Abstract
Nowadays, reducing the share of energy losses from the total oil wells’ energy consumption is becoming a central objective. This publication purpose is to assess the energy-saving effect of the downhole reactive power compensators’ used in the composition of the electric centrifugal pumps. The function E E characterizing the effective use dynamics of the consumed active power by installation before and after compensation of reactive power in a well is offered. The surfaces of the E E function are constructed. They depend on the power of the submersible induction motor, the length and cross section of the cable line, which can be estimated energy-saving effect when using downhole compensators. It was found that the calculated indicator of the E E function varies from 0.6 % to 15.8 % depending on the submersible motor’s power, the power of the downhole compensator, the length and cross section of the cable line. The expediency using of the downhole compensators in the composition of electric-center pumps at the oil production facilities is substantiated.
