In each of such wells, the first MHF is performed, during which the fracture propagation area is recorded by means of low-frequency seismic survey. Packers separate the horizontal wellbores into sections, then the wells with conducted MHF are injected, through each horizontal wellbore section, with insulating composition with the following component ratio, wt %: SAW - 0.2-5.0, PAA - 0.005-2.5, chromium acetate - 0.01-1.0, filler - 0.5-15.0, water with a salinity of less than 1.5 g/l - the rest.
