摘　　要：降低聚丙烯酰胺的黏度对于研究聚合物驱采油及其采出水的处理、煤气化灰渣的循环利用等有重大意义。本文考察了pH值、氧化物及矿化度对阳离子聚丙烯酰胺溶液黏度的影响,实验结果表明当pH值达到8.5时,阳离子聚丙烯酰胺溶液黏度急剧下降;当NaClO加入浓度达到60 mg/L时就能有效的分解聚丙烯酰胺;当NaCl加入量在250 mg/L时就能使聚丙烯酰胺溶液的黏度降低一半。Significant decrease the viscosity of polymerization is very important in polymer flooding, sewage water treatment and the gasification ash recycling. In this paper, the effects of pH value, oxide and the effect of salinity on the viscosity of cationic polymerization solution were investigated. The experimental results showed that the viscosity of cationic polymerization solution decreased sharply when the pH reached 8. 5. It also showed that the cationic polymerization decomposed when NaCIO concentration reached 60 mg/L; And the viscosity of polymer solution was reduced by half when the addition amount of NaCl of 250 mg/L.
