Abstract
Aiming at the situation of high CO 2 content in Changbei gas field and serious corrosion of surface gathering pipeline,an effective corrosion inhibitor was indeed needed to ease the corrosion rate of surface gathering pipeline.Through the evaluation of corrosion inhibition efficiency and emulsifying property of the existing corrosion inhibitor,a corrosion inhibitor for high CO 2 gas fields KYC-2 was optimized.The property of KYC-2 in high pressure simulated corrosion environment was evaluated by autoclave corrosion evaluation experiment.The field test showed that KYC-2 corrosion inhibitor was selected to be used in the field test.Using the pre-film method,the filling mode of four test wells was rotation every three days filling by branch trunk continuous way.When the concentration was 25 mg/(100 m3 ),corrosion inhibition efficiency was over 90%,and processing cost was only 0.03 (RMB)yuan/(100 m3 ).This corrosion inhibitor has significantly economic and social benefits.关键词
