Research progress on factors affecting oxygen corrosion and countermeasures in oilfield development

Abstract

Water injection, air injection, air foam injection, and in-situ combustion technology are used step by step in the later period of oilfield. Oxygen corrosion caused by different development methods has become a problem that could not be ignored. In this paper, the mechanism of oxygen corrosion, the influencing factors of oxygen corrosion and the new progress of oxygen corrosion countermeasures in recent years are systematically analyzed. Anticorrosion methods for different development modes are put forward. The direction of further research on oxygen corrosion in oilfield development is proposed: Prediction and control of corrosion in oxygen environment need to be further studied to better guide corrosion protection in high temperature injection and production of oil and gas wells. The research of anticorrosive coating materials and corrosion inhibitor technology needs to be further developed in the direction of safety and environment-friendly.
