10月1日21时33分，华北油田山西煤层气勘探开发分公司成庄作业区生产运行中心主任刘方成的值班电话突然响起，一条急促的报修消息打破深夜宁静：“樊71平10L井组突发停电故障，急需抢修。”

At 21:33 on October 1st, the duty phone of Liu Fangcheng, the production and operation center director of Chengzhuang Operation Area of Shanxi Coalbed Methane Exploration and Development Branch of North China Oilfield, suddenly rang. A urgent repair message broke the silence of the night: "There is a power outage fault in Well Group 71 Ping 10L of the well, and immediate repair is urgently needed."

樊71平10L井组是成庄作业区高产重点井。井场搭载了光伏与市电双电源系统，并配套了水力管式泵、电潜泵2套核心排采设备。电力与设备控制系统联动，故障隐蔽性极强、排查难度大。

The Fan 71-10L well group is a high-yield key well in Chengzhuang operation area. The well site is equipped with a dual power supply system of photovoltaic and grid power, and is also equipped with two sets of core production equipment such as hydraulic tubular pumps and electric submersible pumps. The power and equipment control systems are linked, making the fault detection extremely difficult and complex.

彼时正值国庆用气高峰期，如果井组长时间停机，会打乱区域供气的节奏。接到报修后，刘方成立即放下手头的值班台账，第一时间联系维修班李荣、水平井班连小伟，并按照国庆应急值守预案，迅速集结，奔赴井场。

At that time, it was the peak period for national holiday gas usage. If the well group was to be shut down for a long time, it would disrupt the regional gas supply rhythm. After receiving the repair report, Liu Fang immediately put down the duty log in his hands and immediately contacted maintenance team member Li Rong and horizontal well team member Lian Xiaowei. According to the emergency duty plan for the national holiday, he quickly gathered his team and rushed to the well site.

在奔赴途中，刘方成结合井组运行台账，细致梳理光伏切换、市电回路等潜在失效点位。连小伟复盘了2套排采设备的控制系统联动逻辑。二人协同推演，提前敲定“分段验电、锁定控制箱、带负荷试运”的标准化抢修流程。

During the journey, Liu Fangcheng, in combination with the operation records of the well group, meticulously examined potential failure points such as the switching of photovoltaic systems and the mains power circuits. Liang Xiaowei then reviewed the control system interlocking logic of two sets of production and extraction equipment. The two worked together to develop a standardized emergency repair process of "partial voltage testing, locking the control box, and load test operation" in advance.

抵达井场后，3人迅速分工，即刻开展全方位抢修作业。李荣专注供电系统排查，对供电回路、配电柜、线路绝缘性能开展拉网式核查，逐段核验、逐点检测。连小伟全面检查泵体运行状态与控制系统，精准核对启停参数、核查信号反馈情况。刘方成实时对接作业区值班室与备件库，高效衔接各抢修环节。

After arriving at the well site, the three individuals quickly divided their tasks and immediately began comprehensive emergency repair work. Li Rong focused on inspecting the power supply system, conducting a comprehensive check of the power supply circuits, distribution cabinets, and insulation performance of the lines, verifying each section and testing each point. Lian Xiaowei comprehensively inspected the operation status of the pump body and the control system, precisely checking the start and stop parameters and verifying the signal feedback. Liu Fangcheng promptly connected with the duty room of the operation area and the spare parts warehouse, efficiently coordinating each emergency repair step.

经过逐层排查，连小伟成功锁定故障根源：控制箱出线继电器烧毁，引发供电回路短路，是导致设备全停、产气中断的核心原因。

After a thorough investigation layer by layer, Xiao Wei was able to accurately identify the root cause of the fault: The output relay of the control box had burned out, causing a short circuit in the power supply circuit, which was the primary reason for the complete shutdown of the equipment and the interruption of gas production.

李荣迅速调取备用继电器，严格遵循停送电安全流程，熟练地完成了配件更换、接线复位与回路调试等工作。刘方成则同步复核双电源切换逻辑。

Li Rong quickly retrieved the backup relay and strictly followed the power-off and power-on safety procedures. He skillfully completed tasks such as component replacement, circuit reset, and loop debugging. Liu Fangcheng simultaneously reviewed the dual power supply switching logic.

随后，他们依次完成设备全面复检、系统调试、空载及带负荷试运行等工序，确认井场的供电恢复正常，2套排采设备平稳重启，樊71平10L井组也恢复正常产气。

Subsequently, they successively completed the comprehensive re-inspection of the equipment, system debugging, no-load and load-carrying trial runs, etc. They confirmed that the power supply at the well site had returned to normal, the two sets of production and extraction equipment had restarted smoothly, and the production gas output of the Fan 71 Ping 10L well group had also returned to normal.

抢修结束时已是次日凌晨，3人满身尘土、双手油污。他们望着监控屏稳步回升的气量数据、听着设备平稳的运转声，终于露出了开心的笑容。

By the time the emergency repair was completed, it was already the early hours of the next day. The three workers were covered in dust and their hands were smeared with grease. Looking at the steadily rising gas volume data on the monitoring screen and listening to the smooth operation sounds of the equipment, they finally smiled happily.
