Reservoir Group Well Intervention Products & Services’ Down-Acting Impact Hammer is a tool that transmits multiple downward impact forces at high frequency, thus eliminating the need to cycle the Coiled Tubing at surface and reducing fatigue on the coil.
The tool is operated by a combination of flow rate and set-down weight which is converted into mechanical energy. The Down-Acting Impact Hammer is constructed with a single-piece, non-flexible impact shaft for maximum impact force and power efficiency. It is also available in 1.69” OD & 2.13” OD sizes.
Transmission
The Impact Hammer has a single-piece, non-flexible shaft; it is the simplest and most reliable means of transmission for all applications in an impact drill.
Power Section
The Down-Acting Impact Hammer has a non-typical power section which does not rely on rubber components for efficient operation. The tool is constructed from aviation-quality stainless steel for use in hostile environments such as H2S, CO2, HCl and can be operated with a variety of fluids including diesel, foam, light oils, nitrogen gas and in high temperature applications.
Bearing Assembly
The Impact Hammer Drill Jar’s bearing assembly is well-suited for weight-on-bit (WOB), side-loading and over-pulls. Non-typical bearings are used, eliminating common problems of lubrication failure and over-heating.
Applications
Shifting Sliding Sleeves and Isolation Valves
Breaking Ceramic Discs
Swaging & Broaching Operations
Driving Debris and Stuck Tools Down-Hole
Cleaning Sand & Scale
