FIELD: oil and gas production.
SUBSTANCE: invention refers to perforation equipment at perforating operations in oil production. The method consists in producing source item out of copper wire, in its deforming to obtain a required shape and in low-temperature annealing of the produced workpiece. Copper wire is subject to intensive plastic deformation; also low-temperature annealing is carried out during 0.5-1 hour at temperature by 20-40°C exceeding temperature of copper crystallising beginning.
EFFECT: increased depth of perforating.
