FIELD: oil and gas industry.SUBSTANCE: invention relates to oil and gas industry and can be used to increase efficiency of development of low-permeability productive formations. Method involves drilling of wells with hydraulic fracturing in each borehole of these wells and injection of displacement agent in production well feeding area. At that, at selected section of formation directions of main compressive horizontal stresses in bed are determined. Drilled at least two branched wells. Faces of these wells are arranged along common line directed mainly towards minimum compressive stresses in bed, with successive alternation of faces. Both wells operated as production to elastic energy depletion of formation fluid. After that, injection of displacement agent through one of wells is performed.EFFECT: improving development efficiency of low-permeability productive formations at reduction of labour intensity of development.2 cl, 1 ex, 2 dwg |
