在含CO_2/H_2S介质中油气田用钢的腐蚀研究进展

Research Development of Corrosion of Steels in CO_2/H_2S -containing Media in Oil & Gas Fields

研究了CO_2和H_2S对油气田开发用钢材的腐蚀机理、分析了影响因素以及防护措施,并对研究进展情况进行综述。指出目前国内各油气田关于CO_2/H_2S的腐蚀问题,一方面对腐蚀机理的认识还不够全面与深入,另一方面其防护技术研究尚未达到系统化和实用化的程度。

The corrosion mechanisms of CO_2 and H_2S on steels in oil & gas fields development are studied,the impact factors and protection approaches are analyzed,and associated research development is reviewed.The current problems in the research activities of CO_2/H_2S corrosion in domestic oil & gas fields are that there is no comprehensive deep understanding of corrosion mechanisms and great efforts have to be made before the research & development of corrosion protection becomes systematic and commercially appl...
