石油采掘中酸化作业的防腐蚀,主要依靠向酸液中投入缓蚀剂。近代高温酸化缓蚀剂的发展,是缓蚀剂的一个重要分支。石油钻井逐渐向深井方向发展。井的深度增加,由于地热的缘故,井温也就随之增加,这就给酸化作业的防腐蚀工作带来了困难。因为温度升高,酸液急剧地腐蚀油管,如果不使用相应的高温缓蚀剂,井底钢制设备将会受到严重破坏。文献曾对一口生产 Acid extraction in oil extraction anti-corrosion, mainly rely on the acid into the corrosion inhibitor. The development of modern high temperature acidification corrosion inhibitor is an important branch of corrosion inhibitor. Oil drilling gradually to the direction of deep well. The depth of the well increases and the temperature of the well increases as a result of geothermal heat, which poses difficulties for the anti-corrosion work of the acidification operation. Because of the temperature rise, the acid corrodes the tubing drastically, and the bottom hole steel equipment will be severely damaged if the corresponding high temperature corrosion inhibitor is not used. The literature had a production
