外输泵机组在线监测故障智能诊断系统研究应用

Research and Application of On-line Monitoring Fault Intelligent Diagnosis System for External Transmission Pump Unit

针对油田外输泵机组实际运行中存在的问题,研制了外输泵机组在线监测故障智能诊断系统。通过实时监测外输泵机组振动、转速和油温等参数,实现了就地和远程在线监测外输泵机组的运行状态,及时诊断故障结果和提出预知性维修指导意见,确保了外输泵机组安全可靠地运行,延长了无故障使用期限,从而避免了非计划停机,节省了运行和管理费用,提高了生产效率。经2016年在长庆油田第三采油厂3个增压点的现场应用,满足了该油田绿色数字化油田发展的要求。

Aiming at the problem in actual application, on-line monitoring intelligent fault diagnosis system for external transmission pump intelligent fault diagnosis system is developed. It is mainly composed with 5 parts of detection composite sensor, collector, multi-port transmitter, local monitoring unit and remote monitoring unit. Through real-time monitoring of external transmission pump units vibration, speed and oil temperature and other parameters, running status of local and remote on-line monitoring of the pump units, timely fault diagnosing result and prediction guidance being put forward are realized. Safe and reliable operation of external transmission pump units is guaranteed. Fault free application period is extended. Unplanned shutdown is avoided with saving operation and management cost. The production efficiency is improved. The field application is carried out in three pressure points in third oil production plant of Changqing Oilfield in 2016. The requirements of development of Changqing green digital oilfield is fulfilled.
