摘要： 对稠油主要族组 分的含量与粘度关系进行了定量的实验研究。结果表明,饱和烃、芳烃、中性非烃、酸性非烃、胶质和沥青质的质量分数分别与稠油的粘度呈指数函数关系。稠油的粘度随饱和烃和芳烃质量分数的增加而呈指数函数关系降低,随中性非烃、酸性非烃、胶质和沥青质质量分数的增加而呈指数函数关系升高,对稠油粘度影响重要程度的顺序为:胶质和沥青质>酸性非烃>中性非烃。其中,胶质和沥青质的质量分数是影响稠油粘度的最主要因素,这与其它实验研究结果是一致的。降低稠油中的中性非烃、酸性非烃、胶质和沥青质质量分数,将有效降低稠油的粘度。

Abstract: The quantitative experiments for study of relationship between heavy oil composition and its viscosity are made. The result show sthat the relationship of exponential function occurs between percentage content of saturated hydrocarbon, aromatic hydrocarbon, neutral non-hydrocarbon, acidic non-hydrocarbon, colloid and bitumencarb in heavy oil and its viscosity. Among them, the viscosity of heavy oil decreases.with the increase of contents of saturated hydrocarbon and aromatic hydrocarbon, and increases with the increase of contents of neutral non-hydrocarbon, acidic non-hydrocarbon, colloid and bitumencarb in the form of exponential function. The degree of the influence on the viscosi-ty is as follows: colloid and bitumencarb>acidic non-hydrocarbon>neutral non-hydrocarbon, the former is the most important factor to affect the viscosity of heavy oil or absolutely contributes toit. This is coincident with the results from other experiments. Hence, to decrease the conten of neutral and acieic non-hydrocarbons collaid and bitu mencarb will effeetively decre ase the viscosity of heavy oil.
