FIELD: oil and gas industry.
SUBSTANCE: device includes wire-line, unpackaged cylindrical propellant charge with igniter and accessories. According to invention the propellant charge is closed by rigid combustible bag that provides the reduction of charge deformation at high temperatures in well and generation of additional energy quantity. Rigid combustible bag consists of the following components, wt %: thermosetting polymer compound - 30…37; pyroxiline fibre - 18…22; explosive component - 42…48 and plus 100%: ethyl alcohol - 10, wetting agent - 0.1.
EFFECT: increase of device operation reliability at increased temperature influences.
