摘　　要：分析了温度、油水比和乳化降粘剂R-1,R-2的用量对河南G7412井超稠油HN降粘效果的影响,利用正交实验法研究了R-1和R-2对超稠油HN的降粘效果,两种降粘剂的最佳使用条件为:温度在70℃,用量为0.9%,油水比为4∶6,R-1的降粘率可以达到99.88%;温度在90℃,用量为0.9%,油水比为7∶3,R-2的降粘率可以达到98.92%。红外光谱结果表明,超稠油HN加入R-1后降粘效果明显是由于减少杂环或胺基形成氢键的数量,从而降低了胶质与沥青质之间的缔合度。The effect of temperature, oil-water ratio and dosage of emulsifying viscosity reducer R-l, R-2 for a kind of super heavy oil HN from well G7412 in Henan on viscosity reducing influence was studied. The best application conditions of these two emulsifying viscosity reducers were as follows：temperature 70℃ ,amount of viscosity reducer R-1 0.9% and oil-water ratio 4：6 ,the viscosity reducing rate reached 99.88% ;temperature 90℃ ,amount of viscosity reducer R-2 0.9% and oil-water ratio 7：3 ,the viscosity reducing rate reached 98.92%. The conclusions of infrared spectrum showed that as the reduction of for- mation of hydrogen bonds by heterocyclic or amino, association degree of colloid and asphaltene de- creased,then viscosity of super heavy oil HN declined.
