METHOD FOR EXTRACTING AN OIL DEPOSIT

FIELD: oil extractive industry. ^ SUBSTANCE: method includes feeding of water along pipeline through mouth locking armature to input of single pump, pumping of water into force well along tubing pipes by said single pump while providing for necessary pressure, and extraction of oil through product wells. Firstly, extraction is performed with pumping of working agent in cyclical mode from pump station until finding sectors with low bed pressures. At deposit portion with lowered bed pressure a single pump is placed on day surface on mouth of force well. Effectiveness of single pump is selected to be enough for providing for maximum well acceleration. Working agent is pumped by said pump in individual mode through force well until restoring bed pressure and increasing debits in all surrounding product wells. Product wells are stopped in turns starting from first reacted to last reacted on operation of said pump. Said pump is switched off and pumping of working agent in cyclical mode is continued from pump station. ^ EFFECT: easier pumping of water into force well. ^ 1 ex
