摘要

CO_2地质利用与封存（CO_2 geological utilization and storage

CGUS）是实现“碳中和”目标的重要技术手段，解决CGUS过程中的钢材腐蚀问题对于降低CGUS技术风险、实现CGUS技术规模化推广应用至关重要。综述了目前已经提出的CO_2腐蚀钢材反应机制，总结了CO_2腐蚀钢材的主要影响因素，阐明了CO_2分压、温度、矿化度及p H值、CO_2封存环境中含有杂质、流体流动等因素对钢材腐蚀行为的影响，归纳了适用于CO_2腐蚀钢材防护的主要措施。基于此，提出了CGUS环境下钢材遭受CO_2腐蚀问题的重点研究方向。主要包括：CO_2腐蚀钢材反应机制的进一步探究；各项环境因素耦合作用影响CO_2腐蚀规律和腐蚀程度的量化研究；高浓度CO_2条件下腐蚀防护技术的开发与应用。

Abstract

CO_2 geological utilization and storage(CGUS) is an important technical means to achieve the goal of “carbon neutrality”. Solving the steel corrosion problem in the process of CGUS is crucial to reduce the risk of CGUS technology and achieve the large-scale promotion and application of CGUS technology. In this paper

the proposed reaction mechanism of CO_2 corrosion of steel is reviewed

and the main factors influencing CO_2 corrosion of steels are summarized. Moreover

the effects of CO_2 partial pressure

temperature

salinity and pH value

the CGUS environment containing impurities

fluid flow and other factors on steel corrosion behavior are clarified

and the main protective measures for CO_2 corrosion of steels are summarized. On this basis

the key research directions of steel subjected to CO_2 corrosion in CGUS environment are put forward. The directions include further exploration of the reaction mechanism of CO_2 corrosion of steels

quantitative study on the coupling effect of various environmental factors on the law and degree of CO_2 corrosion

as well as the development and application of corrosion protection technologies under high CO_2 concentration conditions.
