Abstract: The statistics show that the electric power consumption in water flooding development takes up 33%~56% in the total power consumption of oil production.The energy-saving problem is emergent in water flooding system.The pump-control-pump(PCP) technique based on two pumps connected in series is put forward to regulate the output pressure and flux of water flooding system and to make the high-pressure and high-power water flooding pump working with high efficiency by means of preceding booster.The mathematical models for the control system were established on the basis of the superposition characteristic analysis of pumps used in large-scale water flooding station.The automatic control theory and energy-saving principle are introduced.The output pressure and flux of water flooding station are taken as the objective functions,and high efficiency,energy-saving and optimization operation are realized in high-pressure water flooding station.
