Binary Corrosion Inhibitors Offer Improved Corrosion Control

摘要

An improvement has been made in anticorrosion chemicals for oilfield use. A binary corrosion inhibitor that combines an epoxy resin and an amine curing agent has been patented and field proven. The proper application of this unique combination of chemicals forms a bond with the oxide film present on downhole metal surfaces. The result is a corrosion-inhibitor barrier that is more tenacious than conventional polar-filming amines, reducing application frequency and labor costs and, even more important, downhole failures. The binary corrosion inhibitor is also an improvement over, and is more versatile than, other epoxy-amine products.
