FIELD: oil and gas.
SUBSTANCE: present invention relates to the oil and gas industry, namely to the well field. The set of devices for well perforation contains perforating gun sections connected between themselves, a casing, supporting and guiding components. The casing wall has horizontal tapered openings and protection rings coaxial with the horizontal openings. The cylindrical surfaces of the perforating gun section shells are furnished with through slots consisting of a conical part and a longitudinal part, so that the conical parts of the adjacent slots form a conical ledge. The shell has horizontal openings and a vertical axial opening, white the adjacent section shell ends have a flexible coupling attached thereto and consisting of a sphere and a shell assembled of two parts and encircling the sphere. The horizontal openings of the perforating gun section shells are connected to a compressed air feeding hose by a vertical opening.
EFFECT: simplified design of perforating gun, increased reliability, efficiency of hole perforation in casings and formation.
