- Drilling in a body of water can easily with a drill from a floating platform, especially a ship, a pontoon or a swimming barge.
- a floating platform With the floating platform, undesirable movements of the drilling tool relative to the wellbore may occur, which is problematic for a safe and accurate implementation of the wellbore.
- the movements can occur parallel and / or perpendicular to the borehole axis.
- the movements of a floating platform which may be subject to wave motion and / or tidal movements on a body of water, may be a few decimeters to a few meters.
- a Kelly drilling procedure is often used to create a well in the waterbed.
- a drilling rig with a Kelly bar is used, which is a telescopic boring bar.
- the Kelly bar, on which a drilling tool is located in a lower area, can compensate for changes in length during drilling.
- Floating use of the Kelly drilling method to drill in a body of water from a floating platform can also cause wave motion problems if the axial displaceability is blocked.
- a high bending stress of the Kelly rod can occur in drilling operation.
- this problematic bending stress can result in material-damaging overstressing of the telescoping drill string and, on the other hand, lead to uneven removal of soil material at the bottom of the borehole. It may even damage the rig and endanger the platform.
- the invention has for its object to provide a drill and a method for creating a hole, especially in a body of water from a floating platform, specify with which drilling can be performed very efficient and gentle on materials.
- the drilling apparatus is characterized in that a control unit is provided, which is designed to control and reduce the torque of the drill drive during the drilling operation to a threshold value, wherein the at least one drill string element with an existing friction on the contact surface to compensate for strokes further axially is displaceable.
- a basic idea of the invention is to compensate for relative movements of the drill to the bottom hole by a reliable extension and retraction of the drill string.
- the drill string can be composed of a single linkage with only one drill string element or of several string elements, in particular screwed.
- the torque is transmitted from stop elements on the drill drive to the stop bars of the drill string.
- the invention is based on the recognition that bear against high pressure forces in the circumferential direction of the axial stop bars during drilling operation. This leads to correspondingly high adhesive and frictional forces, so that an axial displaceability of the drill string element can be blocked.
- the reliable displacement is inventively achieved in that the friction is controlled and reduced at the contact surfaces of the drill string element to a sufficient degree for the process.
- the reduction of the friction is achieved by reducing the torque, which is intended for the pressing force and thus the adhesive / frictional force on the contact surfaces.
- the invention represents, so to speak, an ABS system, that is to say an anti-lock system, for drill pipe. This makes it possible to reliably compensate, for example, for a water stroke in the axial direction of the drill string. Overuse is avoided.
- the invention can also be used in drilling on land.
- Hub movements for the present invention can be understood in principle all movements in an axial direction of a drill string, which is the distance between a drill and a bottom hole in a hole change.

- the detector unit may be located on the floating platform or on the drilling rig standing on the floating platform.
- the detector unit may preferably be a linear acceleration sensor, which in particular determines accelerations in the axial direction of the drill pipe. From the measured accelerations, integration can be used to determine speeds and changes in position with respect to the movements in the axial direction of the detector unit itself and / or an evaluation unit connected to the detector unit.
- the detector unit can also be attached to a non-moving, especially at a point on land, and record the strokes. In this case, the lifting movements of the water body in the vicinity of the floating platform can be detected directly, or preferably the lifting movements of the drilling device itself can be determined.
- a measuring mark which is located on a surface of the water or preferably on the floating platform or on the drill, with a position-determining surveying instrument. From position changes can be concluded on the movements in the axial direction of the drill string.
- the detector unit is coupled to the control unit and that the torque can be reduced by the control unit when a stroke movement to be compensated is determined by the detector unit.
- the detector unit can detect occurring lifting movements and transmit them to the control unit. In principle, all ascertained lifting movements or only such lifting movements which take into account a stroke movement exceeding the critical value for the drilling operation can be taken into account and transmitted.
- the control unit communicating with the drill drive can reduce the torque based on the transmitted lift motions. In this case, stroke values or stroke ranges can be assigned individual torques. Also, an adjustment of the torque can be made continuously.
- lifting movements in particular those which exceed a predefined limit value, can be assigned a torque equal to zero, which corresponds to a stopping of the rotary drive.
- Recurring in particular periodic strokes by wave movements of a body of water, can be predicted after determination of the course of movement by the detector unit with known methods, including by means of a KALMAN filter.
- a compensation of such periodic strokes can be achieved with a periodic change in torque.

- Abtragstechnikmaschinee be attached to the drilling tool, which a Cause loosening of the soil material.
- removal tools may for example consist of chisels, blades or knives.
- the friction on the contact surface between the stop bars to compensate for the lifting movement is sliding friction. If the friction on the stop bars for compensation of the lifting movements is due to sliding friction, a torque can also be transmitted during the compensation. Thus, a force can be exerted on the bottom hole for the removal of soil material even with compensation of the strokes by the drilling tool. It can also be provided that the sliding friction for compensation of the lifting movements is equal to zero, which can be effected by stopping the rotary drive. Stopping can be a short period of time, in particular less than 1 s.
- the object mentioned according to the invention is achieved in that the torque is controlled and reduced during the drilling drive by a control unit to a threshold, in which a frictional force is formed on the contact surface, in which for compensating a stroke of the at least one Drill rod element is further axially displaceable.
- the drilling tool may, in particular, remain in contact with the bottom hole while the drilling tool is moving up and down.
- the torque transmission is adapted to the strokes, in particular reduced.
- An advantageous variant of the method according to the invention is when the distance between a drilling tool, which is arranged at a lower portion of the telescoping drill string, and the drill is changed in the compensation of the lifting movements.
- a change in the distance of the drilling tool may correspond to an axial change in the length of the telescoping drill string. The changes in the distance can be achieved that a bending of the drill string is reduced in an action of forces due to strokes and that a loss of contact of the drilling tool is prevented with the bottom hole.
- the lifting movements are detected by a detector unit and these are communicated to the control unit.
- the detector unit which may be located on the body of water, on the floating platform and / or on land, may communicate strokes to the control unit via data transmission over a cable or wirelessly.
- the reported strokes may include positions, changes in position, speeds, changes in speed, and / or accelerations of the body of water, the drilling rig, and / or the floating platform.
