FIELD: oil and gas industry.
SUBSTANCE: lining powder pressure generator for hollow-carrier jet-type perforators and implosive devices is made in the form of common tubular lining charge fixed on the housing of the device. Common tubular lining charge is made in the form of a set of fragments subsequently fixed on the device housing one after the other. At that, fragments are made of rod elements of ballistite cannon powder in the form of homogeneous constructions in the form of pipe by bonding the edges of powder elements by cold curing polymer or in the form of flexible plates by binding powder elements by means of nitrocellulose or cotton band.
EFFECT: improving efficiency of action of charges and simplifying the charge manufacturing procedure.
