摘要: 针对充气钻井中钻具的腐蚀,研究了3.5%NaCl溶液中氧含量对G105钢腐蚀行为的影响?失重实验结果表明:G105钢在卤水中主要发生氧腐蚀,腐蚀速率与氧含量有关;不同充气条件下其在3.5%NaCl溶液中的腐蚀规律受温度和氧含量的影响,并与氧含量之间有线性关系?

关键词 ：充气, 氧腐蚀, G105钢, 腐蚀规律

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.

Key words： aerated fluids oxygen corrosion G105 steel corrosion law
