摘　　要：目前,我国城镇燃气管道遭受的交流干扰越来越严重,合理有效的交流排流措施对于确保燃气管道的安全运行至关重要。由于城镇地域的限制,传统的水平锌带交流排流地床在城镇燃气管网的交流缓解中受到了挑战,急需适用于城镇燃气管网的新型交流排流地床。基于此,本文提出了一种适用于城镇燃气管网的交流排流技术—深井排流技术,并通过数值模拟计算研究获得了深井地床排流效果的影响因素及其影响规律,其研究结果可为城镇燃气管网的交流排流设计提供理论支撑和数据参考。The development of urban gas, transportation and electricity deteriorates AC interference of urban gas pipeline. The effective and economic AC mitigation methods are of great value for the safety of buried gas pipeline. Due to the limited space, the traditional AC mitigation bed （zinc ribbon） suffers from challenge when it is used on urban gas pipeline. A new AC mitigation bed is badly in need. In this work, deep well AC mitigation bed is proposed and the factors that affect its AC mitigation efficiency were investigated by simulating calculation. The calculated results could be referenced by AC mitigation designs of urban gas pipelines.
