摘　　要：探讨了无机盐溶液中阴、阳离子对聚丙烯酰胺 (PAM)溶液粘度的影响 ,确定了影响 PAM溶液粘度的主要因素是二阶阳离子 (如 Ca2 + 及 Mg2 + 离子 ) ,研究 PAM在高矿化度油田采出水中加入增粘稳定剂以保持 PAM在油田采出水中的粘度 。The effect of various cations and anions in inorganic salt solutions on the viscosity of polyacrylamide was studied. The viscosity loss of polyacrylamide could be mainly ascribed to the presence of divalent cations such as Ca 2+ and Mg 2+ . The viscosity of polyacrylamide in the highly mineralized oilfield outflow water was maintained with the addition of stabilizing agents, and the result was satisfying.
