A procedure for treating the perforations of a well, in particular by intervention of a cable, in order to plug them or consolidate them comprises the successive steps of:(a) arranging, close to the perforation to be treated (50, 54), a dehydration powder chamber (32) that produces a large volume of high pressure gas at a high temperature, as well as a composite powder chamber (40) designed to treat the perforation (50, 54);(b) igniting the dehydration powder; and(c) once the combustion of the dehydration powder is completed, igniting the composite powder so the treatment of the perforation (50, 54) can take place.The invention also relates to a device for implementing this procedure.
