What is a Mechanical Tubing Punch?
The Mechanical Tubing Punch is designed to be able to punch holes in downhole tubing. After jarring down to shear a shear pin, the perforating punch is pressed against the tubing wall by pulling up on the tool string followed by upward jarring. Once the hole has been made in the tubing the punch will retract into the tool allowing the tool to be pulled from the bore. It is used to aid in the draining of fluid from the tubing when the tubing needs to be removed from the well. It can also be used as a method to allow communication between the tubing and casing for injection of chemicals or to circulate kill fluid. Another use is to allow additional productive zones to be introduced to the production string when required.
Applications
- Draining fluid from the tubing when it needs to be removed from the well.
- Communicating between the tubing and casing.
- Selectively perforating the inner pipe without damaging the outer casing or annular string.
Key Features & Benefits
- Operates without explosives, enhancing safety during handling and logistics.
- Multiple tool sizes for a variety of tubing diameters.
- Utilizes upward jarring to punch holes.
