FIELD: geophysical equipment, particularly technical means for cased well wall perforation.
SUBSTANCE: system comprises mechanical pressing device to be suspended to tubing string and having channel for flexible shaft receiving. The system also has downhole equipment including hardware kit delivery block. The delivery block comprises downhole measurement tool, hydraulic rotor drive, compensator, which applies load to drilling tool, flexible shaft for drilling tool hear fixation. Downhole equipment includes suspension means made as logging cable. Delivery block has anchor-type braking device provided with electric drive for hardware kit retention in tubing string and extendable telescopic device to supply drilling tool to perforation interval.
EFFECT: increased reliability and productivity, as well as increased reservoir penetration efficiency.
