摘　　要：随着农村“煤改气”工程的迅速开展,对提高农村生活质量、改善大气环境发挥重要作用的同时,安全问题也日益突出,其中农村地区冬季水堵事故是其中一个较为突出的问题,对农村燃气用户以及供气企业造成巨大损失。本文介绍了北京市南部农村“煤改气”地区低压燃气管线水堵状况,通过分析水堵形成原因,针对其影响范围大、分散性强、反复发生、治理困难等特点,结合城镇燃气埋地管线水堵抢修方法,提出一种适合农村地区低压燃气管线水堵的抢修方法——压缩机排水法,并阐述了该方法的主要内容、工作流程、应用实例和效果。实践表明,该方法适用于农村地区低压燃气管线水堵事故的抢修,有效避免或减少燃气管线水堵事故的反复发生,可在农村地区水堵事故中推广应用。With the rapid development of the rural"Coal to gas"project,while playing an important role in improving the quality oflife in rural areas and improving the atmospheric environment,safety issues have also become increasingly prominent.Among them,water blockage accidents in rural areas in winter are one of the more prominent issues,Causing huge losses to rural gas users and gas supply companies.This article introduces the water blockage oflow-pressure gas pipelines in the rural"coal-to-gas"area in southern Beijing.Through analysis of the causes of water blockage,it is based on the characteristics oflarge impact,strong dispersion,repeated occurrence,and difficult governance,combined with urban gas buried The emergency repair method of pipeline water blockage,a emergency repair method suitable for water blockage oflow-pressure gas pipelines in rural areas-compressor drainage method,and the main content,work flow,application examples and effects of the method are described.Practice has shown that this method is suitable for repairing water blockage accidents in low-pressure gas pipelines in rural areas,effectively avoiding or reducing the repeated occurrence of water blockage accidents in gas pipelines,and can be popularized and applied in water blockage accidents in rural areas.
