综述了金属阳离子对部分水解聚丙烯酰胺溶液(HPAM)黏度影响的研究现状,解释了不同价态金属阳离子对HPAM的降黏作用机理,介绍了采油污水处理中金属离子的脱除技术。对目前金属离子与HPAM作用研究中存在的问题以及未来的发展方向进行了总结。
The effect of metal cations on the viscosity of partially hydrolyzed polyacrylamide solution ( HPAM ) are reviewed, the viscosity reduction of HPAM caused by metal cations with different valences are explained, and the technology of metal cations removal applied in oilfield produced water treatment are introduced. The present problems and the development prospect of the interaction be- tween HPAM and metal cations are put forward.
