Abstract
The purpose of the article is to determine the optimal parameters inside the downhole compensator of the reactive power at which minimization consumption of active power is provided. The energy-saving function for electric effect estimating with the use of the downhole compensator is propoused. Surfacing energy-saving functions are received. Their analysis showed that minimal consumption of the submerged motor reactive power is achieved by tre power of inside downhole compensator 0.92 with the submersible motor power.
Highlights
The real share of hard-to-recover hydrocarbon reserves in Russia and in the world is increasing nowadays [1,2,3]
The active power is Рi, consumed by the ESP. It is expended on useful work performance by submersible electric motor and loss in conductive elements of electrotechnical complex. It depends on the power of submersible electric motor and reactive power of the compensating system: P=i Pm + ∑ ∆P= Pm + ∆PТ + ∆РCL + ∆Рm, (1)
The submersible electric motor is supplied with the power from transformer brand TMPN250/3 in the analyzed electrtechnical complex ESP
Summary
The real share of hard-to-recover hydrocarbon reserves in Russia and in the world is increasing nowadays [1,2,3]. To maintain the planned volume of extracted oil-producing the oil companies increase the productivity of pumping plants.After this case, the power consumption of submersible electrical equipment is increasing. Among the factors affecting improving the energy performance of oil production in the watercut changing, it is possible to emphasize the watercut liquid reduction [5,6,7] and compensation of power losses in elements of oil production installations [8, 9]. 13], the production process management [14], the quality of electricity improving [15], the hydraulic losses reduction by the pump-compensating pipes of maximum diameter using [16, 17] The increasing of efficient energy exertion in oil production is achived by energy efficient equipment with the highest efficiency [10, 11], the optimization in downhole equipment selection [12. 13], the production process management [14], the quality of electricity improving [15], the hydraulic losses reduction by the pump-compensating pipes of maximum diameter using [16, 17]
