采用灰色关联熵分析法研究了胜利油田稠油黏度与其极性四组分含量和极性组分偶极矩的关联。同时通过改变实验油样乳状液的含水率及温度，探究了稠油组成性质与其乳状液反相点的关联。结果表明：稠油极性四组分含量与其黏度关联度的顺序是：沥青质＞胶质＞芳香分＞饱和分；稠油极性组分偶极矩与其黏度的关联度顺序是：沥青质＞胶质＞芳香分。随着稠油胶质、沥青质含量的增大，油水界面张力的降低、油滴Zeta电位绝对值的增大，乳状液含水率的反相点及温度的反相点逐渐升高。

The correlation between the contents and properties of polar fractions and the vis-cosity of heavy oil were studied by gray correlation entropy method .By changing volume fraction of water and temperature of the emulsions of heavy oil ,the relation between the composition property of heavy oil and the reverse phase point were also researched .The result showed that the order of correlation degree between the polar fractions and the viscosity of heavy oil was :as-phaltene>resin>aromatic>saturate;and the order of correlation degree between the mean dipo-lemoments of polar fractions and the viscosity of heavy oil was :asphaltene>resin>aromatic .In addition ,as the increase of the contents of the resin and asphaltene ,the decrease of the interfacial tension of oil-water ,and the increase of Zeta absolute value of oil drops ,the volume fraction of water and temperature at the reverse phase point of emulsion gradually raised .
