FIELD: machine engineering.
SUBSTANCE: perforator comprises a body and a working unit arranged therein with a mechanism of its initiation, it additionally contains a distributing unit for controlling the flow of working fluid providing controlled delivery of fluid to the working unit of the perforator or into the lower part of the perforator bypassing the working unit.
EFFECT: performing in a well one pulling and running operation in conjunction with perforation of other technological operations, implementation of which together with perforation requires feeding of working fluid under the perforator to the equipment located in arrangement below the perforator, or into the annular space.
