摘　　要：海上油气田水下设施投入生产后,各类型钢结构水下设施除涂层保护外,会采用牺牲阳极、外加电流或两者相结合的不同阴极保护技术的防腐措施,这些防腐系统的状态将会影响水下设施的安全和使用寿命。通过阴极保护检测和评估,能及时评估水下设施的腐蚀状态,及早发现异常并尽快采取补救措施,使设施长期安全运行。本文主要对阴极保护技术的基本原理、阴极保护的电位测量技术进行阐述,并对阴极保护在各类型水下设施的应用、电位测量技术的对比和应用情况进行分析,着重对辉固阴极保护监测系统(Fugro Cathodic Protection Monitoring System,FCPMS)的组成和应用成果进行介绍,以及对未来阴极保护技术和电位测量技术的使用趋势进行论述。After the underwater facilities of offshore oil and gas fields are put into production,in addition to coating protection,different cathodic protection technologies,such as sacrificial anode,ICCP(Impressed Cur-rent Cathodic Protection)or a combination of them will be adopted for various types of steel structure under-water facilities.The state of these anti-corrosion systems will affect the safety and service life of the underwa-ter facilities.Through cathodic protection detection and assessment,the corrosion status of underwater facili-ties can be evaluated in time,the anomalies can be found early and remedial measures can be taken as soon as possible to ensure the long-term safe operation of the facilities.This article mainly expounds the basic princi-ple of cathodic protection technology and the potential measurement technology of cathodic protection.The application of cathodic protection in various types of underwater facilities,the comparison and application of potential measurement technology are analyzed.The composition and application results of the Fugro Cathod-ic Protection Monitoring System(FCPMS)are mainly introduced,and the application trends of cathodic pro-tection technology and potential measurement technology in the future are discussed.
