- 摘要:
- 针对四川罗家寨气田高含CO2、H2S的实际情况,通过对CO2、H2S腐蚀机理的分析研究,找出CO2、H2S腐蚀特点及其腐蚀速率的影响因素,并列举了国内外CO2腐蚀事故,进一步说明CO2腐蚀产生的条件及特征。认为四川罗家寨气田,H2S腐蚀应是一重要腐蚀因素,而不是主要腐蚀因素,其主要腐蚀因素是CO2腐蚀。选用耐腐蚀合金钢材料时,应以抗CO2腐蚀为主,兼顾抗H2S腐蚀及其他腐蚀。
The Corrosion characteristics and the effective factors of corrosion rate of CO 2 and H 2 S are found through the corrosion mechanism analysis on the high contents of CO 2 and H 2 S in Luojiazhai gas field.The CO 2 corrosion accidents happened in foreign countries are illustrated to further explain the occurrence condition and characteristic of CO2 corrosion.It concludes that H 2S corrosion is an important but not dominant factor.The dominant is CO 2 corrosion.The selection of alloy steel should focus more on the anti-corrosion performance of CO 2 than that of H 2 S.2004,1(1): 10-14 收稿日期：2003-12-1分类号：TE988.2作者简介：冯星安(1944-),男,中国石油集团工程技术研究院院长,教授级高工.主持官69区块产能建设工程、高温管道直埋技术、水下不分散混凝土等重大科研项目,获部级全优工程奖1次,工程设计二等奖1项.1999年获石油集团公司"铁人科技成就"奖,2001年获天津市特等劳模称号,2003年获全国"五一"劳动奖章.通讯地址:天津市塘沽区津塘公路40号.参考文献：
