摘要:: 随着自然条件恶劣地区油田的开发以及密集管网的日渐增多，阴极保护所需的电源、土壤电阻率高给阳极安装带来的困难、荒芜人烟地区给检测带来的不便、管网密集地区的干扰等问题就成为实施阴极保护必须解决的技术问题。文章从电源、带状牺牲阳极、辅助阳极、阳极地床减阻剂、检测方法等方面介绍了阴极保护技术的进展及应用现状。
As increase of development in pipeline system densely at badly natural circumstances areas, the needs of power source for catholic protection, the difficulty for installing anodes due to higher electric resistance of soil, the inconvenience for measuring due to desolation conditions and disturbance at the pipeline system dense areas, all these problems should be solved in applying catholic protection. The paper introduces advances in catholic protection techniques and actual applications in power source, such as strip sacrifice anode, assistant anode, anode's bed resistance reducer and measuring methods etc.
