FIELD: oil and gas industry.
SUBSTANCE: installation includes device for orientation and device for perforation. The device for orientation contains connected in series with each other orientator, lock device and diverter with sub, at that orientator is made with displaced centre of gravity for the diverter orientation. The device for perforation contains connected in series interface attachment, device to monitor orientation, and drilling perforator with hollow flexible shaft and cutting tool. The interface attachment is made with possibility to connect and to interact with diverter sub. Installation has transportation assembly secured on the geophysical cable with possibility of engagement and disengagement with the diverter sub and perforator.
EFFECT: implementation of the perforation mode ensuring maximum depth of created channel, absence of negative effect on the operation string and cement stone, necessary orientation of the perforator under azimuth, possibility of check of the perforator installation in necessary direction, and simple installation.
