油气管道CO2/H2 S腐蚀及防护技术研究进展
Research Progress of CO2/H2 S Corrosion in Oil and Gas Pipelines and the Protection Techniques
摘要
Abstract
ABSTRACT:CO2 and H2 S are the major corrosion media in oil and gas pipeline, often existing in both crude oil and natural gas. Their presence is one of the main causes for internal corrosion in oil and gas pipelines, and even leads to pipeline failure, perfora-tions, leaks and cracks. It′s a serious threat to the safe operation of the pipeline network and normal production. So pipeline corro-sion problems caused by CO2 and H2 S have become a hot issue of current research. For the growing oil and gas pipeline corrosion problems caused by CO2 and H2 S, the corrosion behaviors of oil and gas pipelines in CO2 alone, H2 S alone and the co-existence of CO2 and H2 S system were systematically compared in this paper. The law and mechanism of pipeline corrosion behavior in these three corrosion systems were obtained. And the protection techniques against oil and gas pipeline corrosion were listed, such as cor-rosion inhibitors, corrosion resistant pipes, electrochemical corrosion technology and pipe coating corrosion protection technology, and the characteristics, advantages and limitations in practical use of these protective measures were analyzed. Furthermore, the outlook about further research directions in CO2 and H2 S co-existence system as well as more economical and effective anti-corrosion measures was prospected.关键词
