Definitions

  • the invention relates to a cable reel for introducing a data control cable into a drill string of a drilling system, in particular a horizontal drilling system, which has a rotary power head, a tubular drill string rotatably coupled therewith, made up of a plurality of tubular rod sections which are rotatably coupled to one another, a drum carrier which is rotatably coupled to the rotary power head, a comprises a cable drum rotatably mounted on the drum carrier, a rotary feedthrough for the data control cable from the cable drum to the drum carrier, a rotary feedthrough on the drill string for carrying out a connection of a data control cable to the outside.
  • horizontal drilling rigs are able to drill directional bores in the ground, in rock or in rock and have a power turret, which is guided on a drill mast or a frame and rotates with a drill string, consisting of each other element-wise rotatably coupled pipe sections, and drives this drill string into the ground.
  • These directional bores are created in order to lay product pipes, for example communication lines, gas lines, oil lines, water lines or the like in inaccessible terrain, in particular below railway lines, highways, rivers or the like. Holes that run essentially horizontally can be created over large distances. This simplifies the laying of product pipes and the laying costs can be reduced considerably.
  • a pilot bore is first created by driving a drill string into the ground in a directional manner by means of the power rotary head, which undercuts an existing obstacle and emerges from the ground again at a predetermined point.
  • an expansion head At the end of the drill string emerging from the ground is connected to an expansion head which is drawn into the pilot bore with the drill string and expands it.
  • a product pipe with a diameter that essentially corresponds to the expansion head can be pulled into the bore.
  • the drill head is connected to the data cable routed through the drill string and to the carrier device on the surface. In this way, it is possible to ensure contact between the drill head and the carrier device, regardless of the distance and depth of the bore.
  • the data cable does not twist during the drilling process, it is out of the DE 202 02 395 U1 known to rotatably arrange a drum on which the data guide cable is wound in a drum carrier, the drum carrier in turn being rotatably connected to the drill string. This causes the drill string and the data transmission cable to rotate with one another, so that the risk of knots and cable breakage is reduced.
  • the attached drawing shows only part of a horizontal drilling rig.
  • This sub-area comprises a frame on which a power rotary head, which drives a drill string, is movably arranged.
  • a fixed flushing adapter for flushing fluid introduced into the drill string is also attached to the frame, which is connected via a rotary leadthrough to a connection on the power rotary head and via a similar further rotary leadthrough to another pipe connection that rotates in a bearing.
  • a power and data conduction line in the form of an electric cable is led from the drill string through the power rotary head, the flushing adapter and the pipe connection to a rotatable drum carrier coupled to the drill string.
  • the drum carrier is designed as a closed frame in which an inner cable drum is mounted with an axis of rotation perpendicular to the axis of rotation of the drum carrier. A supply of electrical cables is wound onto the inner cable drum. The rotation of the drum carrier in the same direction as the drill string is brought about by the aforementioned connection.
  • a hydraulic motor acts to brake or drive the inner cable drum.
  • An electrical connection leads from the inner cable drum via a first rotary leadthrough provided with slip rings to a further rotary leadthrough through which the hydraulic lines for the hydraulic motor and the electric cable from the first rotary leadthrough are passed.
  • the hydraulic lines for the hydraulic motor are led from the further rotary feedthrough to a hydraulic control, which is used to set the braking torque or the drive torque of the hydraulic motor.
  • the electrical connection routed through the further rotary feedthrough conducts the signals routed through the electrical cable in a manner not shown to a carrier device which receives and processes the signals in order to apply the corresponding signals to a direction control device arranged in the drill head.
  • the electric cable also serves to supply the drill transmitter with the electrical energy required for its operation in the area of the drill head.
  • a conical valve seat is arranged in a flange of the pipe connection, which with a. elastically deformable valve ball cooperates.
  • This valve ball has a bore through which the electric cable is led from the cable drum to the drill string.
  • valve ball Since there is no relative movement of the electric cable with respect to the drill string during the drilling process and the application of flushing suspension, the valve ball provides a static seal, during which the electric cable does not slide against the rubber ball.
  • a hydraulic motor an electric motor can also be used, which is suitable both as a brake motor and as a drive motor. In this case, a corresponding electrical control device is required instead of the hydraulic control.
  • the horizontal drilling system described has proven itself very well in connection with the cable reel, especially on large horizontal drilling systems in operation, but the cable reel requires additional space for the cable drum and for a necessary extension of the frame to support the rotary feedthrough located opposite to the power turret on the cable drum.
  • an electrical potential between the conductor and the rod casing which is designed so that in the event of an electrical connection between the rod casing and the electrical conductor via the drilling fluid, the conductor does not act as an anode and on which electrical conductor no anodic reaction and thus no oxidation with an interruption of the conductivity of the non-insulated sections of the conductor takes place.
  • a cable reel is not mentioned in this document, nor is it whether the electrical conductor rotates with the drill rod or whether a rotary feedthrough is provided on the drill head or in the area of the voltage source.
