摘要
文中针对大港油田所采用的套管结构,从腐蚀角度对套管内管道的腐蚀情况及在对管这全线进行阴极保护情况下,套管内管这的保护情况进行了分析,得出了无论在何种情况下在管道全线进行阴极保护时套管内的管道都得不到保护的结论。文章还对目前通常采用的几种套管内管道的保护方法进行了比较,认为采用牺牲阳极(阳极带)的方法在大港油田最为有效,并列举了这一方法的计算方式。
Aimed at the casing structure used in Dagang oil field,the conditions of corrosion and protection for the pipeline in casing are analysed in the case of cathode protection for full pipoline in this article. The conclusion showes in any way it is impossible that the pipeline in casing can be protected with cathode protection for full pipeline.The way of giving up anode is more effetive in Dagang oil field after comparing some protective methods in common use and the calculating pattern of this way is listed.
