA 、RA 、RT 、RN 、CN 、C ．I ．大小顺序均为：沥青质＞胶质＞芳香分＞饱和分。委内瑞拉稠油的饱和分红外谱图在2800～3100 cm -1和1350～1390 cm -1出现强吸收峰，属于甲基和亚甲基的特征峰。羟基、羰基等基团的存在使委内瑞拉稠油胶质与沥青质分子之间及沥青质本身分子形成氢键。

Heavy oils of Venezuela heavy oil was separated into four fractions which were saturate ,aromatic ,resin and n-C7 insoluble asphaltene .Average structural parameters of heavy oil and its fractions were analyzed and computed .The results show that 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 .The infrared spectrum of Venezuela heavy oil'saturate shows that there were two strong absorption peaks between 2 800~3 100 cm -1 and 1 350~1 390 cm -1 ,which were methyl and methylene .Groups of hydroxyl and carbonyl lead to hydrogen bond between resin and asphaltene .
