FIELD: oil and gas industry.SUBSTANCE: method involves water pumping to a productive formation with simultaneous wave action. According to the invention, at development of floating oil deposits with production wells with horizontal shafts crossing definitely oriented vertical planes of fracturing, injection horizontal wells are located at the level of oil-water contact (OWC) or below it in water-bearing parts of the formation. With that, horizontal shafts of injection wells intersect the planes of vertical fracturing as production wells. Temporary shutters or liquid filtration controls are installed in production wells at fracturing intervals, and wave emitters at those intervals are installed in injection wells perforated at fracturing intervals. Uniform lifting of OWC with displacement of oil to horizontal shafts of production wells is provided by means of wave action.EFFECT: invention provides the possibility of displacement of residual oil from deposit blocks with vertical fracturing.2 cl, 1 dwg |
