摘要: 随着三次采油技术的不断发展,油井堵塞问题越来越严重。主要研究了不同浓度的二氧化氯对聚丙烯酰胺的降解作用,以及温度对其影响,并对二氧化氯降解聚丙烯酰胺的机理进行了探讨。主要测定在6 h内,随着时间的变化,不同温度及不同二氧化氯浓度下聚丙烯酰胺的黏度,以此来判定二氧化氯对聚丙烯酰胺的降解效果。结果表明:在室温下,降解2%(质量分数)的聚丙烯酰胺溶液的最佳二氧化氯质量分数为4×10-3;当二氧化氯质量分数为4×10-3时,降解2%(质量分数)的聚丙烯酰胺溶液的最佳温度为60 ℃。

Abstract: With the development of EOR technology,the problem of oil congestion is more and more serious.Degradation of polyacrylamide by different concentrations of chlorine dioxide,and the influence of temperature were mainly studied.Degradation mechanism of polyacrylamide by chlorine dioxide was also discussed.Viscosity values of polyacrylamide as the change of time in six hours,in different temperature or different chlorine dioxide concentrations were mainly determined,so as to decide the degradation effect of chlorine dioxide.Results showed the best chlorine dioxide mass fraction was 4×10-3 for polyacrylamide degradation at room temperature when its mass fraction was 2%;the best temperature of 2%(mass fraction) polyacrylamide degradation was 60 ℃ when chlorine dioxide mass fraction was 4×10-3. 
