| 中文摘要: |
| CO2和H2S是油气管道中主要的腐蚀介质，两者往往同时存在于原油和天然气之中，它们的存在会造成油气输送管道内腐蚀发生的主要原因之一，甚至会导致管道失效、穿孔、泄漏、开裂等现象，严重的威胁了管网的安全运行及正常生产。因此CO2和H2S引起的管道腐蚀问题，已成为当前研究的热点问题。针对油气管道日益严重的CO2和H2S腐蚀问题，综述了CO2单独存在、H2S单独存在以及CO2和H2S共同存在三种体系中油气管道的腐蚀过程，得出了在这三种腐蚀体系下油气管道出现的主要腐蚀行为规律以及腐蚀机理。阐述了CO2和H2S共同存在体系下，缓蚀剂、耐蚀性管材、电化学防腐技术、管道内涂层技术等先进的油气管道腐蚀防护技术，并剖析了这些防护措施各自的特点及在实际工程使用中的优势和局限性。最后，展望了CO2和H2S共存体系的进一步研究方向以及更经济、更有效的防腐措施发展前景。 |
| 英文摘要: |
| CO2 and H2S are the major corrosion mediums in oil and gas pipeline currently, often exist in both crude oil and natural gas. Their presence is one of the main reasons that causes internal corrosion in oil and gas pipelines, and even lead to pipeline failure, perforations, leaks and cracks. It’s a serious threat to the safe operation of the pipeline network and normal production. So pipeline corrosion problems caused by CO2 and H2S, has become a hot issue of current research. For the growing oil and gas pipeline corrosion problems caused by CO2 and H2S, the corrosion behavior of oil and gas pipelines in CO2 alone, H2S alone and the co-presence of CO2 and H2S system was systematically compared in this paper. The regularity and mechanism of pipeline corrosion behavior in these three corrosion systems was obtained. And the technology was listed, such as corrosion inhibitor, resisting corrosion pipe, electrochemical corrosion technology and pipe coating corrosion protection technology and other advanced technology. And analyzed these protective measures their own characteristics, advantages and limitations in practical use, prospected the outlook about further research directions in CO2 and H2S co-existence system as well as more economical and effective anti-corrosion measures. |
