Influence of Oxygen Concentration on the Corrosion Properties of Polymer Flooding Injection Water

Indoor dynamic simulation tests and electrochemical tests were peformed under the conditions of the different oxygen concentrations of polymer injection water. The corrosion characteristics were analyzed and predicted by the simulation test data, a grey GM (1, 1) model , data analysis software Origin 8.0 nonlinear regression model, and electrochemical test. The results show that when oxygen concentration increased to a certain extent, the electrochemical corrosion was weakened.
