Modernized pipe puncher PTM is designed for punching 825 mm holes in tubing and casing from 60 to 168 mm of domestic and foreign manufacturers to make a communication between the interior cavity and the exterior annular space. This hole provides circulation restoring, prevents pulling pipes with fluid out of wellbore, and refilling into cement sheath and decreases environmental pollution while well workover operations.

Punchers are produced of several series: ordinary K, for application in gas medium G, for application at depth 3000-6000 m VD.

Punchers are run in a hole on wire, cable, flush-joint pipes or by throwing off.

Potential energy of a fluid column and pumping unit pressure are used to actuate a puncher.
