Claims (5)

1. Секторный способ щелевой гидромеханической перфорации скважины, включающий формирование перфорационного канала в обсадной колонне механическим способом : выдвижным от давления нагнетаемой рабочей жидкости раскатным диском и возвратно-поступательным движением перфоратора путем подъема и опускания колонны насосно-компрессорных труб, а в цементном слое, сложно-напряженной прискважинной зоне и продуктивном пласте - гидравлической струей, вытекаемой из сопла насадки направленного вверх под углом 45° к стенке скважины, отличающийся тем, что сопло насадки в процессе перфорации имеет возможность постепенно изменять направление струи вниз до угла 45° к стенке скважины, после сброса рабочего давления сопло имеет возможность возвращения в исходное положение, для чего используют известный перфоратор с гидроцилиндром, поршень которого связан с раскатным диском, и дополнительно полый шток гидроцилиндра содержит гибкий шланг высокого давления с корпусом гидромониторной насадки, корпус насадкодержателя соединен подвижно с корпусом устройства с возможностью качения в вертикальной плоскости и связан со штоком, содержащим шатун с двумя осями вращения, с возможностью качения в этой же плоскости.1. Sectoral method of slotted hydromechanical perforation of a well, including the formation of a perforation channel in the casing by a mechanical method: by a sliding disk, which is retractable from the pressure of the injected working fluid, and by the reciprocating movement of the perforator by raising and lowering the tubing string, and in a cement layer, it is difficult to strained borehole zone and reservoir - a hydraulic stream flowing from the nozzle nozzle directed upward at an angle of 45 ° to the wall of the well, characterized in that the nozzle nozzle in the process of perforation has the ability to gradually change the direction of the jet down to an angle of 45 ° to the wall of the well, after the operating pressure has been relieved, the nozzle has the ability to return to its original position, which uses a well-known perforator with a hydraulic cylinder, the piston of which is connected to the rolling disk, in addition, the hollow rod of the hydraulic cylinder contains a flexible high-pressure hose with a body of a hydraulic nozzle, the nozzle holder body is movably connected to the device body with the possibility of rolling in vertical Flax plane and is connected to the rod comprising a connecting rod with two axes of rotation, with the possibility of rolling in the same plane. 2. Секторный способ гидромеханической перфорации по п.1, отличающийся тем, что щель в тубе обсадной колоны создают в два этапа: вначале механическим резцом и затем раскатным диском, а секторную выработку в пласте - качающейся гидромониторной насадкой.2. The sectoral method of hydromechanical perforation according to claim 1, characterized in that the gap in the casing tube is created in two stages: first, with a mechanical cutter and then with a rolling disk, and sector production in the formation with a swinging nozzle. 3. Секторный способ гидромеханической перфорации по п.1, отличающийся тем, что щель в тубе обсадной колоны создают механическим резцом, а секторную выработку в пласте - качающейся гидромониторной насадкой.3. The sectoral method of hydromechanical perforation according to claim 1, characterized in that the gap in the casing tube is created by a mechanical cutter, and the sector output in the reservoir is created by a swinging hydraulic nozzle. 4. Секторный способ гидромеханической перфорации по п.1, отличающийся тем, что щель в тубе обсадной колоны создают диском-фрезой, а секторную выработку в пласте - качающейся гидромониторной насадкой.4. The sectoral method of hydromechanical perforation according to claim 1, characterized in that the gap in the casing tube is created by a cutter disk, and the sector output in the formation is created by a swinging hydraulic nozzle. 5. Секторный способ гидромеханической перфорации по п.1, отличающийся тем, что корпус гидромониторной насадки установлен в корпусе полого штока с возможностью качения в вертикальной плоскости и соосно жестко соединен с шестерней зубчатой рейки, установленной подвижно в дополнительных направляющих опорах, жестко связанных со штоком, рейка расположена между дополнительными упорами корпуса устройства. 5. The sectoral method of hydromechanical perforation according to claim 1, characterized in that the housing of the hydraulic nozzle is mounted in the housing of the hollow rod with the possibility of rolling in the vertical plane and coaxially rigidly connected to the gear of the rack mounted movably in additional guide bearings rigidly connected to the rod, The rail is located between the additional stops of the device.
