FIELD: oil and gas production, particularly perforators and permeators used for perforating-explosive operations in oil and gas wells.
SUBSTANCE: shaped-charge gun has sealed body. Installed in the body are perforated pipe and charge initiation means. The perforated pipe is used for hollow charge orientation. The hollow charges are oriented in pairs. Two charges forming one pair are oppositely directed one relatively another. Lower neighboring pair of hollow charges extends at obtuse or oblique angle to upper one.
EFFECT: increased reliability and efficiency or well perforation.
