FIELD: oil industry; explosive devices.
SUBSTANCE: invention relates to explosives completion fluids in oil wells and may be used in the shaped-charge warhead. Shaped charge comprises a housing with an explosive cartridge disposed therein having a cumulative recess with lining consisting of two layers made of different materials, the outer layer adjacent to the cumulative recess and an inner jet-forming layer is made of copper, and the outer and inner layers of cladding are positioned relative to each other with a gap of no more than two thicknesses of the wall of the outer cladding layer and the outer layer is made of a lining material density of 2-3 g/cm3, for example sodium chloride NaCl.
EFFECT: technical result of the invention is to increase the penetration and stability of the shaped charge in the absence of slug-forming.
