Working Condition Diagnostics System for Electrical Submersible Pump in Geothermal Well

The situation of the global energy is tending to be in short supply, but geotherm is the inexhaustible renewable energy. Extracting reservoir geothermal water from old oil well can achieve economic benefits of oil - heat joint production. Since 2005, Huabei oilfield has been engaging in geothermal comprehensive utilization research projects and developed the large displacement electrical submersible pumps suitable for high temperature. For the operation management of this equipment, the working condition diagnosis analysis research has been carried out, 16 kinds of current curve template and 73 kinds of pump characteristic curve template have been established using ADO remote data access technology, and the volume efficiency and energy efficiency dynamic control model and chart have been established as well. The production situation analysis using the chart can timely find out the problems existing in the production and puts forward the improvement measures to achieve the purpose of energy saving and consumption reduction.
