  • the invention relates to a filling device for filling of drilling fluid in drill pipe or in Bohrrat a drill string, as used in oil or gas wells and a method for their operation.
  • drilling methods are used in which drilling fluid are filled in certain compositions in the drill pipe of a drill string and directed to the drill head.
  • the individual drill pipe are formed as a hollow cylinder and provided at the ends with openings for the passage of drilling fluid to the drill head.
  • the drilling fluid is conducted during the drilling process through the drill pipe into the borehole and sprayed through the nozzles arranged at the drill head under high pressure in the borehole.
  • the resulting in drilling operation cutting residues are thus continuously removed from the teeth of the cutting tool and secured its necessary cooling.
  • the fluid level should fill the cavity of the borehole as completely as possible and reach to the surface of the drilling platform.
  • the drilling fluid also protects against uncontrollable gas leakage, so-called blow-outs and serves to transport the cuttings from the bottom of the well in Bohrschlammauffangvortechnischen the drilling platform.
  • the drill string itself consists of a plurality of coupled drills, which in turn comprise a plurality of drill pipes.
  • the drill string must be continuously extended by new drill string.
  • the drill pipes are combined into drills and transported by the elevator on the platform to the well and coupled to the drill string.
  • drilling fluid In order to maintain the necessary drilling fluid level in the well, which is also important for an effective circulation of the drilling fluid, drilling fluid must be supplied with the extension of the drill string.
  • the drill string After completion of the drilling operations, the drill string is removed from the wellbore in most cases and casings used to stabilize and line up the wellbore.
  • filling valves are usually coupled to the drill string and partially lowered into the filled with drilling fluid casing, where then supplied by pumping drilling fluid is dispensed via differently designed closable openings and nozzles in the annulus between the drill string and casing .
  • the filling valve also prevents the undesired backflow of contaminated drilling fluid, also called drilling mud, into the drill string after the pump is shut off.
  • a drilling fluid refilling apparatus which discharges the drilling fluid into the freed annulus between the drill string and the walls of the wellbore.
  • the cylindrical filler described herein is bolted to the topdrive of the elevator and the tubular drill string.
  • the cylindrical walls provided with one or more laterally arranged outlet openings for the drilling fluid to be dispensed can be closed by a valve slidable between two positions.
  • the refilling device is also used for cementing casings and must be lowered both for filling the well with drilling fluid, as well as for cementing in the well.
  • a filling device for filling a deep drill string or one or more drill trains is described with drilling fluid.
  • This filling device consists of a cylindrical body, which has a piston chamber with at least one Includes filling opening for drilling fluid and an end piece, which has connecting means and is used for coupling to the top drive of Tiefbohrstranges.
  • a hollow cylindrical filling piston for discharging drilling fluid into the drill string in the piston chamber of the cylindrical base body is arranged to slide axially movable.
  • the filling opening described here is not closable and there is also no device provided with which the hollow cylindrical filling piston can be opened and discharged for dispensing drilling fluid.

  • Essential components of the inventive solution are a cylindrical body comprising a piston chamber with at least one closable filling opening for drilling fluid and having an end piece for coupling the filling device to the Topdrive (rotary drive head) of the Tiefbohrstranges.
  • the inventive filling device is further characterized in that a hollow cylindrical filling piston for discharging drilling fluid into the drill string in the piston chamber of the cylindrical base body is arranged to slide axially movable. In the cavity of the filling piston also engages an axially movable piston valve and cooperates with the piston chamber such that caused by the Bohrierikeitstik opening position and caused by an external media pressure, in particular compressed air closing positions is ingestible and effective.
  • the device of the invention is preferably used to fill up drills or drill pipes with drilling fluid during their installation to reposition the drill string.
  • the filling device is mounted on the drilling platform in the coupling device of the elevator and connected to the pump system for the supply of drilling fluid, and an external pressure medium source for actuating the filling valve.
  • the embodiment relates to the filling device according to the invention and a method for its operation for filling of drilling fluid in a Bohrzug which serves to extend the drill string during installation. Depending on the drill hole depth to be achieved, this process must be repeated very frequently.
  • the frequency of the drill string to be used and replenished for the extension of the drill string, as well as the changeover time required therefor, are optimization variables that can be influenced by the technique used.
