Abstract

Устройство для создания перфорационных каналов в скважине, включающее корпус, клин с пазами, по меньшей мере, два размещенные друг за другом гидроцилиндра с соединенными шток-поршнями, один из которых подпружинен, и, по меньшей мере, два резца с гидромониторами и резцедержателями, размещенными в пазах опоры и клина с возможностью радиального возвратно-поступательного перемещения, отличающееся тем, что корпус образован клином и стенками гидроцилиндров, шток-поршни которых выполнены с осевым каналом, сообщенным переточными каналами с их подпоршневыми полостями, а трубками - с гидромониторами резцов через каналы резцедержателей, опора которых соединена с шток-поршнем, подпружиненным вниз относительно гидроцилиндра.A device for creating perforation channels in a well, including a housing, a wedge with grooves, at least two hydraulic cylinders placed one after another with connected piston rods, one of which is spring-loaded, and at least two cutters with hydraulic monitors and tool holders placed in the grooves of the support and the wedge with the possibility of radial reciprocating movement, characterized in that the housing is formed by a wedge and the walls of the hydraulic cylinders, the piston rods of which are made with an axial channel communicated by transfer channels with their dporshnevymi cavities and tubes - with jetting cutters through channels toolholders, support which is connected to the piston-rod, a spring-loaded downwards relative to the hydraulic cylinder.
