摘　　要：以葡萄糖苷、丙烯醇、环氧氯丙烷和十六烷基叔胺合成功能单体,再以丙烯酰胺、2-丙烯酰胺-2-甲基丙磺酸和功能单体为原料,采用反相乳液聚合的方法制备GnR-1,并对合成的GnR-1进行红外表征,测试了该减阻剂在酸液中的增黏性能、减阻性能、缓速性能和盐水中的减阻率。结果表明,室温时减阻剂在酸液中和盐水中具有良好的减阻性能;90℃下,在15%的酸液中具有缓速性能,一定程度上减小了酸液对碳酸盐岩的溶蚀量。At first,a functional monomer is synthesized from glucoside,allyl alcohol,epichlorohydrin and hexadecyl tertiary amine.Then GnR-1,an acid liquor drag reducing agent,is prepared via inverse emulsion polymerization method by using acrylamide,2-acrylamide-2-methylpropanesulfonic acid and the functional monomer as raw materials.GnR-1 is characterized by infrared spectrum,and its viscosity-increasing performance,resistance-reducing performance,retardance performance and resistance-reducing rate in brine are tested.It is shown that at room temperature,GnR-1 has good drag reduction performance in both an acid solution and a salt solution.At 90℃,it exhibits a retardance performance in a 15%acid solution,which can reduce the corrosion of carbonate rock by acid solution to a certain extent.
