Amazing New drilling technology ,Flow Drilling Examples of new drilling technologies There are more than 20 research efforts solving innovative drilling technology such as: laser, spallation, plasma, electron beam, pallets, enhanced rotary, electric spark and discharge, electric arc, water jet erosion, ultrasonic, chemical, induction, nuclear, forced flame explosive, turbine, high frequency, microwave, heating/cooling stress, electric current and several other. The most promising solutions are mentioned below: 1. Hydrothermal spallation – Thermal spallation drilling uses a large, downhole burner, much like a jet engine, to apply a high heat flux to the rock face. This drilling technology is based on thermal processes of rock spallation and fusion. 2. Chemical plasma – is based on crushing by high-speed combustion, but nitric acid as oxidizing agent instead of oxygen. 3. Erosion - most patents refer to water jet rock cutting. Different modification variants are described, e.g. utilization of cavitation, turbulent processes, combination with mechanical processes, etc. 4. Laser - during the recent decade intense research has been made into utilization of high energy laser beams for rock disintegration. Primarily conversion of military equipment is concerned. Laser energy is used for the process of thermal spallation, melting, or evaporation of rock. 5. Electric discharge - The methods utilizing electric discharge are based on long-term experience gained in other application areas. 6. Electrical plasma - is based on crushing by irradiation of plasma with high temperature up to 20 000°C 7. Direct transfer of heat - This technology is based on electrically melting rock at 1400°C; lava gravel will float to top; bore hole walls are of glass of surrounding rock. Cost decreases with depth, with no limit on depth of bore hole. Bore diameters from 1m to 10m. Recovery of energy used to melt rock. --- Friction drilling is a method of making holes in metal in which the material is pushed out of the way with the aid of heat from friction. The process is also called thermal drilling, flow drilling, form drilling, or friction stir drilling. Friction drilling is commonly used on bicycle frames, heat exchangers, and to create holes for mounting bearings. Advantages Very quick process (2 to 6 seconds) The process reshapes all material so that no material is lost. The excess material forms a sleeve that is about 3 times longer than the original thickness of the target material, which makes it possible to make very strong bolt joints in thin material. It is a clean process because no litter (particles) is produced. No access needed to back of workpiece, as with rivet nuts. Works in almost all kinds of metal. #HDVideoRidha THANKS FOR WATCHING!
