| Abstract: | Corrosion inhibition result of corrosion inhibitor PF-I containing imidazoline is evaluated by dynamic and static weight loss methods. The function mechanism of PF-I is analysed. Tests indicate that , as an effective film inhibitor, PF-I can inhibite the corrosion of drilling tools caused by weighted salt-water mud effectively. |
