Evaluation Study on Corrosion Inhibitor and Tube/Rod Material Compatibility in CO2 Injection-Production Wells
Year: 2025
Type: article
Abstract: This paper evaluates the corrosion resistance performance of different corrosion inhibitors and tube/rod materials in the injection-production well environment of Carbon Capture, Utilization and Storage (CCUS) projects. Through laboratory corrosion tests, the inhibition effects of various corrosion inhibitors and their adaptability under different working conditions were analyzed. Results show that under extreme corrosive environments, conventional corrosion inhibitors have deficiencies in protecting standard tube/rod materials. The corrosion rates of conventional tube/rod materials are generally high and comparable. As temperature and CO2 content (partial pressure) increase, there is a trend of increasing corrosion rates. Different materials show significant variations in corrosion resistance performance in CO2-containing media. This paper provides scientific basis for the selection of corrosion inhibitors and tubing materials in CCUS projects.
