K-Punch Electro-Mechanical Punching Tool
Using modular structure, the punching module is directly connected to the setting tool, a five-module tool is formed, which contains battery - motor - gearbox - pull rod - punching module. The Punch Tool utilises the K-Set’s 10 inch stroke to both deploy and retract the Punch button in a single stroke.
Application
- Punch hole for tubing/casing, be able to penetrate through alloy tubing or thick wall tubing
Characteristics
- Powered by K-Set as a Down Hole Power Unit, modular structure, safe and reliable, easy to use and maintenance.
- Can be used by E-line/slickline/coiled tubing
- Punch automatically by countdown trigger when RIH by slickline
- Control tools and feedback data in real time when RIH by E-Line
- Large and continuous pressure on the small section will not deform the tubing
- Suitable for tubing grade J-55, L-80 and P-110
- Can be configured to punch single or multiple, oriented holes in a single run.
Advantage
- Punch hole and retract the punch button in a single stroke
- Avoid the cost and red tape of gunpowder transportation approval
- No special gunpowder qualification is required for operation
- The operation is extremely simple and compliant with HSE standards
- Compared with gunpowder punching and traditional mechanical punching, cost saving
- The problems such as low success rate of traditional mechanical punching tools and limited target tubing are eliminated
- It will not affect the annulus and will not cause damage to the casing
