Development of a Method for Optimizing Power Consumption of an Electric Driven Centrifugal Pump

Abstract

Oil production is a complex technological process involving subsystems of different physical nature. The common power-consuming equipment of the electric drive centrifugal pump installation is electric motor, which drives the pump. When the well flow rate changes, the equipment parameters are changed, as a rule, empirically. In this regard, the development of an analytical method for selecting the parameters of electrical and technological equipment, taking into account technological restrictions, is an important task. Based on this model, a technique has been developed for selecting the optimal control station frequency and the choke diameter in terms of reducing electrical submersible pump installation losses. The proposed methodology analytically takes into account the equipment limitations and technological limitations. The application of this technique allows to achieve the optimal control of the well flow rate from the standpoint of energy efficiency, taking into account various restrictions.
