To solve the high temperature、high pressure、high CO2 content problems during process of deep wells development in Changling gas field,it takes Carbon Steel with corrosion inhibitor technologies as important measures for corrosion protection.it needs to add highly effective corrosion inhibitor.As different type of corrosion inhibitor suitable for different environment,the paper do some research on the optimizing of corrosion inhibitor and laboratory performance evaluation under modeling gasfield working condition.By detection of remnant concentration to guide the adding condition of corrosion inhibitor at working-field,it can ensure that the corrosion inhibitor concentration keeping effectively to protect the string and prolong the working life for gas wells.
