  • An example of a handling device to be positioned when drilling holes is a per se known pincer system which is provided for connecting and separating linkage elements of a drill string and / or a so-called casing string with tubes for lining the borehole.
  • a per se known pincer system which is provided for connecting and separating linkage elements of a drill string and / or a so-called casing string with tubes for lining the borehole.
  • linkage elements or groups of linkage elements e.g. two or up to three linkage elements (so-called states), each separated from the drill string, so that it can be successively pulled up further out of the borehole.
  • drill string or drill string are used in the following. However, this is without departing from a broader generality, so that any use of the term drill string is also intended to include a casing string and any use of the term drill string also includes one or more pipes (casings) for lining the wellbore.
  • the clamp system For separating such a drill string, the clamp system is provided and the adjustment of the clamp system with respect to a connection point of the drill string has been done manually.
  • the forceps system is first positioned over the wellbore, and for proper alignment with respect to the joint to be loosened, suitable mobility of the forceps system, e.g. a translational mobility provided, so that in this regard a manual adjustment of the pliers system takes place until reaching the respective height of the connection point.
  • a laser pointer acting as a position indicator is proposed.
  • the laser pointer allows a pivoting movement in one plane (pitch movement) to Depending on the position of the drill string to be able to designate different heights of the joint.
  • the laser pointer as a position indicator is aligned with the respective junction and after positioning the respective orientation of the position indicator is confirmed. This orientation of the position indicator is recorded and converted into motion data for positioning the forceps system.
  • a handling device eg a tong system as mentioned above
  • WO 2009/148304 A is a method for welding pipe segments for underwater pipelines and concretely the detection of the end of a last segment of the pipeline and an end to be connected to another pipe segment described.
  • the measuring device provided for this purpose is movable relative to the ends of the tube segments to be detected, and the acquired data serve to control a welding device.
  • this movement data for example a height information derived from the position of the marking
  • a positioning of the handling device in particular a tong system as a handling device
  • a completion of the process of marking the joint is confirmed.
  • the position of the marking given at the time of the confirmation is recorded and made available in the form of a position value for further processing.
  • the position value determined in this way can then be converted into movement data for positioning the handling device.
  • Based on this movement data can be automatically positioned as a handling device, a pliers system with respect to the connection point and activated a control of the pliers system or enabled for activation. Activation of the forceps system then involves subsequent steps of disconnecting the linkage members at the junction.
  • This method is especially for use on a drilling rig, so a drilling rig for drilling deep wells, into consideration, so that the above-mentioned operator of such a drilling rig, such as a drill master, his tasks usually from a cab designed as cab (the Drillerkabine) performed in a simple and straightforward way for a correct positioning of the handling device and thus ensure a rapid and smooth distribution of the drill string.
  • the approach presented here can also be used when connecting rod elements (boring bars or casings) to the drilling or casing string.
  • rod elements boring bars or casings
  • a new linkage element must be combined with the drillstring.
  • a drilling device for example, a so-called top drive, or a so-called pipe manipulator - collectively referred to as a drilling device - brought a new linkage element and positioned above the drill string to then be connected to the pliers system with the drill string.
  • Vertical movements of the drilling device are required to raise the new linkage vertically above the drill string and to bring the lower end of the new linkage near the drill string or in contact with the drill string.
  • this last vertical movement can be automated if the vertical position of the upper end of the drill string is known.
  • the vertical position of the upper end of the drill string may be marked as well as a joint between two linkage members in an image taken from the respective section of the drill string.
  • the vertical position of the upper end of the drill string can then be converted into movement data for a drilling device of the above type. Thereafter, the drilling device with the new linkage element can automatically approach the upper end of the drill string, ie lower the new linkage element in the direction of the upper end of the drill string.
  • the device comprises means for carrying out the method or its embodiments, in particular a Camera and means for confirming a position of the marker in the image captured by the camera and means for detecting a position of the marker in the image and means for converting the detected position into motion data for positioning the handling device.
  • the operator in the picture denotes (marks) the connection point between two linkage elements of the drill string by means of a mark which is movable in the picture.
  • a horizontal line that can be moved in the image is considered as a marking.
  • This horizontal line is moved vertically in the image until coverage or sufficient coverage with the junction of two linkage elements is achieved.
  • the thus achieved vertical position of the mark can be converted into movement data for adjusting the handling device.
  • This embodiment of the method has the advantage of easy implementation. The camera takes exactly one picture of the drill string and the mark is moved in this picture.
  • a section of the recorded image is displayed to the operator and that the operator marks the connection point between two linkage elements of the drill string by moving the section relative to the recorded image.
  • This aspect of the invention takes into account that today suitable cameras are available for industrial use, which can produce digital images with a very high resolution; at eight megapixels, for example, 3,264 x 2,448 pixels, at 14 megapixels to Example 4,536 x 3,024 pixels.
  • Such image dimensions and expected future even higher image dimensions can be displayed on conventional screens only if the image is reduced with a loss of detail shown. However, a loss of detail is sometimes problematic if, as here, it is important to reliably identify comparatively small details.
  • the joint of two linkage elements appears in the captured image in the broadest sense as a horizontal line.
  • a reduction of the image taken in each case for displaying an image on a screen can therefore result in such a line no longer being or no longer being reliably recognizable.
  • the representation of the section is preferably matched to the resolution of the respective screen. If this permits a resolution of, for example, 1024 ⁇ 768 pixels, this specifies the dimensions of the detail.
  • each snapshot pixel of the captured image within the snippet is represented by exactly one pixel of the screen. All recorded details of the image can thus also be displayed on the screen. A loss of detail does not arise.
  • connection point between two linkage elements can lie in each section of the recorded image
  • the section shown in each case can be moved relative to the recorded image.
  • One for the operator Particularly practical embodiment consists in the fact that the section shown has a fixed marking, for example in the form of a horizontal line (line cursor) in the center of the picture, and that for marking a recognized connection point between two linkage elements of the cutout is moved relative to the overall picture, until the stationary line cursor and the connection point shown in the picture are brought into line. This has the advantage that a suitable movement of the cutout to designate the connection point is sufficient.
  • the otherwise also possible movement of the section until it detects the junction between two linkage elements and a subsequent displacement of a line cursor within the section means two independent positioning operations and it is expected that two independent positioning operations take more time than the movement of a section with a fixed line cursor relative to the overall image.
  • a position of the line cursor in the image is converted into movement data for positioning the handling device on the basis of a distance between the camera and the drill string.
  • the determination of movement data for the handling device is thus attributed to simple trigonometric conditions in a right-angled or a general triangle. For calibration is only one Determining the distance between the location of the camera and the drill string necessary.
  • a position of the line cursor in the image is converted into movement data for positioning the handling device on the basis of a correlation table.
  • a correlation table can be deposited as part of a calibration, which height is detected on the drill string, for example, by the bottom and the top line of the image.
  • By interpolation can then be determined for each line of the image, a corresponding height value.
  • a corresponding height value can be determined on the basis of a position of the line cursor. The respectively determined height value can be used to control the handling device.
  • an operating element For movement and positioning of the line cursor is an operating element in the manner of a trackball or the like into consideration.
  • an operating device is used, which is already present on a control station, for example in a cab of the drill, and is used there for other control or positioning tasks, for example a so-called master switch. Then, by switching to the functionality for semi-automatic adjustment of a handling device, the already existing operating device as a control element to move and position the line cursor.
  • the handling device is automatically adjustable relative to the joint and a related development of the method and its embodiments is that the respective handling device is automatically adjusted relative to the joint.
  • a tong system for separating two linkage elements can be adjusted relative to the connection point.
  • a Topdrive, a Pipe Manipulator or the like a new linkage element is adjusted relative to an upper end of the drill string as a marked joint, the approach presented here is not only in removing linkage elements and splitting the drill string, but also in installing linkage elements, ie Combining new linkage elements with the downhole drillstring usable.
  • a drilling device in particular a top drive, a pipe manipulator or the like, functions as a handling device, in one embodiment of a method for determining movement data for the necessary adjustment processes or for the automatic Execution of the movements or movements required for the adjustment provided that the adjustment of the new linkage element initially with a first predetermined or predetermined speed and below a predetermined or predeterminable distance of the new linkage element to the upper end of the drill string with a reduced compared to the first speed, predetermined or predetermined second speed.
  • the first speed can be set comparatively high, so that the installation of new linkage elements can proceed as quickly as possible.
  • a further advantageous embodiment of a method for connecting drill pipe elements to the drill string takes into account that the drill string normally contains liquid, in particular drilling fluid with drilling residues. Then the free thread of the upper end of the drill string forming linkage element can not be cleaned. Usually, in addition to the cleaning and a Fettung (for example, with the so-called drill dope) provided or required. In order to be able to make at least the cleaning, possibly the cleaning and the subsequent greasing, it is necessary that a part of the liquid standing in the drill string is removed. So far, a displacement body is used, which is introduced into the upper end of the drill string and then removed again.
  • a Fettung for example, with the so-called drill dope
  • a portion of the liquid standing there is displaced from the drill string, so that after removing the displacement body, the thread can be cleaned and / or greased.
  • This process can also be automated on the basis of the approach described here. If the position of the upper edge of the drill string is known, this can also be converted into motion data for automatically positioning a handling device with a displacer relative to the upper end of the drill string as a marked joint, so that the displacer with the handling device automatically displaces liquid from the drill string is introduced into the upper end of the drill string and the handling device is then moved away from the area of the drill string after the automatic removal of the displacer from the drill string.
  • Both automatic positioning operations can also be combined to an automatic movement based on a known vertical position of the upper edge of the drill string: then, before the adjustment of the new drill string member with respect to the downhole drill string an automatic Displacement of liquid from the drill string by means of automatically moving with a corresponding handling device displacement body, possibly also a subsequent automatic cleaning and / or greasing with the same handling device or leading a cleaning tool handling device and then automatically the adjustment of the new drill string element with respect to the upper End of the drill string.
