摘　　要：随着油气管道所受交流干扰越来越严重,交流干扰防护技术亟待发展和有效应用。交流干扰有3种机理:感性耦合、阻性耦合和容性耦合;交流干扰有3种危害:管道腐蚀、人员伤害、管道损坏。根据不同的危害形式给出了防护方案,指出在工程实践中可采用数值模拟技术对交流干扰防护系统进行优化,并应加强管道运行中对交流干扰的监测。建议建立完善的管道交流干扰防护准则,同时推广交流干扰数值模拟技术及监测技术,实现管道交流干扰风险的全面管控,保障油气管道长期安全运行。As oil and gas pipelines have suffered more and more serious AC interference, relevant mitigation technology should be developed and applied effectively. AC interference occurs in 3 mechanisms, i.e. inductive coupling, impedance coupling and capacitive coupling, and may lead to 3 kinds of hazards, i.e. pipeline corrosion, personal injury and pipeline damage. This paper gives different mitigation schemes depending on the forms of hazards, and points that the numerical simulation can be used in the engineering practice to optimize AC interference mitigation system and the AC interference in pipeline operation should be firmly monitored. It also suggests that AC interference mitigation rules be established and revised and the numerical simulation and monitoring technologies for AC interference be promoted, so as to realize fullscale control of AC interference and thereby ensure the long-term safe operation of oil and gas pipelines.
