By evaluating the corrosion experiments of gas lift wells and gas injection wells in an oilfield offshore,the corrosion situation of gas injection wells and gas lift wells is clarified,and corrosion protection measures applicable to gas lift wells and gas injection wells under complex working conditions are formulated.The results show that the corrosion rate of Ni-W alloy plated pendant is much lower than that of 3Cr and 13Cr materials,and 13Cr tubing and Ni-W alloy plated tubing can be selected as the internal corrosion protection program for the downhole tubing column of gas lift wells and gas injection wells.
