Abstract:

The water-soluble negatively charged polyacrylamide was prepared by free radical copolymerization method. The interaction between negatively charged sulfonated polyacrylamide and triethylenetetraamine was investigated in aqueous solution and mineralized water. The results indicated that the addition of triethylene-tetraamine can efficiently influence the viscosity and rheological properties of sulfonated polyacrylamide, which provides the theoretical basis for the further application in oil displacement.

Key words: Polyacrylamide, Triethylenetetraamine, Oil displacement
