油气田开发中H_2S/CO_2腐蚀研究进展

Research progress of H_2S/CO_2 corrosion in oil and gas development

首先分别探讨了CO2腐蚀和H2S腐蚀的机理及其影响因素;进而讨论了H2S/CO2共存条件下的腐蚀机理及其影响因素,分析了国内外H2S/CO2腐蚀研究的现状和趋势,提出了油井管H2S/CO2腐蚀的防护措施,探讨了高酸性油气田腐蚀研究的热点问题及发展方向.

First, the mechanisms of H2S corrosion and CO2 corrosion and the influencing factors of them are discussed, and then the corrosion mechanism under the condition of H2S and CO2 coexistence and its influencing factors are discussed. The present situation and development trend of the study on H2S/CO2 corrosion at home and abroad are analyzed, and the protection measures to the H2S/CO2 corrosion of oil-well tubular goods are presented. The concerned problems and the development tend about corrosion research of high-sour oil and gas fields are also discussed.
