Research and application of intelligent control system for variable speed operation of pumping unit

摘要

At present,the pumping machine lifting technology still has problems such as low efficiency,high energy consumption and short pumping cycle.In order to further improve the level of artificial lifting technology of pumping wells,achieve quality and efficiency,save energy and consume reduction,huabei oilfield has developed an intelligent control system for variable speed operation of pumping unit,which takes"closed-loop control technology","flexible control technology"and"variable speed operation technology"as a core,and sets digital supporting technology such as"mobile intelligent management and control","big data analysis"and"OPRS intelligent expert"as a whole.The system successfully applied more than 600 wells in Huabei Oilfield.Through large-scale on-site application,intelligent control system for variable speed operation of pumping unit realizes the most economical production with minimum energy consumption,achieves the goal of energy saving and consumption reduction,and enhances the intelligent production management level of the oilfield.
