Abstract

Particularly deep boreholes (14–30 km for 300 ° C and more) are very expensive or not possible with the current technology. If 300 ° C can be reached economically anywhere, old nuclear power plants and old coal-fired power plants can continue to be used, since the steam is then generated by geothermal energy. This is because deep drilling is still carried out as it was 150 years ago: the drive is at the top, the drill bit at the bottom (control "from above"). Steel plates can be sawn by high speed water jets. A ring with numerous, generally obliquely oriented nozzles, e.g. B. every two millimeters a nozzle, with two or more meters in diameter, from which water emerges at very high pressure, causes rock to be crushed in a ring. Nozzles along radii split the resulting core into z. B. three segments that are packed by the drill and transferred to a conveyor. This travels up a few hundred meters and transfers a core segment to another conveyor system (relay principle). Driving down the conveyor takes z. B. Wall segments and equipment with. Electricity, water, data (LAN cable) etc. can be found in the borehole wall. The work is monitored by cameras etc. and carried out by manipulators / grippers. The borehole wall, conveyors, drilling rig and computer form a drilling system with which very great depths can be reached quickly without a drill string and without a drill bit.

Description

Short explanation according to paragraph 10 (actual description afterwards)

(1) Description of the Invention: Chiselless drilling system

(2) Other information

• 1. Technical field: Geology: Deep drilling technology
• 2. Prior art: See (3). Understanding: I'm a geologist myself.
• 3. Underlying problem: So far, de facto world-wide, is drilled as 150 years ago: Above is the drive, below the Bohrmeissel, in between the Bohrstrang. The control is often impossible at great depths (14 kilometers and more) ("the bore runs away"). The drilling progress is slow; high chisel wear, etc., because the entire drill diameter is crushed. The extraction of cores is extremely time-consuming (and rare), as it requires the entire drill string to be pulled and reinstalled. Bores of z. B. 20 km depth were therefore never made. They are conventionally completely uneconomical, even with large diameters, z. B. two meters and more. At high temperatures (300 degrees and more) the drill string can soften. The generation of steam at virtually any point ("drilling until it's hot enough") is currently completely impossible in economic terms. The solution: The individual functions of the drilling: Drilling, transport of the drilled material, energy supply, expansion are conceptually and mechanically completely separated. There is no longer a continuous drill string, there is no big drill bit: it is drilled by a small drilling machine, which drives autonomously at the borehole wall. The drilled cores are segmented on site (in the borehole) and packaged ready for transport (in the borehole, ie also in 10, 20 and possibly more km depth). The cores are driven up in a relay system (no interruption of transport and drilling). Expansion elements are driven in the opposite direction with the relay system down. Energy and water are transported in the borehole wall. Everything is controlled by LAN (LAN cable in the borehole wall) of computers, if necessary humans on the computer. Work (installation of the wall segments, if necessary maintenance) is camera-monitored, remotely controlled (grippers, manipulators). In this way very large depths with very large diameters can be achieved very quickly. Very fast drilling through hundreds of high-pressure nozzles from which water emerges at supersonic speed. For example, it is possible to extract hot steam economically for power stations (and also for house heating, the steam is "voluntarily" upwards without pumping). With a variation even very large depths can be achieved, for example, to replace blast furnaces by deep drilling. The invention is comparable to the antilock braking system of cars: the components existed before. The integration resulted in a completely new very useful invention.
• 4. The invention for protection is sought: The "Chiselless drilling system" as described in terms of the overall system. The components themselves, z. As high-pressure nozzles, LAN cables, packaging systems, Stafettensysteme are state of the art and in the corresponding fields, also from outside the geology, available (feasibility). The new is the drilling system as a whole for deep drilling. Also subordinated is protection sought for the same drilling system when used for tunnel boring, provided that the tunnels are produced by core drilling (a very significant difference from previous methods) and have at least a diameter of about two meters.
• 5. Industrial Applicability: Rapid drilling with large diameters up to large (14-20 and more kilometers) and very large depths. Commercial Benefits: Winning hot steam for old coal-fired power plants and old nuclear power plants (new ones too) in which water is routed down virtually anywhere and hot steam comes up, as well as steam for home heating (including neighborhoods): solving the nuclear problem (no nuclear power plants needed anymore, especially since the reserves of natural uranium, "conventional", only about 40 years are enough), solving the CO ₂ problem and of course lowering the operating costs of power plants, since no more fuel is needed .. Side aspect: Rapid drilling of tunnels when the technology is horizontal is applied.
• 6. Advantageous effects: See (5)
• 7. Execution: Purchase of components from qualified component manufacturers: z. B. nozzles from Bosch, concrete segments of precast concrete plants, pumps, motors, thermal insulation, etc. as well, Stafettensysteme of z. As manufacturers from the packaging industry, cameras, grippers, manipulators from appropriate manufacturers and integration to the new drilling system as described below. Implementation: Ordering after granting the patent. Existing power plant operators (acceptance guarantee of hot steam) and existing (old, eg decommissioned) power plant (s) will inform the customer about the specifications of the power plant (no undesirable developments). This addresses suppliers who can deliver the components with an insolvency-proof functional guarantee (in other words, so that the bank is satisfied) (ie also for 300- 350 ° C). Thus, a financing commitment is achieved, so that the suppliers can then build the components. Until the patent is granted, the system is prepared in the computer in the sense of construction drawings. If other funds arrive, the system may be built without bank financing.

problem

Deep drilling, especially coming deep wells (14-20 km and more) are very expensive with the current technology, very tedious and sometimes (especially deep holes, for example, to reach in northern Germany 300 and more degrees Celsius) so far not possible or not economical.

The achievement of 300 ° C is economically relevant: Then, if 300 ° C anywhere can be easily achieved economically, old nuclear power plants and old coal power plants can be partially reused because then the steam generated by the geothermal energy: feeding water in a closed Lowering the system, introducing steam, using a heat exchanger and using the very normal existing power plant technology - not all power plants, but quite a few. So far, this has been searched for particularly suitable locations - for example in the Oberrheingraben. However, locations such as the Upper Rhine Graben have the disadvantage that, to put it simply, geologically, there are very many tensions. It can not be ruled out that in very rare cases, boreholes will cause tensions that will lead to earthquakes (which would have occurred anyway, but some years later). For this reason too, it makes sense to drill where the power plants are - in "cold" areas (eg Northwest Germany, Scandinavia) just lower accordingly.

A cause of the technical problems lies in the fact that with oil wells and other deep wells conceptual drilling is still boring like 150 years ago: Above is the drive, down the drill bit and the entire bore is controlled "from above", thus also with regard to the mechanical " Control of the drill head "(distraction, etc.).

Costs also arise in that the rock in the borehole diameter completely, so on the whole surface of the borehole, is crushed (energy expenditure, chisel wear) and pumped up by a flushing. Then, if at a given diameter z. B. only a fraction of the rock must be crushed arises, due to the lower energy consumption, even a fraction of the cost. In addition, it goes much faster, of course - depths in northwestern Germany of 300 ° C can be reached much faster (eg in one to three weeks, later less). It can be at a power plant location z. For example, 20-30 holes are drilled so that the necessary amount of hot steam is generated for a large power plant. This means that existing investments (old nuclear power plants, old coal-fired power plants) can continue to be used cost-effectively. Important effect: If deep wells can be practically carried out "economically" up to 300 and more degrees Celsius, the well-known high-temperature areas and their geologically-related problems can be dispensed with. Where now already power plants are in operation (eg Ruhrgebiet, Hamburg, Sweden), the deep wells are drilled. The predominantly existing power plants then receive the steam via a heat exchanger, ie in the quality to which the corresponding turbines are designed.

The solution is to integrate existing technologies that are recognized as functioning, even from outside geology, in such a way that a completely new system (inventiveness) is created.

The solution is patentable comparable to the anti-lock braking system in cars: the individual elements (sensors for the rotational speed of the wheels, control of the brake pressure, etc.) were long before already available; the integration was then a completely new invention. Since so far still "the whole world" drills with deep holes with drill bits, the height of the invention is proven. Also, the fact that coal-fired power plants are currently being planned instead of converting the steam-side part to geothermal steam proves that the solution is by no means obvious to those skilled in the art.

solution

Steel plates can be sawn by high-speed water jets. For the sawing of rocks in quarries this is sometimes reported. Also, in water jets of high pressure (and high speed, eg, supersonic speed) outside the nozzles, grains (eg, quartz grains) may be fed, so that the abrading effect is enhanced.

A ring with numerous nozzles, z. B. every two millimeters a nozzle, at two or more meters diameter, from which water exits at very high pressure, causing rock is initially crushed annular. The nozzles can be mobile or solid. For fixed nozzles, the Water jets are vertical or inclined as a rule. The successive lowering of the ring and the inclination of the nozzles then causes an annular crushing of the rock. Especially in the case of fixed nozzles, two or more adjacent oblique water jets may intersect each other. Of course, the direction of the water jets can be controlled, either by moving nozzles or by a second jet or controllable deflecting in the beam.

The annular crushed rock, z. B. a few millimeters, is sucked off immediately, the ring is lowered further. Thus, according to the type of core drilling machines, only the rock ring is crushed, not the entire diameter. The extracted stone is either stored locally in a tank and later (see above) moved together with the core upwards; alternatively, it is immediately pumped upwards, be it in a tube / tube in the borehole wall or a tank higher up or straight up (the latter especially at the beginning of the bore).

In addition to the ring can (phase one: usually) radially (for example, three radii at 120 ° distance, in the manner of a "Mercedes star") be arranged more nozzles, z. For example, per radius of a few tens to a few hundred nozzles. These lower with the ring, so that three segments with height h (eg 10 meters) and 120 degrees circle share arise.

Then, when an intermediate target depth (eg, less than 5, 5, 10, or more meters) is reached, further nozzles at the bottom of the ring, e.g. B. on the type of closing device of a camera, the z. B. ten-meter-long piece of rock from the rock formation "cut off." (Also with densely arranged nozzles).

The three segments, 120 degrees and, for example, ten meters long, are then successively conveyed "packed" or "unpacked" including "partially packed" (see above).

In the case of the first 100 meters, the pieces are usually transported directly, without interruption, upwards. For deeper holes (about 100 meters to 20 or more kilometers), the pieces are conveyed up an amount (eg less than 100, 100-200 or more meters) and then transferred to another conveyor. This moves the piece of rock upwards again 100 m (less or more). After transfer to the respective higher conveyor, it then moves down again and takes the next piece of rock (the next segment of eg 10 m length, eg 2 m radius (including less than 2 m, or more than 2 m) and (eg) about 120 degrees angle).

The conveyor travels along the walls of the well, whether through metal racks, through "racks" that are part of the bore lining (eg, three, each poured into the concrete of the lining segments), whether by friction or other methods. In the case of a water- or steam-filled (gas pressure) borehole, of course, buoyancy is also conceivable as the sole or additional buoyancy means / partial drive means for the conveying devices. Such Stafettensysteme are in the field of "handling technology" "state of the art" (ie available). This is completely new in the field of drilling and deep drilling. This justifies the comparison with the anti-lock system in cars.

The conveyors are either powered by cables (for example, after every 100 m drilling progress, a 100 m long piece of cable is laid remotely, eg with plug contacts, remote-controlled systems (eg ROVs, also with grippers and cameras) in geology state of the art, or by high performance condensers (2500 F or more are prior art) or they are passively moved by the weight of the water to be transported .. Combinations of methods are also conceivable.

The water is either transported in hoses, at higher temperatures in pipes or in containers like a relay down.

In the case of containers, these can be dimensioned so that a suitably short rock segment of the respective lower conveyor is pulled upwards by the weight of the water of the respective higher conveyor. Although a drive must be present (eg for emergencies or a remote-controlled manual adjustment of the transfer), it usually requires no power (cost reduction).

In the case of hoses / pipes, z. B. every 100 m remotely controlled possibly automatic installation of a hose segment / pipe segment in the wall, hydrostatic arises even at medium depths (a few miles), a pressure that allows water to escape from the nozzle at supersonic speed. In this case, the drill (or a "ring") connects to the lower pipe segment / hose (hose in terms of hydraulic hose) and the high water outlet speed arises without energy.

In the case of water transport through containers (emptying of the respective higher container in the lower conveyor, possibly timely / simultaneous transfer of the capacitors / charging / discharging of the capacitors) correspondingly powerful pumps are required in the drill itself. pump and nozzles are prior art. The shield against heat as well.

As in many cases in low and medium depths (surface up to a few kilometers) and solid rock is not "solid throughout", but z. T. "friable" (eg tuned pitches in sandstone, ash layers in basalt, Mylonitzonen also in very deep situations, eg 60 km) can if necessary even when drilling a firm or flexible film to the respective approx Degrees segments are drawn. If the rock "cut off" at the respective end of the section, depending on the state of the art in the field of conveying and handling technology, with the cutting "ring" the "film" are pulled down to the segment, a mechanical "ring" (on the type of closure cameras) or other procedures. The extracted crushed rock of the outer ring and the individual radii, which is located after a drill section in a container (see above) is then transferred in a corresponding container of the conveyors. An empty container is taken over. Other methods in which the material is pumped from container to container or in a tube in z. B. concrete segments of the borehole wall is pumped up, are also conceivable (eg., By several powerful concrete pumps, for example in the borehole wall).

In reality, instead of alternatives, remotely controlled, one or more solutions are used in parallel / overlapping.

Drill and conveyors contain cameras, possibly also with different spectral ranges. They also contain manipulators / grippers. In this way, z. B. loose rock that has slipped out of a slide, specifically aspirated targeted crushed or transported in another slide. By "foil" is meant here all "tear-resistant flexible". They can of course be metals. Instead of "foils" also solid bodies (metal "cylinder", ceramic "cylinder") of about 120 degrees arc segment can be used. The restriction to z. B. about 120 degrees has the consequence that up and down moving loads (rock segments, water, tools (eg new nozzles), quartz grains) can easily pass each other in the transfer of a conveyor to the next. The preparation of such conveyors (stafettenartige transfer, even several components, including cameras and grippers) is in the field of handling technology possible (prior art, technical feasibility). The use in the borehole (replacement of eg drill string and mud, invention height) is completely new.

It can also be built about 1000 m in the borehole wall recesses (same technique as drilling). Upward-moving cores can then pass unsegmented, since materials traveling downwards (water, wall segments) are temporarily stored in the recess. This can be obtained from the field of "handling technology". In deep wells this is completely new. The "recesses" then get a shape that is adapted to the rock pressure. In the upper part of the hole that should be almost certainly feasible. In the lower part of the hole, this must be handled case-specifically.

Then, when supercritical conditions are reached, ie depths with temperatures at which water is no longer liquefied by pressure, other liquids can be used instead of water. It is also possible to add substances to the water (including the other liquids) that shift the boiling point upwards. This is state of the art. So even very high temperatures can be achieved - currently expected to about 600 ° C. Cameras, metal cylinders instead of foils, possibly ceramic cylinders, nozzles must be well insulated in high-temperature conditions (above approx. 350 ° C) or additionally actively cooled. This is feasible because the mechanical forces are low.

The borehole itself (the borehole wall) is lined by segments of approximately 120 ° arc remotely controlled (including semi-automatic and / or automatic). In these linings, for example concrete segments, racks (for example also made of concrete) may be where the conveyors and the drill drive down and up. Pipes can be embedded in these segments (for guiding the water and any extracted cuttings of the ring (s)). The same applies to power supply lines, data cables, antenna cables (for controlling the conveyors and the drilling rig, which bridges the "last meter" between the device and the wall, eg via WLAN, flexible cable is also possible). Also, recesses for cables, each z. B. be installed remotely controlled after such a section every hundred meters (installation with devices that are attached to the conveyors and, for example, supported by cameras, are installed by a computer controlled); this is state of the art in parts of geology (eg offshore). In the case of the concrete segments, temperature resistance exists up to high temperature ranges. Other materials (ceramics, eg for very high temperatures), metals (for medium temperatures), and z. As plastics (for low temperatures) can be used.

Is the planned final depth for z. 350 ° C (in North-West Germany, this may well be 20 km to replace the nuclear part of nuclear power plants), pipe segments for water (down) and hot steam (up) are installed remotely in the well. Is used for lighting (and for the cameras) not only normal visible light but z. B. polarized light (against scattering by drops of water / "steam drops"), active infrared lighting (also possibly polarized), short-wave electromagnetic waves ("radar") u. a. m. Particles or drops in the borehole (if filled with steam, eg from groundwater dripping from above) are not a problem. Because all or many tasks are performed remotely (including semi-automatically and / or automatically), the high personnel costs of deep drilling are significantly reduced: fewer salaries, less staff, but also less surcharges (eg daily allowances) and less associated costs ( eg residential containers).

The top of the steam is then passed through a heat exchanger, so that the power plant gets conventional, unpolluted steam. The steam used can then either continue to be used for domestic heating (more heat exchanger) and then significantly cooled, z. B. as water, are directed down or directed directly down.

Care is taken that drilled in predominantly tectonically quiet areas (ie not in the Upper Rhine Graben) and in isolated floes (ie in blocks that are surrounded by disturbances, but so that hardly one pierced) can not Doubts regarding the triggering of already existing voltages ("earthquakes") arise.

Of course, further deflected holes are also possible by drilling. The disadvantage here is that the distractions have to be made very early (eg at a depth of 3-5 km), otherwise the load will deform the deflected borehole (rock hardly transmits tensile stresses).

Since this drilling process is very fast (one to several kilometers per day are possible, bottleneck will be the conveyor technology), only vertical holes are recommended.

The racks in the borehole walls ensure that the tubes for the steam can also be serviced remotely. Large diameter, z. B. four meters, are hereby no problem.

Also tunnels can be drilled. So far, even in the high-end sector (machines from Herrenknecht), the entire surface is always crushed. If only one ring in segments of z. B. 120 degrees drilled and the individual segments "backwards" remotely controlled (including semi-automatic, fully automatic) pulled out, it goes faster.

This procedure is also suitable for questions concerning the measurement of earthquakes and their conditions (equipping the seismogenic zone with instruments). The seismogenic zone (eg, off Japan) is so deep that it is warm enough that loose rock could change into hard rock. The seismogenic zone is also so "cold" (eg, about 600 ° C) that the rock is not yet plastic (ie solid), so that earthquakes can occur at all.

With this method, even if special costs are required for the development of the borehole wall, even these extreme depths can be achieved.

Claims (1)

An essential aspect of the chisel-free drilling system is the integration of existing individual components, so that something completely new arises. The claims thus do not relate to the individual components themselves (nozzles that emit liquid at high pressure have been the state of the art for many years, eg injection nozzles in cars) but, in the manner of antilock braking systems for cars, to integration an overall system that enables particularly fast and particularly deep drilling economically. Devices for "short bores" on the surface, where humans are directly in the vicinity of the drilling rig (eg for concrete removal or cutting machines in quarries) are explicitly not covered by the claims. The claims relate to drilling systems for particularly deep holes (one kilometer to 14 kilometers and more), which are characterized, inter alia, by the following: Claim 1: System Component One: Drill The drill is characterized by: One or more fixed or movable rings with numerous nozzles, z. B. every two millimeters, smaller or larger distances of the nozzles wherein the / the rings in about the borehole diameter outside (at the edge) include. The rings themselves may be constant or consist of variable segments that are controlled (eg, rotated) and / or z. B. can be retracted inward (eg., For maintenance purposes in the borehole). In addition, if necessary, alternatively (eg at very high temperatures, eg but not only above 400 ° C), in addition to the nozzles, partially or completely alternative to the nozzles on the rings small movable chisel z. B. ceramic and / or small movable drill z. But not only ceramic. The other functionality (no drill string, no removal and installation of the drill string needed when pulling a core) remains as described in the patent (including the demarcation to existing methods). This sentence ("possibly also ....") serves primarily to formulate the claims so that future operations are possible at high and very high temperatures, ie "the drilling system as described" but individual components adapted to the temperatures ( for example, between 400 (or less) and 1200 ° C or more, hence the mention of ceramics). The drilling of a ring, the cutting of the rock formation, if necessary, the segmentation, the "packing", then z. In a ceramic container, start-up, etc. is identified as the standard application drilling system using "water" (as described below). Applications in which the ring is approximately conformed to standard technology, but optionally, e.g. B. has one or more small drills and / or small chisel are also covered by the claim. This is to systems that for legal reasons z. B. with a single (or more) small chisels (also pounding) are equipped / drills, formally in fact "for decoration", in fact to circumvent the patent, by the claim with. In operation, water, other liquids, mixtures (of, for example, liquid (s) and / or, gas (s) and / or solid (s)) and / or solutions (eg water with substances that increase the boiling point) emerge from the nozzles ) and / or combinations suitable for the purpose (including suspensions / emulsions) at very high speed. The exiting agent, even if it is not itself water, but a "different liquid, solution, emulsion, etc." as explained above, is hereinafter referred to as "water". This water ("water" in the above sense), in which, if necessary, after emerging from the nozzles (theoretically also before emerging from the nozzles) solid (eg., Quartz grains, corundum and others), z. B. "suspension" can be fed, occurs at very high speed, including possibly supersonic speed, from the nozzles, so that the rock, which is "geometrically before" the nozzles (meaning: approximately in the water outlet direction), is crushed. The claims relate to rings (ie both closed, semi-open, open including mixed forms), which have at least half a meter in diameter in the drilling operation (in the sense of rock crushing). Arrays of smaller rings are also covered by the claims. The claims relate to rings of any solid or variable simple or complex form, so z. Circles, ellipses, squares, rectangles, any polygons, circles with polygonal extensions (eg, for recesses for cables), or even completely arbitrary shapes (eg, state emblems). The claims also relate to rings that themselves in the form of their shape, eg. B. (but not only) depth-dependent change: z. B. surface near circular, then intentionally z above a certain depth. B. elliptical. The drill is characterized in that, as a rule, the core is divided by three, but also by fewer or more radii, which are likewise densely populated with nozzles (as a rule, every 1-2 or more millimeters a nozzle) into a corresponding number (at three radii, three segments) is divided. Illustrative: In the case of three radii a 120 degrees, they have approximately the arrangement of a "Mercedes star" (outer ring plus radii). This arrangement with a core (without segments), with a core having two, three, four or more segments, will be referred to as "three segments" hereinafter. Arrangements in which the ring (s) and / or the "radii" are equipped with only a few or a nozzle (for example, to circumvent the patent) are also covered by the claim. Drilling systems in which the radii are drilled ("sawn") other than "water" are also covered by the claim, as long as the "drilling" / "sawing" of the radii is part of a deep hole drilling system as described. For the rings, this applies analogously, including the application of combinations of methods (conceivable: piezoelectrically generated vibrations, if possible: cost-effective mechanical separation but maintaining the arrangement: separated cores / core segments, which are then raised up / rear and so on in that very large depths, for example (at least one of the two conditions) of 200-350 ° C or more than 10 km, can be reached). Important within the meaning of the claims is the use as part of a drilling system for deep wells / tunnel bores (in the sense defined below). The drill is characterized in that upon reaching a temporary intermediate depth, z. For example, all less than two, every two to five, every five, every five to ten meters, or all "more than ten feet," the core (the three segments) below (in tunnel bores analogous: forward) is severed from aggregate. This, like the drilling itself, can be done by water. Other separation methods are also conceivable (eg, piezoelectrically generated vibrations, mechanical or combinations of several). As a rule, the shutter-type separation mechanism is implemented by cameras (a ring that closes, eg, equipped with nozzles). Other mechanisms, e.g. B. Control of the water outlet of Nozzles of the outer ring, a part of the outer ring (which then, for example, "pulls off" a portion of the surface from outside to inside, followed by a mechanical device that keeps the cut stone at a distance from the rest of the rock formation so that it does not down "falls") are also conceivable. Irregular separation mechanisms, e.g. B. those that break the rock into small pieces are also covered by the claims - even if they do not appear appropriate due to the higher energy consumption. Important for the claim is that a dormant or predominantly dormant core (in contrast to conventional "rotary" cores) of large diameter (eg half a meter to several meters) is controlled or predominantly controlled by the aggregate is separated so that it completely or in parts (eg segments) can be "wrapped" / "packed" for transport (including envelope, container, etc.). This component (also part of the invention) is a component of several essential: In conventional core drilling for each core of the entire drill string must be pulled up (= removed and reinstalled). There is no drill string here: The cores are (in whole or in segments) from the drill (or the conveyor above him) "packed ready for transport" and z. B. transported by other means (eg., Conveyor / e) upwards. The absence of the drill string for achieving the functionality (drill string in the sense of oil wells) is one of several key features of the chisel-free drilling system: A time-consuming and costly removal and installation by pulling the drill string is omitted here. The drill is characterized by the fact that usually during drilling and during and after the separation of the core (the three segments) from the aggregate around the core (around each segment) a "shell" is pulled. This shell may be flexible (eg a tear-resistant foil), be a grid and / or be strong. The shell can (but does not have to) z. As plastic (at lower temperatures), metal, ceramic or other material or more materials. It is important that it is pulled around the core (including "the three segments" in the above sense) in such a way that the "three segments" can be conveyed in a controlled manner upwards, ie in such a way that z. For example, in normal operation, pieces will not fall off the segments, disintegrating ("crumbling") the segments thereby leaving the sheath / container, etc. The "machine wrapping of material in transport cases / containers" is prior art in many industries , so available. What is new is that this technology is used as a system component in drilling - comparable to the components of anti-lock braking systems in cars. The drilling rig is characterized in that it either transports the retained core (in one piece or in segments) either upright (then the core can be carried inexpensively even without dividing into three segments) or to a conveyor piece by piece or in part (each Segment individually), which passes when transferring z. B. located above the drill. The drill is characterized in that it carries the necessary water (in the sense of the claims) and / or the energy (usually electricity) for drilling itself (water in a tank, electricity in a storage, eg large capacitor, battery and / or further memory) as well as from the conveyor (properties of the component "conveyor" below) enriched above him receives as well as / for example from the borehole wall relates (system component "borehole wall" below). The drilling rig is characterized by having means for monitoring, control and, on a case-by-case basis, equipment for manipulating rock, components (including drill, eg for repair), conveyor, borehole wall and others. These are, for example: illumination devices (normal and polarized), including various spectral ranges, including radar, visible light, infrared, corresponding cameras (fixed and controllable), microphones, grippers, remote-controlled tools (also for repair in the borehole, for freeing stuck pieces of rock for, if necessary, loosening, the shell to be pulled around the core segments, etc.). This includes semi-automatic systems as well as fully automatic and explicitly manually controlled (each movement controlled by an operator). As a rule, the drill is controlled by LAN. This includes partial or complete WLAN (for example, to an antenna cable as part of the equipment of the borehole wall). A control by explicit signals (ie without LAN, but conventional switches and / or cables) is also covered by the claim. The claims do not refer to "deep hole drilling systems" (including tunnel bores) to the individual components such as "grippers", "cameras", "screws" etc. (the individual components are "prior art"). Again, the components themselves, z. B. controlled by LAN or WLAN, are individually state of the art. The new is the integration to a drilling system, comparable to the components of anti-lock braking systems in cars. Delimitation: The claim does not apply to machines for piercing concrete ("concrete removal") - except, of course, as an additional function z. As the drill, a conveyor or other device of the system for use in deep wells, z. B. for drilling holes for brackets in z. B. the concrete segments, z. B. to install something in the borehole. Existing machines for "drilling through concrete" are characterized by the fact that in the immediate vicinity of the actual drilling site (eg a wall), people can remain or remain largely unprotected (including normal construction site protective clothing) in normal operation. This (unprotected stopping of people near the drill in normal operation) is usually not possible in deep wells (except in pressure chambers, also with oxygen supply, deep sea submarines comparable). The claims also apply only to systems in which humans are usually more than 200 meters away from the actual drill rig (apart from the start). However, these include systems that are drilled approximately horizontally using very large diameters (tunnel boring without crushing the rock over almost the entire surface, ie in the form of core drillings). The drilling rig is characterized in that it can either carry the drilled cores (including the "three segments") upright itself, or transfer them to a conveyor, or alternatively can do both. (For example, drive yourself up during the first 100-200 meters, passing below 200 meters to a conveyor). The drilling rig is characterized by having either the appropriate aggregates to achieve the water pressure necessary for drilling itself and / or appropriate water of suitable (eg, high or normal) pressure from the borehole wall (including from the space above it, for Example of the conveyor above it) and / or can optionally apply both methods (eg, depending on the depth). The drill is characterized in that it can remove the drilled rock from the actual drilling area. As a rule, this will be suction. The removed ("extracted") rock is selectively stored in a tank and / or container (eg, open), for example, the drill, or carried into the wellbore wall (eg, through a hose / tube into another) Pipe in the borehole wall). The drill is characterized in that after drilling of z. B. one or more (or less) millimeter rock (or during drilling itself) moves down in accordance with controlled. This happens either in sections (one millimeter each and then a break) or continuously or at different speeds. As a rule, the drilling progress is monitored regionally (eg with the individual nozzles) (be it mechanically, or by other methods). The results of the monitoring flow into the control (remote manual, semi-automatic, fully automatic) of the nozzles (direction, water pressure, etc.) and / or the ancestor of the drill. In this way, heterogeneities in the rock are compensated. In part, optional small movable chisel and / or small drills (as in DIY drills) can be used between the nozzles to z. B. to remove any remaining small "pillars" between the nozzles. When drilling radiolarite, individual fronts of mobilized and later solidified "silicic acid" (in the geological sense), it may be that individual pillars remain between the nozzles - hence additional optional extras. The drilling rig is characterized in that it optionally has means (typically additional nozzles with associated components) for controllably drilling holes and / or recesses laterally in the wellbore wall. The holes serve to lock, for example, segments of the later borehole wall (including holes for rock anchors of different lengths, special or standard "dowels", extensions of the segments of the borehole wall, etc.). The recesses serve that, if it is expedient in each case, the respective downwardly moving conveyor in the recess material can settle (for example, a water tank, a large capacitor but also segments of the system component "borehole wall"), a core at a stretch ( without segments), returns to the top, gives the lower conveyor opportunity to pick up the things parked in the recess and drive back down. This optional feature is optionally available on the lowest conveyor and / or optionally on other or all conveyors. The suitability (replacement of tanks / condensers vs. direct exchange of liquid / electric charge vs. transport in the borehole wall) is assessed on a case-by-case basis. For example, if quartz grains are added to the water during drilling, it may be that these quartz grains must travel down a container. This container can then be temporarily deposited in the recess. Alternatively, of course, the cores may be segmented so that downwardly moving containers and upwardly moving core segments may pass one another. The drill is characterized by the fact that it usually goes up and down the borehole wall can. As a rule, it does not depend on a cable from the earth's surface or on a drill string. It drives actively controlled. A hanging on a cable (for example, to the power supply or as a connected rescue cable, which can be pulled up in the event of system failure, possibly also from a recovery equipment, including the often mentioned manipulators / grippers), although it is inappropriate (eg B. 14-20 km cable generate costs) is included in the claim. The driving is usually done by a plurality of gears on racks, in the borehole wall, z. B. as part of the wall segments (see below), are embedded. Instead of the gears, caterpillars, friction from pressure on the borehole wall (eg even without wall segments or repairs), buoyancy (if the borehole is filled, eg with water or at great depths and / or high pressures) also with steam (then with appropriate sealing) or other driving aids (including slip aids, buoyancy aids, hovering aids or combinations of several) may be used. For canted segments of the borehole wall (eg, due to "geological movements") do not present a problem, several drive components are installed (gears, caterpillars, each several gears in a lane, which, when reaching a hole in the borehole wall by individual movements, fully automatic, semi-automatic or remote-controlled, which can overcome the fault, etc.). Illustrative example (analogy): Imagine that with a roller skate for in-line skating, the roller shoe raises and / or lowers the wheels when needed individually (ie one of four), so that z. B. stones on the road without intervention of the skater can be run over. The drill is characterized in that all components, depending on the depth of use and conditions optional against z. B. negative effects of temperature and / or moisture shielded ("isolated") are. Further shields of the drill / of the conveyor s / e, z. B. Netzte / plates against falling rock are also included in the claim. This can be a passive shield (protective tank, temperature resistant materials). This can, in particular at very high temperatures (eg 300-600 ° C., possibly even more), also be an active cooling, be it by a circulating, warming (including evaporating) liquid or another cooling device. The mentioned at the beginning of this chapter tools (remotely controllable tools, grippers, etc.) serve to occur in the borehole itself incidents, eg. For example, canted rock pieces to be handled (eg, removed), usefulness of the patent that the drill does not have to be brought to the surface. Claim 2: system component two: driving device The drilling device actively moves up and down at a device in the borehole. This device is characterized in that it has, for example, wheels (eg gears running on "racks"). These racks may be explicitly incorporated into the borehole wall (metal racks) or implicitly cast (eg, for concrete segments for cost reasons and for temperature resistance). In the case of racks are usually at least three such racks, arranged at approximately 120 degrees angle to each other. The claim also applies to drills that do not use racks (eg with caterpillars) which hold themselves by friction (pressure) on the walls, with fewer or more than three racks (in the sense of "guiding devices of a general nature") or even, fully or partially floating or floating (by vapor pressure at deep holes). The phrase "guide means general type" means: "racks, rods, possibly flat, curved, with additional grooves, additional grooves, etc., which are such that one or more driving device, one or more conveyors can hold on so that the Purpose of the patent (deep drilling, possibly tunnel bores with at least two meters in diameter, executed as core holes) is achieved, so that they z. B. can move up and down, with a correspondingly low weights or as an implementation of redundancy even on a single rack can hold without crashing etc. Legal Note: The patent is written by a geologist, not an engineer. It means facilities that "act like racks, z. B. in the sense described above ". The claim also applies to combinations of driving possibilities. The driving device can therefore be both part of the drilling device and part of the borehole wall as well as part of any liquid / vapor in the borehole as well as - usually - a combination of both (drill plus borehole wall, eg gears plus racks) represent , The additional devices (eg optionally individually controllable gears / wheels) mentioned with system component one (drilling device) also refer to the driving device and to system component three, the conveying device. The racks themselves are "state of the art". The claim relates to drilling systems that use racks (in the sense described) to the previously unachievable purpose of the patent, z. B. very deep holes to achieve. The drill is characterized by being able to travel downwardly a limited distance beyond the end of the racks drill (eg the mentioned core length of 5-10, more or less meters). The drilling device for the drilling rig is thus characterized by controlling the drilling device, for example by suitable guide means (eg by continuously measuring the distance in front of the nozzles, removing individual "micropumps" of the rock, for example by one or more controlled oblique jets of water or small "chisels"("chisels", between the jets), small drills ("drill bits", dentist drill to do-it-yourself drills, between the jets) downwards.This can happen in which the driving device in an intermediate End depth stops and then the actual drill, for example, on telescopically arranged holding devices (eg but not only telescopic rails) controlled downward leaves.The mentioned cameras, manipulators / grippers are also used, if, for example, the drill slips out of one of the racks (eg does not stop in time), remotely "scrape it" again ng: It is important that the drill is actively controllable without being passively suspended from a drill string (including mechanically in normal operation on a cable in the sense of a hook load). Cables for power supply or data cables (eg LAN) are not covered (= LAN cables may occur). Rescue cables, which can be retrieved in the event of a system failure or attached to a conveyor for rescue, may also be optional but are not a component in normal operation. The claims relate only to drilling systems for greater depths (at least two hundred meters depth, usually 10, 14, 20 or more kilometers), in the case of tunnel bores only to core holes with at least about two meters in diameter. Claim 3: System Component Three: Conveyor The drilled and optionally packaged cores / core segments are transferred from the drill to a conveyor, which also actively moves up and down on the borehole wall. This conveyor is characterized in that it can actively (remotely, semi-automatically or automatically) drive the borehole walls in the sense mentioned above, can hold the core (s), occasionally material to be transported (eg water, cables, pipes, tanks, Capacitors, segments of the borehole wall and other) can transport, both case by case to another conveyor up and / or handed down can ("relay-like") and the necessary grippers / manipulators and monitoring systems (eg cameras) has. Optionally, the conveyor may also include other grippers / manipulators / cameras, etc., for. For example, to assemble segments of the borehole wall, to perform maintenance, to rescue equipment (eg a clamped other conveyor or even the rig), among other things, there may be an upwardly moving core segment downwards as it passes from a lower to an upper conveyor Moving things (eg wall segments) are passed (the rule). It may occasionally, z. B. at shallower depths (a few miles), the downwardly moving material are deposited in a recess, so that each upwardly moving core can be handed over unsegmented. At least the lowermost conveyor and / or the drill rig (at the top) is additionally equipped with means for installing the wall segments and other necessary items (eg manipulators, grippers, cameras (polarized, unpolarized, active infrared, radar and other). The optional equipment, optional equipment and equipment specified on the Conveyor and elsewhere are also applicable to the system component "Conveyor." The optional features of the drill (see above), such as individually controllable wheels, also apply to the conveyor (s) The transfer to the respective higher conveyor as part of the drilling system causes each conveyor to travel up and down only a short distance (for example, for three core segments three to one hundred to two hundred meters up and down) (see below) Length of the core (referred to as 5 10 meters for example) speed of the conveying devices, rate of incorporation of the wall segments are matched in a rule makes sense to one another so that a quasi-continuous operation may occur. The intervals of each relay can also be larger or smaller than the mentioned 100-200 meters. Related side aspect: The operation, z. B. with radio beacons to settle the cores on the earth's surface, remote controlled and / or automatic devices (eg., Forklift) on the earth's surface for settling the cores and / or recording the concrete segments can optionally be controlled remotely, z. B. by one or more people on the computer), semi-automatic or fully automatic (eg., At night). A "fully automated warehouse" is "state of the art". These methods are optionally used as part of the drilling system on a case by case basis. In the field of "handling technology" such systems are available (eg by experts in the industry handling technology). As part of a drilling system for deep wells they are new. Demarcation: A "classic" core tube ("core-barrel"), z. B. as part of a drill string is not covered by the claim. A "classic" core tube may, for. For example, do not yourself active up and down (it depends on a drill string), the core not other core tubes passed, etc. Claim 4: System component four: Energy supply The drilling system (drill, driving, conveyor, possibly pumps, tank / s, remote-controlled Tools, cameras, etc.) is operated and controlled substantially electrically. Other methods are also conceivable and are also covered by the claim but do not appear appropriate. The current is supplied either by cables (including rails) in the segments of the borehole wall, on the borehole wall (outside, eg on the "air side" (as opposed to the rock side) of the segments, eg but not only in one Cable duct of the wall segments) or by exchangeable electricity storage, such as large capacitors, batteries, etc. The term "air side" is understood throughout the patent as a distinction to the rock side, so in water completely or partially filled holes accordingly as the water side. Claim 5: System Component Five: Water Supply The mentioned "water" (liquids and the like in the above sense) is the drill "topped" either by means of conveyors from above (transfer of a tank, possibly only transfer of the liquid, eg tank-like emptying of tanks) or the drill receives the necessary water from the borehole wall (the last meters then in a solid or flexible tube, hose including hydraulic hose) u. At the start of the drilling (in the sense of near-surface), the water can also be obtained by the drill from the earth's surface (eg in a tank, through a hose, etc.). Claim 6: System Component Six: Transporting the Cuttings The aggregates separated from the aggregate by the water are extracted immediately after separation in the immediate vicinity of the nozzles, with or without water involved. These extracted rocks (including clay minerals, "sludge") are either pumped into a tank of the drill or a z. B. flexible tube / a flexible hose (including hydraulic hose) pressed into the borehole wall. Pumping into a tank located in a conveyor (eg above the drilling rig) is also conceivable. The tank (s) (including drill, conveyor / s) may have components for separating the water so that the water can be fully or partially reused. Also, the grains may be carried up with water in the tanks or in the borehole wall. This also applies to combinations of methods, eg. B. the upper kilometer in the borehole wall (by, for example, concrete pumps (in the sense of the name of the equipment in the trade, meaning the actual pumps, not the trucks on which they are currently mounted mostly) at appropriate intervals) and the lower kilometer in Driven tanks. Claim 7: System Component Seven: Borehole Wall The borehole wall is characterized in that it is part of the drilling system. It allows the drill and / or conveyors to ascend and descend. Depending on the conditions, it transports energy (eg through power cables), water and data (LAN cable) be it in it, be it on it. The borehole wall is characterized by the following components / properties: As a rule, the borehole wall consists of segments (for example concrete segments) which, for B. one third (or more or less, eg, a quarter) of the borehole circumference cover all or part and optionally contain controllable openings optionally (eg flaps). These segments are in many cases initially part of a circle. But they can also have other shapes (ellipses, squares, polygonal shapes, etc.). As a rule, each segment (eg concrete segment) has one or more toothed racks (for example made of concrete) mounted or cast in or the concrete is initially shaped so that it acts as a toothed rack. The term rack also refers to "multi-sided racks", ie those that z. B. on two or three sides rack-like depressions have (see explanation in system component two, "driving"). Other surface designs (protrusions / recesses) are included. Important is the expediency for raising and lowering the conveyors / drilling rig. The racks can also be retrofitted (eg remotely controlled from metal). Other devices in which the drill (for example, with the driving device) and / or the conveyors hold, are also covered by the claim. The segments may be of various suitable materials (eg, metal, at medium temperatures), plastic (at low temperatures), or other materials. Concrete and / or ceramics appear to be the most convenient because of their resistance to corrosion and / or heat. The segments become on the borehole wall in the sense of the rock (including loose rock), whether by the drill itself (above-mentioned manipulators / gripper) be it for example by the lowest conveying device (there manipulators / grippers) or further conveying devices at / in the borehole wall suitably fastened (eg by extensions, eg of concrete, which fit into recesses of the borehole wall, anchors (in the sense of small, medium or large rock anchors), "dowels", cement, etc.) The installation is remotely controlled, be it remotely controlled manually (eg monitored by cameras), remote-controlled semi-automatic, remote-controlled fully automatic, fully automatic and / or combinations thereof (eg temporally changing) or even locally "remotely controlled" (control device for example in the drilling device). It is important (explanation of the term "remotely controlled" that no staff needs to be in the borehole (and usually can not be due to the temperature, for example), for example, to drill a hole, enter cement, hold a segment etc. This is done by the mentioned manipulators / grippers, which is a state of the art in other parts of geology, for example in the maintenance of pipelines Depending on the task, the segments can have passages in vertical (including predominantly vertical, oblique , subhorizontal, partially horizontal, convoluted) direction in which then tubes / hoses (eg for water) and / or cables (power cables, data cables) can be installed by the manipulators, for example. One of a plurality of wellbore perimeters) may be particularly thick and may then accommodate, for example, the "air side" (as opposed to the rock face) of the wellbore (e.g. by recesses, vividly: how vertical / subvertical cable ducts act) for the installation of pipes, cables etc. The installation of z. B. 100 meters of pipe and other things (power cable, data cable) can then be the last operation for a section of for example 100 meters. The drill then closes its power cable (if any) its water inlet and outlet (in the sense of the above tanks) each z. B. 100 meters further down, and drills the next, for example, 100 meters. The term "cement" (expediency of the patent) refers to "suitable cements of all kinds" / "suitable concrete mixtures of all kinds", ie also z. For example (eg in the case of a water-filled well) cements that are placed under water and harden under water (in the sense of cements in oil wells). Wall segments (with racks) are promptly (remotely controlled including semi-automatic and / or fully automatic) enriched (and installed), pipes and cables always after a larger section (eg 100 meters). The sections from which pipes are installed may also be longer or shorter, for example 20 m, 200 m, 500 m 1 km or more or less. The need to install wall segments, pipes and cables explains the low drilling progress from less than one to several kilometers per day. With the high number of jets that emit water at very high speed, drilling steps (core holes (!)) Are actually one meter in 10-60 seconds (one meter per minute), ie 1.4 to 8.6 kilometers per day (!) equivalent to about 24 kilometers in three days possible. The interruptions (realism) to the installation of the segments usually cause lower Bohrfortschritte. Depending on the task (actual purpose of the well), the segments on the "air side" of the well (as opposed to "rock face") include mounts / recesses for borehole equipment to be installed (eg, water and hot water pipes, cameras, and microphones for monitoring of the borehole, etc.). The equipment can then be serviced remotely due to the racks. The conveyors or individual conveyors or special conveyors then build the equipment (eg pipes) remotely controlled, semi-automatic, fully automatic - either z. B. from bottom to top, or, by smaller conveyors, the z. B. convey no core segments but tubes and tools (lighter and / or smaller) in other orders. Small conveyors and / or conveyors with low loads can be z. B. on a single rack, if this has appropriate grooves / projections / grooves (more specification so, system component two, driving device). The racks are designed appropriately, so that z. As a smaller conveyor / driving device without high payload (no rock core / segment, but eg only tools and spare parts, eg pipes) can also hold on a single rack, for example, because they are each designed that they z. B. by gears or other wheels or other holding mechanisms / driving mechanisms can be included from multiple sides. As part of a drilling system, this is new. This explains the invention height: The individual segments, for example concrete segments with z. B. cast racks, optional passages for pipes / cables, optional recesses for pipes / cables can z. B. from precast concrete plants. As a single element, the concrete segments are "state of the art". This proves that this concept can be implemented. The new is the integration to a drilling system, with the very big depths can be achieved economically. It corresponds to the integration of existing components in the antilock brake system of cars. The fact that the replacement of coal-fired power plants by new coal-fired power plants and the total dismantling of nuclear power plants (including the non-nuclear part) is being considered, instead of obtaining the steam in corresponding large quantities by geothermal energy, shows the inventiveness (such great depths of qualified Drilling companies are currently not economically viable in terms of routine steam generation). Additive for extremely high temperatures, eg. Eg to reach ranges between 350-500-1200 or more ° C. Claim 8: Optional further properties for very high temperatures For high temperatures (350-600 ° C) and / or very high temperatures (600-1200 or more ° C ), the wall segments can be made of a suitable refractory material, so that in case of appropriate applications, little or no heat penetrates into the well and / or the penetrating heat can be dissipated quickly. Also, then, the holes may optionally have horizontal dividers (eg, heat-resistant ceramic doors) so that heat from the bottom of the hole does not or only controllably penetrate into the entire bore. At above temperatures, the "drilling" by the manipulators / grippers / as part of the ring occurring small chisels (eg hammering), occasionally occurring as part of the ring small drills (order of magnitude: drills from home improvement drills but extremely heat resistant, z B. but not only ceramic). The system works as described in the patent. At very high temperatures, where liquids are hardly ideal, the numerous small chisels / numerous small drills mentioned above are used on the ring in addition to and / or instead of the nozzles. Compared to a drill with a chisel on a drill string, this therefore continues to be a chisel-free drill, since a drill bit in the sense of today's drill bit of oil wells does not occur (compact formulated as a rule, based on the Bohrlossdurchmesser, large chisel on a drill string which is rotated by the drill string). Of course, at very high temperatures, the drilling rate will be very low (small chisels / small drills instead of water). However, there are applications that are all about "drilling" such areas, even if it is slow or very slow in the high temperature range. Limitation: Previous drilling systems have a single drill bit attached to a drill string. In the case of previous core tubes, numerous passive elements (eg diamonds) are present below. Also, the core tube hangs on a drill string. In the system of the patent, the nozzles are then wholly or partially replaced by numerous small, actively moving bits (eg, hammering) or numerous small actively moving drills, possibly individually controlled. The hot rock is thus handled remotely, semi-automatically or fully automatically. As described above, a segmented core is formed as a rule. This core is also cut as described using the above extension of the aggregate and transport ready, possibly "packed" in segments, eg. B. in "cylinder" made of temperature-resistant ceramic (including "cylinder type of core segment of 120 ° arc). If the components for a high-temperature drill are made of appropriate materials (eg ceramic and / or using ceramic), such application is possible and thus covered by the patent. Vehicles and conveyors are then adjusted accordingly. This is z. B. relevant for scientific applications, in which z. For example, the properties of deep crustal beds should be investigated (eg, in principle, parts of the lower crust or even of the upper mantle with correspondingly near-surface occurrence or even in isolated cases in "normal" deep occurrence). In principle, active magma chambers can be drilled in this way. In the application, the known PT diagrams and the altered rock behavior at z. B. Pressure change (local pressure relief) to consider. With appropriate adjustments for high and very high temperatures, the knowledge of professionals from z. B. Mineralogy to consult. This (the inclusion of knowledge from mineralogy) applies mutatis mutandis to the design of the conveyors, the wall segments, the manipulators / grippers, etc., so z. As the consideration of recrystallizations from certain temperatures. Economically, this is relevant for applications where a certain target temperature is to be achieved cost-effectively. Claim 9: Optional addition to the borehole wall (claim seven). The system components "borehole wall", "conveying device", "driving device" and possibly "drilling device" optionally have an extension, which is characterized by: Conveyor, driving equipment and drill are equipped so that they can drive up and down the borehole wall so that they can pass each other at the meeting points, z. B. on the type of meeting point in funicular railways. This means that then cores can be promoted unsegmented. The encounter point is with suitable rock then an extension of the borehole diameter (simplified formulated: a larger diameter, in a drilling with controllable nozzles from which emerges as above water as described above, this is technically no problem). The "racks" (as described above) are such that the upwardly moving conveyor deviates to the side; the downhill diverges to the other side and passes down. This can be realized, for example, by further racks: In a case with three racks for the upwardly moving heavy conveyor (with core), z. B. two (or one or more than two) further racks the descending light conveyor (empty weight plus concrete segments, possibly water, electricity, etc.) lead to the uphill passing. In addition, the downwardly moving conveyor may be partially folded (eg in stacked concrete segments) so that the extension of the escape point does not need to be so large. The downwardly moving conveyor can also hold on one side only on two or a rack etc. The claim relates to components for a deep drilling system. For funicular railways, such facilities have been state of the art for many decades. This is new for deep wells. In the upper part of the bore, this is feasible in many cases, especially for very stable rocks (eg granite). In the lower part of the hole, this is decided case by case. The claims (avoidance capability) apply analogously to the system component driving equipment and drilling rig. Economic relevance: Less energy, no need to cut the cores (at least in the upper part), faster "drilling progress", as the promotion is faster due to less driving movements.
