FIELD: mining; oil and gas production.
SUBSTANCE: group of inventions relates to mining, oil and gas production, to devices for repairing oil and/or gas wells using perforation and formation hydraulic fracturing and can be used in the implementation of methods for enhanced hydrocarbon production. The device contains a packer and a perforator installed on the oil well tubing, in the body of which at least one circulation window is made for pumping a working fluid into the well, destructive elements for perforation, a mechanism for singulating the circulation windows and destructive elements. Area S of the flow area of the circulation window/circulation windows has a value in the range: 103.9 mm2 < S < Stubing, wherein Stubing is the cross-sectional area of the pipe suspension used for hydraulic fracturing. Circulation windows can be made in an additional branch pipe.
EFFECT: invention improves durability and reliability.
