Abstract Aimed at the corrosion of G105 drill pipes in aerated drilling fluids, the impact of dissolved oxygen of 3.5% NaCI solution on the corrosion behavior of G105 steel was studied using weight loss method.The tests revealed that the corrosion of G105 steel in brine was considered as oxygen corrosion; the temperature and dissolved oxygen affected the corrosion rate of G105 steel in aerated 3.5%NaCI solution:at the same temperature,the corrosion rate increasing with the content of dissolved oxygen;at the same aerated condition,the corrosion rate increased when the temperature was elevated from 25 ℃ to 65 ℃ and reached the maximum at 65℃.The corrosion rate of the G105 steel and dissolved oxygen of 3.5%NaCI solution obeyed linear relationship.
