中国石油网消息：一套成本160元的装置，预计年可创效超100万元。6月5日，笔者从大港油田采油三厂获悉，这个厂作业五区采注运维一组党员攻关团队扎根一线，凭借“抽油机井杆卡时自动停机保护装置”，实现了小投入大效益。

China Petroleum News: A device costing 160 yuan is expected to generate over 1 million yuan in annual benefits. On June 5th, the author learned from the Third Oil Production Plant of Dagang Oilfield that the Party member research team of the Operation and Maintenance Group of the Fifth Zone of this plant has been working on the front line. By relying on the "automatic shutdown protection device for stuck rods in pumping wells", they have achieved significant benefits with a small investment.

该厂现有油井1200余口，游梁式抽油机的占比超8%。受原油“三高”特性影响，杆打架、杆卡、管道堵塞等故障频发，不仅造成生产成本浪费，还大幅增加了一线运维工作量，影响油井生产时效。

This oilfield currently has over 1,200 oil wells, with the proportion of beam pumping units exceeding 8%. Due to the "three-high" characteristics of crude oil, problems such as rod jamming, rod entrapment, and pipeline blockage occur frequently. This not only leads to waste of production costs but also significantly increases the workload of on-site operation and maintenance, thereby affecting the production efficiency of the oil wells.

为此，以技能专家刘永保为代表的攻关团队扎根生产现场，精准摸排生产痛点，逐一破解无触发装置、缺联动组件、无自动停机系统三大难题，研究出“抽油机井杆卡时自动停机保护装置”。

To this end, the breakthrough team led by skilled expert Liu Yongbao, who was stationed at the production site, meticulously identified the production bottlenecks, and successfully solved the three major problems of the absence of triggering devices, the lack of interlocking components, and the absence of an automatic shutdown system. They then developed the "automatic shutdown protection device for when the sucker rod of the pumping well gets stuck".

当出现泵卡等异常情况时，该装置能通过顶起扶正器，触发并上传信号，联动控制电路自动停机，实现全程无人干预的自动保护。

When abnormal situations such as pump jamming occur, this device can lift the centering device, trigger and upload signals, and联动 control the circuit to automatically shut down， achieving full-process automatic protection without human intervention.

该装置自主制作成本仅160元，落地后效果立竿见影。“以五区采注运维一组官12-33井为例，以前光是一次抽油杆磕碰故障，就得花费1.6万元的维修费；装上这套设备后，片区里5口同类问题的井，一年就能省下9万元。要是在全厂推广使用，一年光维修费、传感器换新这些开销，最少能省下100多万元。”刘永保介绍说。

The cost of independently manufacturing this device is only 160 yuan. Its effect is immediate upon implementation. "Take the operation and maintenance group of Zone 5's Well 12-33 as an example. Previously, just one incident of a sucker rod collision failure would cost 16,000 yuan for repairs; after installing this equipment, the 5 similar problem wells in the area can save 90,000 yuan a year. If this equipment is promoted throughout the factory, the expenses for maintenance and sensor replacements alone could save at least 1.06 million yuan a year." Liu Yongbao explained.
