ZKPO-PP-ZDK puncher-type shaped charge as a component of KPO36 version DK was designed to solve tasks connected with restoraon of circulaon between the tubing and the casing annulus.
Specific feature of this gun type is no-damage to the casing adjacent to the tubing aer shoong. Due to the constant pressing of the gun body to the internal wall of the tubing and linear arrangement of charges with 0° phasing, guaranteed penetraon of 1 to 6 (depending on the number of installed charges) holes in the tubing wall is ensured.

* Can change depending on mechanical properes of carrier tubes.
** Can be limited by maximum allowable temperature for explosives contained in the guns.
*** Actual hole diameter may differ from the indicated one, depending on the tubing strength group, but is not less than 2 mm for any strength group.
