Beschreibung
Zusammenfassung:	production of liquid; attaining steady-state conditions and maintaining these conditions in case of change in stratum parameters. SUBSTANCE: method is based on frequency regulation of speed of induction motor of submersible pump by deviation of present magnitude of dynamic level from preset magnitude. Present magnitude of dynamic level is determined in the course of successive actions with signals pertaining to flow rate at well discharge and frequency of voltage of power converter. Device for realization of this method is provided with new couplings between units. EFFECT: enhanced reliability; simplified construction; possibility of attaining required mode of operation of well. 3 cl, 2 dwg
