Four-knife perforators

The perforator is designed for the secondary opening of productive formations of oil and gas wells by forming longitudinal slots and blurring the bottomhole zone through these slots.

The perforator allows you to simultaneously form 4 slots with a phasing of 90 degrees and simultaneously wash 8 caverns to a depth of one meter.

A distinctive feature of the models of size 146 and larger is the ability to mount the downhole motor and reamer to the bottom connection thread and to perform reaming before and after well perforation in 1 downhole operation.

The design allows the following operations to be carried out through the technological holes of the perforator:

• replacement of well fluid volume before and after perforation;
• acid treatments;
• well development by compression, swabbing, including hydrodynamic research.

The perforator allows you to kill the well after cutting the downhole valves.
