金属阳离子对聚丙烯酰胺溶液黏度的影响及其降黏机理研究
, PP. 43-47
Keywords: 聚丙烯酰胺,黏度,金属阳离子,降黏机理,矿化度
Abstract:
？聚丙烯酰胺(hpam)是油田常用的驱油聚合物,用油田污水配制hpam溶液易导致其黏度明显降低,影响驱油效果。依据埕东油田污水实测的各种金属阳离子含量来配制hpam溶液,测得各金属阳离子对其黏度影响由大到小的顺序为:na+>fe2+>ca2+>k+>mg2+;通过红外光谱和扫描电镜分析金属阳离子导致hpam溶液降黏的机理,na+、k+、ca2+、mg2+主要是通过与hpam链上的羧酸根阴离子静电引力相互作用,降低hpam分子表面原有的电荷密度,造成分子链卷曲,同时减弱了极性基团的溶剂化能力,释放大量的"束缚水",从而使黏度显著降低;fe2+离子主要是与水中溶解氧共同作用,引发自由基反应,导致hpam骨架水解断裂,致使黏度显著降低。
