FIELD: oil and gas industry.
SUBSTANCE: method consists in hydraulic fracturing of a well shaft using a drilling column and involves the stages at which the following is performed: lowering of a drilling column into a well shaft; pumping of fluid medium at least to one internal passage in the drilling column and in annular space between the well shaft wall and the drilling column; measurement at least of one of fluid medium pressure and temperature parameters near lower end of the drilling column; transfer of measurement data to surface, essentially, together with measurement, control signals are transferred from a controller to the drilling column to perform at least one of the following: inflation of a packer, pumping-out of a packer, blockage of fluid medium flow and initiation of cumulative charges.
EFFECT: increasing the efficiency of the method.
