FIELD: oil and gas production.
SUBSTANCE: procedure for firing perforation holes from well borehole in adjacent underground formation includes following operations: arrangement of well firing perforator in well borehole, also, perforator contains group of charges of explosive substance firing perforation holes in reservoir adjacent to well, detonation of group of charges of explosive substance to fire first perforation hole in reservoir, and firing pair of second perforation holes crossing at point behind final point of first hole.
EFFECT: raised efficiency of reservoir exposure.
