Abstract

Rheological property of the aqueous solution, which was made of branched partly hydrolyzed polyacrylamide and water from Daqing Oilfield, was studied at 45 ℃ with HAAKE rheometer. The results showed that when polymers with similar molecular weights were studied, solutions of those with more branches showed higher viscosity. Viscoelasticity of the solution of branched polyacrylamide and that of commercial samples were also measured and compared.
