Capsule-type expendable perforation system Strip 43-AT
Download
Application:
Opening formations in oil, gas and other wells, fixed with a casing string and filled with water, oil or flushing fluid, by creating channels in the rock in order to form a hydrodynamic connection between the formation and the well, when the tubing is lowered and the wellhead is sealed, including the cases of the pressure drawdown and the lowered level of liquid in the well.

Advantages and features:
- it is possible to work in the well when the tubing is lowered and the wellhead is sealed, including the cases of the pressure drawdown and the lowered level of liquid in the well;
- the retrievable carrier allows to minimize clogging of the well with perforator fragments;
- the perforator has a small blasting impact on the walls of the casing string and can be used at low hydrostatic pressures;
- the perforator is characterized by an increased penetrative power.
