FIELD: gas-oil industry. SUBSTANCE: off-gas flows are pumping out by debit hole (C) using from gas zone above water surface to form workable oil cone so good as it is possible by setting on pumping rate using in hole mouth of gas-oil bed contact. Oil is pumping out from contouring oil through oil cone made preliminary. Gas is repumping to zone of gas bed to overpressing gas bed. Gas and oil extraction is making in turn, but operation rate is growing up slowly to prevent water cone formation in floor working. EFFECT: better efficiency of oil extraction from floating oil bed. 2 cl, 7 dwg
