氧浓度对聚驱注入水腐蚀特性的影响

摘要

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.%针对不同氧浓度下的聚合物驱注入水分别进行室内动态模拟试验和电化学试验。利用模拟试验数据，建立灰色 GM（1，1）模型与使用数据分析软件 Origin8．0非线性拟合的模型，并结合电化学试验的极化曲线分析和预测腐蚀特性的变化趋势。分析结果显示，当氧浓度增加到一定程度时，电化学腐蚀减弱。
