Abstract A new natural gas drag reduction agent 3-alkyl-4-amino-5-mercapto-triazole (AAMT) was synthesized. The drag reduction efficiency of AAMT was tested on the drag reduction test loop. The film-forming property of AAMT was studied by electrochemical characterization and SEM. The results show that AAMT adsorbs on the iron surface and smooth membrane is formed. The roughness of the gas pipeline is significantly improved. Under the condition of 4g/L AAMT and 1.5h, the maximum drag reduction efficiency is 10.03%.
