PROCEDURE FOR STIMULATION OF OIL OUTPUT AND EQUIPMENT FOR ITS REALISATION Russian patent published in 2011 - IPC E21B43/16 

FIELD: gas-and-oil producing industry.

SUBSTANCE: according to procedure payout bed is effected with electro-magnetic resonance by means of sources of electro-magnetic oscillation immersed into wells. These oscillations are excited with electric dipoles arranged in each pressure and producing wells. Inputs of all electric dipoles of pressure wells are connected to one circular feeding cable. Electric dipoles placed in each producing well are connected to another circular feeding cable. Also, during the first time half-cycle voltage supplied to input of dipoles installed in the pressure wells is of higher amplitude and opposite polarity, than voltage supplied to input of dipoles in producers during the second time half-cycle. The said circular cables are fed in pairs as oil is extracted from volume of the bed enveloped with working inter-well circular electric dipole. Feeding voltage is switched to a following pair of circular electric dipoles. Supply of power of said intra-well circular electric dipoles is coordinated with extracted summary output of producers; when it decreases, power consumption of operating circular electric dipole is increased maintaining output within maximal limits.

EFFECT: raised oil output of bed due to controlled different-pulse electro-magnetic effect to intra-well space facilitating flow of residual oil to side of producers.
