Abstract

Abstract: The mechanism of HPAM oxidative degradation and the chemical methods of retarding such oxidative degradation are analyzed. The effect of dissolved oxygen on the stability of S₇₂₅polymer, as related to the polymer flooding performance in Henan oilfield, is studied. Results show that the viscosity of
S₇₂₅ solution prepared with clean water or production water drops rapidly in the presence of oxygen at 65℃. Good viscosity stability can be gained by combination of several additives.

Key words: degradation, polymer, stability, viscosity
