摘　　要：依据溶度参数理论,通过模拟软件和实测方法对部分醇和醇醚进行筛选,得出合适的悬浮型减阻剂主悬浮介质;根据影响悬浮型减阻剂稳定的因素,对其存放稳定性和耐热性进行考察,得出合适的密度调节剂、乳化剂和增稠剂。由此确定悬浮型减阻剂的组成主要包括戊醇、乙二醇甲醚、Span80、Tween60、乙撑双硬脂酰胺、经包覆的高聚物颗粒等。对制得的悬浮型减阻剂的表观黏度、耐高低温性能及减阻性能等进行测定和评价,认为高聚物颗粒粒径和高聚物含量是影响其表观黏度的主要因素,减阻率随悬浮型减阻剂加入量的增大而增加,至最大值后变化趋于平缓。An alcohol-based suspending drag reducer was studied and developed. Based on the theory of solubility parameter, a suitable suspending medium was selected from alcohols and alcohol ethers by simulation software and real measurements. The kinds of density regulator, emulsifier and thickener were determined based on the examination of factors affecting storage stability and heat resistance of the suspending drag reducer. It is suggested that pentanol, 2-methoxyethanol, span80, tween60, EBS and coating agent for polymer particles are the main components of the drag reducer suspension. The apparent viscosity, high/low temperature resistance and drug reduction rate of the suspension prepared were then evaluated. It is found that the polymer particle size and polymer content in suspending drag reducer are the main factors which affect the apparent viscosity of the suspension. The drug reduction rate increases with increasing dosage of the drag reducer suspension, and then tends to flatten when drug reduction rate reaches to the maximum.
