Small-sized cumulative rotary hammer with a removable frame, lowered on a wireline cable is designed for secondary opening of formations in cased wells filled with liquid or gas.

The perforator consists of sealed cumulative charges placed on a steel frame of segment rolling. Perforator versions differ in the conventional length of the frame - 1 and 2 meters.
The perforator has an optimal design for use when opening productive formations through tubing with a sealed mouth, including when perforating in a depression.

The hammer drill is certified according to API RP 19B.

Application features

  • Improved self-orientation in the casing, contributing to the depth of penetration of the charge;
  • Increased patency in directional wells and wells with heavy and viscous solutions;
  • Slight deformation of the shot assembly, ensuring its reliable extractability;
  • Wide range of working pressure;
  • Manufacturability of a perforator for use in wells with a small bore.
