游梁式抽油机生产故障自动监测系统设计

为了实时准确监测游梁式抽油机的生产运行状态,及时对停井及停电等故障进行排查和处理,研发了一套适用于油田生产现场的油井生产故障自动监测系统。系统采用接近开关检测曲柄销的运动状态,采用ACDC模块检测抽油机的供电状态,应用GSM网络将报警信息远传至上位机系统,通过页面开发和网络发布,实现了油井生产运行状态的在线实时监测。现场应用表面,系统停电报警响应时间小于20 s,停井报警响应时间小于60 s,且无误报漏报情况发生,满足现场实时性与准确性要求。

Beam-pumping unit production breakdown automatic monitoring system design

In order to monitor the beam-pumping unit production status accurately and process the breakdown or power failure in time, a production breakdown monitoring system for the beam-pumping unit is researched and developed. The proximity switch is adopted to detect the state of motion of the crank pin. The ACDC module is used to detect the state of power supply. The alarm information is transmitted to the upper computer by GSM network. The pages are developed and published. The online real-time monitoring of running status of the beam-pumping unit is realized. The application result shows that the response time of power failure is less than 20s, the response time of breakdown is less than 60s, and the system meets the real-time and accuracy requirements.
