摘　　要：在W /O乳化重油黏度变化影响因素系统的实验研究基础上 ,利用多元回归分析的方法对掺水重油在乳化过程中黏度变化的影响因素进行了具体分析 .分析结果表明 :利用机械搅拌进行乳化的掺水重油 ,其黏度的变化与温度、掺水率、搅拌速率和搅拌时间等因素有关 ;在重油掺水机械搅拌乳化过程中影响黏度变化程度最大的因素是温度 ,其次是掺水率 ,然后是搅拌时间 ,影响程度最小的是搅拌速率 .随着温度的降低和掺水率的增加黏度是逐渐增加的 ,二者对黏度的影响程度相当 (温度的影响略大于掺水率的影响 ) ;随搅拌速率的增大和搅拌时间的延长 ,掺水乳化重油的黏度也是呈增加的趋势 ,二者对黏度的影响程度也相当 (搅拌时间的影响略大于搅拌速率的影响 ) .表 5 ,参On the basis of the former systematic experimental researches, the regression multianalysis method is applied to analyze the influencing factors on the viscosity change of W/O heavy-oil in the course of emulsification in this paper. The affecting factors consist of the temperature of W/O heavy-oil, the percentage of water added in oil, the mechanical agitating velocity and the mechanical agitating time. From the results of the regression multianalysis , it is found that ,among the affecting factors, the temperature of the heavy-oil is the most important factor, the percentage of water added in oil is the second important, the mechanical agitating time is the third , and the mechanical agitating velocity is the last important. With the decreasing of the temperature and the increasing of the percentage of water added in oil, the viscosity will increase. The two factors have the relative influencing level, and the temperature is little better. The viscosity of the W/O heavy-oil will also increase as the increasing of the mechanical agitating velocity and the mechanical agitating time The mechanical agitating velocity and the mechanical agitating time also have the same influencing level , and the mechanical agitating time is little better than the mechanical agitating velocity .5tabs., 6refs.
