丛式井组套管阴极保护数字化监测仪研制与应用

Development and Application of Digital Monitor for Cathodic Protection of Cluster Well Casing

丛式井组套管阴极保护数字化检测仪,主要由监测阴极保护电流和电压的仪表、直流供电电源及远程控制终端RTU模块组成,能对丛式井组套管进行阴极保护,实现数字化远程实时监控,具有运行效率高、调压安全、体积小、质量轻、不需要专门配电房和初期投入费用低等特点。2015年至2016年在长庆油田30多个丛式井组进行了现场应用,效果良好。

Digital monitor fi）r cathudic protection of cluster well and voltage, DC power supply and remote control terminal RTU casing is mainly composed of instrument fi）r monitoring current module, which uses for cathodic protection and realizing digital remote real-time monitoring. It has the advantages of high operation efficiency, safe voltage regulation, small size, light weight, no special power distribution room and low initial investment cost, etc. From 2015 to 2016, more than 30 cluster wells were applied in Changqing oilfield and achieved good results.
