It is noticed that at a capacity choice of the submersible electric motor it is necessary to consider factor of a stock which provides working capacity of installation on speeds above nominal, losses in the frequency converter and falling of efficiency of the electric motor at work with the frequency converter. The formulas are expressed, allowing to define the minimum necessary specific energy consumption on cubic meter of a pumped out liquid from a well at target production rate. It is shown, what not always it is seem possible to pick up precisely the equipment for an optimum variant. Therefore the algorithm of selection of the submersible pump, the electric motor, the connecting cable, the raising transformer and control station from the discrete series which is let out by the industry is resulted. The analytical expression is received, allowing to define the parameters of a working point at the head curve of the submersible pump. The concrete example of a choice of the equipment of the electric submersible pump is considered. It is noticed that application of the frequency converter in control station can lead to the additional expenses of electric energy reducing power efficiency of the electric submersible pump.power efficiencysubmersible pumpsubmersible electric motorspecific energy consumptionэнергетическая эффективностьпогружной насоспогружной электродвигательудельное потребление электроэнергии[Тарасов В.П.
