在石油天然气开采和储运过程中因半生气体CO2的存在,对油气田管线会产生严重的腐蚀和重大的经济损失。针对管线钢特定的腐蚀环境,总结了当前CO2腐蚀在反应机理上的研究,简要介绍了温度、CO2分压、pH值和流速等多种因素对管线钢在CO2环境中腐蚀的影响,综述了近年来国内外管线钢在CO2环境中的腐蚀问题研究现状及发展趋势。 Due to the existence of half-life gas CO2 during the process of oil and natural gas exploration and storage, severe corrosion and significant economic losses will occur to oil and gas pipelines. In view of the specific corrosion environment of pipeline steel, the current research on the reaction mechanism of CO2 corrosion is summarized. The effects of various factors such as temperature, CO2 partial pressure, pH value and flow rate on the corrosion of pipeline steel in CO2 environment are summarized. Research Status and Development Trend of Corrosion of Pipeline Steel in CO2 Environment at Home and Abroad in Recent Years.
