Thermal Drilling TRIZ Cases
- Coil Spring Corrugated Waveguide Assembly for Long-Length Precision
A coil spring nested in a tube forms corrugations for long waveguides, cutting machining errors, waste, and transmission loss.
- Multi-Piece Corrugated Waveguide Using an Internal Coil Spring
A coil spring inside a tube creates precise corrugations for long waveguides, reducing manufacturing errors, waste, and repair cost.
- Downhole Laser Beam Combining for Low-Loss Deep Perforation
Multiple low-power laser beams are combined downhole to cut energy loss and heat buildup during deep perforation and boring.
- Exothermic Torching Rod for Quiet Cutting and Oxygen Delivery
Stainless steel fiber torching rods create a quieter oxygen-fed cutting path while avoiding magnesium hazards and supporting breathable oxygen delivery.
- Radial Laser Cutting Head With Cooling Nozzles for Controlled Fractures
Radial laser cutting with parallel cooling nozzles creates controlled transverse fractures while limiting heat damage and bypassed reservoir zones.
- Thermal Lance Ignition Cartridge with Induction Preheating
Induction preheating of a fuel-filled cartridge enables remote thermal lance ignition without manual torches or hazardous pyrotechnics.
- Laser Stimulation Tool Using Activating Agents for Reflective Formations
Applying a high-absorption agent before lasing helps reflective formations absorb more energy, reach higher temperatures, and improve stimulation.
- Downhole Laser Tool Beam Steering for Wellbore Expansion
Rotating and tilting a high-power downhole laser helps reshape wellbores, create inclined paths, and improve hydrocarbon-water separation.
- Laser Stimulation Tool Using Activating Agents for Reflective Formations
Applying an optical absorbing agent before laser exposure boosts formation heating and ablation in reflective, low-permeability wells.
