| Abstract: | The viscosity enhancement of PAM aqueous solution with LW\|1 type additive was studied.The effect of some varibles such as the content of the additive,ion concentration,shear strength,PAM concentration and pH value on the increase in viscosity of the solution was discussed systematically.It was shown that the viscosity could be increased by 2～3 times when the content of the additive was up to 8?mg/L.Moreover,a probable machanism of the viscosity enhancement was suggested. |
