摘　　要：本文以AM,AA为骨架单体,AMPS,DMDAAC为功能强化单体,过硫酸铵为引发剂,采取水溶液聚合法合成了四元共聚物堵水剂AAPD,用正交优选出选择性堵水剂的最佳配方是:AM:AA:AMPS:DMDAAC=11:5:1:1,引发剂浓度0.25%,反应温度55℃,单体浓度25%,pH值为7。用红外谱法对其进行了表征,并评价了它的抗温耐盐性、封堵率以及选择性,实验结果证明该堵水剂具有好的耐温抗盐性和有较好的选择性。In this paper polymerization quaternary copolymer(AAPD) is composed of AM and AA as the armature monomer, monomer AMPS and DMDAAC for strengthening the func tion and ammonium persulphate as initiator aqueous with aqueous solution .And orthogonal optimization of selective water shutoff of the best recipe is: AM:AA:AMPS:DMDAAC=11:5:1:1, 0.25% initiator concentration, temperature of 55 ° c, 25%,pH monomer concentration value is 7. Use infrared spectroscopy on the characterization. Rated temperature and salt resistance, blocking resistance rates, and selective, the experiment proved that the water shutof has good heat resistance and salt resistance and good selectivity.
