This study evaluated and screened the indoor performance of quaternary ammonium salt imidazoline type corrosion inhibitors X and Y currently used in Well Yan A of Jingbian Gas Field by hanging plate weight loss method and electrochemical method.The research results showed that the corrosion inhibition order of inhibitor X on three types of steel was 110S＞80S＞P1 10,and the highest corrosion inhibition rate was achieved when the inhibitor dosage was 150mg/L.The corrosion inhibition order of corrosion inhibitor Y on three types of steel is P110＞110S＞80S.The highest corrosion inhibition rate is achieved at a dosage of 120mg/L,and the performance of corrosion inhibitor Y is better than that of corrosion inhibitor X.Finally,in order to further enhance the corrosion inhibition effect,the filling system of the corrosion inhibitor was improved.
