METHOD OF DEVELOPMENT OF OIL RESERVOIR Russian patent published in 2008 - IPC E21B43/20 

FIELD: mining.

SUBSTANCE: method includes pumping of water via input wells, withdrawal of oil via producing wells, conversion of watered producing wells into input ones, selection of producing well which first reacted to pumping with premature inrush of pumped water, limitation of oil production up to complete well shutdown and at absence of reduction of watering conversion of well into input one. According to the invention the volume of water, pumped into the input well, from which the producing well transferred for input has been watered, is distributed uniformly for both mentioned wells at maintaining the balance of pumped water volume into input wells and withdrawal of oil from producing wells in formation conditions.

EFFECT: upgraded efficiency of method by means of increased oil withdrawal from reservoir.
