INSTALLATION FOR POWER SUPPLY OF IMMERSED ELECTRIC ENGINE AND/OR WELL FLUID HEATING Russian patent published in 2011 - IPC E21B36/04 

FIELD: gas and oil production.

SUBSTANCE: installation consists of immersed electric engine, of control station, of matching power transformer and of station for heating control. The station for heating control consists of a control unit, of a low frequency generator with the range of frequency 5-200 kHz, of a rectifier and of power output keys. The installation is equipped with two matching devices. The first device is an above-ground one and through its two inputs it is connected with the heating control station and the matching transformer correspondingly, while thought its output it is connected with an electric communication line. The second matching device is immersed. By means of the electric communication line it is connected with the first matching device through input, while through output it is connected with the immersed electric engine. Equivalent capacity of the matching devices is within the ranges 0.2-200 mcF.

EFFECT: expanded functional and process capacities of installation.
