Beschreibung
Zusammenfassung:	FIELD: explosive operations technology. SUBSTANCE: device has hollow charges, detonation means, U-shaped cartridge clips with opening in the middle portion for fixing the charge, terminal parallel racks placed at angle of 90 degrees to perforator axis. Cartridge clip is made of protective screening metal with opening in each terminal rack for interconnecting cartridge clips by means of bolts for forming a frame of needed length with capability of placing charges in each cartridge clip. Terminal racks are made in relationship of F=(0.5...0.8)D and L=(1.3...1.7)F, where L and F are accordingly length and width of terminal racks, D - charge diameter. EFFECT: possible perforation of passages at angle to well wall and lessened mutual effect of nearby hollow charges explosions. 2 cl, 4 dwg
