摘 要:针对聚丙烯酰胺耐温耐盐性能差,在高温卤水管道中减阻性能大幅降低的特点,以聚丙烯酰胺为主要原料,对其进行磺甲基化,引进耐温耐盐的磺甲基。以改性产物在卤水中的减阻率为考核指标,通过正交试验对合成条件进行了优化,得到了最佳合成条件。结果表明,将合成的SPAM按20 mg/kg的比例加入到温度20℃、氯化钠含量150 g/L的模拟卤水中,在Re为32 000的条件下,卤水管道的减阻率为40%,80℃时减阻率为27%,减阻效果明显好于聚丙烯酰胺。As the temperature and salt resistance of polyacrylamide(PAM) is poor, the drag reduction performance in brine pipeline reduced greatly at high temperature. To sulfonated methyla- tion of PAM, the introduction of temperature and salt resistant sulfonated methyl can improve. Based on the drag reduction rate of modified products in brine, assessment index of synthesis condi- tion was optimized through the orthogonal experiment. The optimum synthesis condition was ob- tained. The results showed that the drag reduction rate of the SPAM was 40% under the condition of 150 g/L sodium chloride content and Re of 32 000 with the amount of drag reduction agent of 20 mg/kg at 20 ℃. When the temperature was 80 ℃, the drag reduction was 27%, which showed that the drag reduction effect was much better than that of PAM.
