Selection of a corrosion inhibitor for pipeline protection

The article presents the results of a study of the effectiveness of various corrosion inhibitors for the protection of oil pipelines. A comparative analysis of three types of inhibitors in conditions of high mineralization of reservoir water has been carried out. It was found that inhibitor A demonstrates the best protective properties with a minimum corrosion rate of 0.082 mm per year at a dosage of 20 milligrams per liter. Pilot field tests have confirmed the effectiveness of the selected inhibitor with an increase in dosage to 25 milligrams per liter.
