FIELD: oil-and-gas industry.
SUBSTANCE: proposed method comprises determination of pool fracturing or softening lines, construction of production and injection wells with allowance for formation fracturing, injection of displacing agent in injection wells and oil withdrawal via production wells. In compliance with this invention, area of the 10 m-deep oil-saturated pool is selected whereat quick flooding of extracted oil with bottom water is ruled out. Location of softening nodes, an intersection of softening lines, is determined. Vertical production wells are drilled in irregular spacing to get to softening nodes or as lateral or lateral horizontal shafts with crossing of adjacent softening lines connected with softening nodes. Injection wells are located in compacted carbonate reservoirs with minimum and mean fracturing between several softening nodes at equal distance therefrom.
EFFECT: higher oil yield and efficiency of development.
