【摘要】 根据地下深水井的结构特点，设计了特制的垫圈式环状和齿轮环状辅助阳极；通过中型动态模拟试验，为确定工程设计参数提供了可靠的依据。深水井工程施工和系统运行结果表明，深水井扬水管及井口管线外加电流阴极保护设计合理、施工简单、维护方便，技术指标达到了设计要求。更多还原

【Abstract】 Based on the configuration features of decp water wells,ringlike and gear-ringlike auxiliary anode are designed.By making simulated dynamic tests,reliable bases for determining the parameters of engineering design are presented.By the constructlonal and opertional results of deep water wells,it is shown that the designs of cathodic protection for outlet pipes and well head plpelines of deep water wells are reasonable,easy to install and maintain,and its norm meets the design requirements.更多还原
