FIELD: oil and gas production. ^ SUBSTANCE: drilling perforator comprises a system of perforator fixation to a well wall, a system of perforation, comprising a hydraulic cylinder of perforation, a drill, a curvilinear guide for a drill, a system of drill feed with a hydraulic cylinder of drill feed. The system of perforator fixation to the well wall comprises the second and third hydraulic cylinders, a system of drill inclination angle adjustment comprises a distributor, a hydraulic cylinder and a displacement sensor. Systems of fixation, perforation, drill feed and drill inclination angle adjustment are combined into a single electric hydraulic system with logical control and a controller. ^ EFFECT: higher reliability of perforator operation, application of a modular design for operation on wells of different diameters, improved automation of fixation and unfixturing, elimination of high accident risk of works, improvement of a perforator. ^ 1 dwg |
