Usage of submersible electrical motors with raised pressure provides double effect without investments
The paper considers the problem of heat losses decrease in submersible cable due to lowering of operational current of submersible electrical motor, which is reached by means of its nominal voltage increase. Usage of submersible electrical motors with increased voltage allows 5...7 % lowering of electric power consumption. Decreasing effect of electric voltage consumption is increased proportionally to a cable's length. Usage of submersible electrical motors ensures simultaneous reduction of costs spent on purchasing of electric power and a set of electrical centrifugal pump unit, thus, being very important in case of low-profitable wells. The paper presents some field-testing results being the basis for economic effect calculation. Application of the technology allows either complete absence of investments or some small initial investments which will be paid back within 2...6 months.
