Mechanism of Protective Action of Inhibitors Based on Quaternary Ammonium Compounds
Keyword(s):
Currently, inhibitory protection is one of the most effective and common methods of protecting the inner surface of oil field equipment from corrosion. The work explores the mechanism of protective action of new inhibitors based on quaternary ammonium compounds and assesses feasibility of their practical application in oil fields of OJSC Surgutneftegas. Studies were conducted on samples made of pipe steels A 568M, A 516-55 and 13CrV (rus 13ХФА) in a model produced water solution. Three corrosion inhibitors were tested. Parameters of the mechanism of protective action of reagents were determined by potentiodynamic analysis.
