Subsequently, the drill drive, which can also be referred to as a power rotary head, reset and provided with a new drill pipe element. This has on its underside a threaded portion, which can be screwed suitably in an associated threaded portion at the end of the already drilled drill string element. Subsequently, a further drilling step can be carried out.
  • drill string elements When creating, for example, a water, gas or oil well with relatively large drilling depths, it may be necessary to assemble a plurality of drill string elements. In the reverse manner, the drill string elements can also be pulled out of the ground again after the bore has been carried out, and the screw connections can be loosened.

  • the drilling apparatus is characterized in that a displacement measuring device is provided, by which an adjustment of the drill drive along a guide can be detected as the actual value that detected by the controller, a speed of the drill drive during screwing and taking into account a predetermined thread constants an adjustment as desired Value can be determined is that by the control unit, a comparison of desired value and actual value feasible and a difference value can be determined and that the drill drive and / or the adjusting device is adjustable by the control unit according to the determined difference value.
  • a displacement measuring device is provided, by which an adjustment of the drill drive along a guide can be detected as the actual value that detected by the controller, a speed of the drill drive during screwing and taking into account a predetermined thread constants an adjustment as desired Value can be determined is that by the control unit, a comparison of desired value and actual value feasible and a difference value can be determined and that the drill drive and / or the adjusting device is adjustable by the control unit according to the determined difference value.
  • a basic idea of the invention is to carry out a control of a screwing movement based on a displacement during screwing.
  • a theoretical adjustment path is determined as a function of the rotational speed of the drill drive, that is to say in particular the number of revolutions during screwing, and a predetermined thread constant. It can thus be determined which theoretical adjustment path the drill drive has to perform in order to exactly follow the axial feed during screwing.
  • This calculated displacement is stored as a target value in a control unit.
  • the actual traverse path of the drill drive during screwing is recorded as an actual value via a displacement measuring device.
  • a comparison of desired value and actual value takes place, whereby optionally a difference value results.
  • an adjustment of the drilling drive and / or the adjusting device can then take place until the actual value approaches or corresponds to the desired value.
  • the drilling device may be a stationary drilling rig or a mobile drilling rig on a carrier vehicle.
  • any suitable device can be used as a setting device for moving the drill drive, such as chain or spindle drives.
  • the adjusting device it is particularly preferred for the adjusting device to have at least one setting cylinder and / or one winch.
  • the one or more adjusting cylinders may be in particular hydraulic cylinders, which are arranged on the mast for moving the drill drive.
  • the thread constant comprises a thread pitch or a pitch.
  • a thread value can be determined which axial displacement results in a single revolution.
  • an axial displacement can be calculated without further ado.
  • control unit has an input station for inputting data, in particular the thread constants.
  • the input station can have a conventional human-machine interface, in particular an input terminal or a touch screen.
  • the input station has a display on which possible thread constants can be displayed.
  • the usual thread types and thread sizes for drill rods can be stored in the control unit in a corresponding data memory. These possibilities can be shown on the display so that an operator only has to make a selection of the possible thread constants.
  • a further preferred embodiment of the invention can be seen in that a device for automatically detecting the thread constants is provided.
  • a queryable data memory such as an RFID chip
  • a camera system can be provided which detects a threaded area and determines the corresponding thread constant.
  • the data entry station can also be used to enter other data, such as operating data such as heading and drilling speed, etc.
  • the drilling device also has an overload protection when screwing, wherein an axial load on the drill drive or the adjusting device is detected.
  • an axial load on the drill drive or the adjusting device is detected.
  • the screwing process can be slowed down or preferably terminated.
  • the detection of a load thus represents a safety measure, which is not used to control the Verschraubvorganges.
  • the inventive method is characterized in that a displacement measuring device is provided, with which an adjustment of the drill drive along the guide during screwing is detected as the actual value that is detected by the control unit, a speed of the drill drive during screwing and taking into account a predetermined thread constants Adjustment path is determined as a target value that is compared by the control unit, the target value with the actual value and a difference value is determined and that the drill drive and / or the adjusting device is adjusted by the control unit according to the determined difference value.
  • the inventive method is carried out in particular with the drilling device described above. It can be achieved the advantages described above.
  • a preferred method variant of the invention is that a rotational speed, a rotational direction and / or a rotational speed of the drill drive is adjusted until the actual value corresponds to a desired value.

  • the method can be carried out with different objectives, such as to achieve the fastest possible screwing of the drill string.
  • a particularly efficient drilling operation can be achieved.
  • An advantageous variant of the method according to the invention is that the drill drive and the adjusting device are operated so coordinated that on the threaded areas a small load and / or friction occurs. As a result, a particularly thread-conserving operation can be achieved. This saves energy and overall increases the life of the drill string elements.
