Method for Introducing a Borehole

Simple SummaryContent extracted from patent full text and abstract with AI.

The patent describes a novel method and apparatus for drilling boreholes, especially deep into the Earth's crust, using a drill head equipped with a high-powered thermal device, such as a plasma torch. Instead of relying on traditional mechanical drilling or melting the rock, this method uses intense heat to directly sublimate the rock (turning it from solid directly into gas). The gaseous rock is then cooled and transported out of the borehole, minimizing the formation of liquid rock that can damage equipment and hinder drilling progress. Sensors on the drill head monitor and regulate the process to optimize performance and prevent clogging.

Use CasesContent extracted from patent full text and abstract with AI.

• Deep geothermal energy exploration wells
• Drilling for oil and natural gas at great depths
• Scientific boreholes in high-temperature geological environments
• Mining applications where deep, narrow shafts are needed
• Construction of deep underground storage or waste disposal sites

BenefitsContent extracted from patent full text and abstract with AI.

• Enables drilling at extreme depths and high temperatures where conventional mechanical or fluid-cooled drilling fails
• Reduces risk of equipment damage due to minimized liquid rock formation and deposition
• Faster drilling rates due to avoidance of melting/solidification cycles and reduced clogging
• More precise process control through real-time monitoring and regulation of phase change
• Potentially lower maintenance costs and longer service life for drilling equipment
• Allows for boreholes with very high aspect ratios (depth to diameter)
• Produces finer, easier-to-remove material compared to traditional drilling debris

Patent Abstract

The invention relates to a method for introducing a borehole (1), in particular into the earth's crust (3), by means of a drill head (4) which is held in the borehole (1) by a drill rod (5), the drill head (4) comprising a thermal device (5) by the effect of which on the bottom (2) of the borehole (1) material (2) on the level of said bottom is dissolved from the solid phase by phase change and the dissolved material is transported away in the direction of the surface of the earth (7). The thermal device (5) is operated in such a manner that it generates such a high thermal output power that the material is predominantly sublimated during the transition from the solid phase.
