Transportation increasing method, system and equipment for natural gas pipeline and medium

The invention discloses a transportation increasing method, system and equipment for a natural gas pipeline and a medium, and relates to the technical field of pipeline transportation increasing, and the method comprises the steps that when a natural gas pipeline station receives a transportation increasing request, LNG is injected into an injection port of the natural gas pipeline, and the temperature of the injection port is collected in real time; and the temperature of the injection opening is kept within the preset temperature range, the LNG injection amount corresponding to the transportation increasing request is completed, and transportation increasing of the natural gas pipeline is completed. According to the system, LNG is used for cooling and conveying, so that comprehensive utilization of cold energy is achieved, and the purpose of increasing the pipeline conveying amount is achieved. 本发明公开了一种天然气管道的增输方法、系统、设备及介质，涉及增加管道输送量技术领域，方法包括：当天然气管道站场接受到增输请求时，向天然气管道的注入口注入LNG并实时采集所述注入口的温度；保持所述注入口的温度在预设温度范围内，并完
