Abstract: The CO₂ corrosion is an important issue which has troubled oil and gas field development. There has a variety of anti-corrosion measures in view of the serious CO₂ corrosion problems. And the application of corrosion inhibitors for corrosion protection has been recognized as a cost-effective measure. This paper analyzed the importance and feasibility of the corrosion prediction and monitoring, introduced several commonly used anticorrosion measures, and the focus of which is on the feasibility of corrosion inhibitors for corrosion protection.
