Definitions

  • the present invention relates to a pressure pipe string for continuous fusion drilling for deep drilling.
  • the invention also relates to a method for producing this pressure train as well as for advancing it in the borehole and thereafter breaking it off.
  • the invention also relates to devices for performing the aforementioned methods.
  • Continuous screed drilling is understood to mean a drilling technique in which a temperature is generated in front of or at the drill head tip such that the rock is melted there and the rock melt due to the pressure exerted on the drill head into that due to thermostress resulting cracks (thermo-fraction) is pressed off in the side rock.

  • German laid-open specification 37 01 676 AI is a profile melting drilling method, in which only the outer profile of a borehole is melted in a minimal cross section, which just offers space for the drilling device and its supply lines.

  • the core of the borehole is increased in volume and is sheared off in sections after passing through the inner cooling zone of the melting drilling rig and is conveyed upwards.
  • Both fusion drilling processes are designed as continuous processes, that is to say the drilling process takes place in one go up to the drilling target.
  • the lateral pressing of the melted drilling material creates a solid borehole casing which serves as a guide for the melting drilling machine and prevents side rocks from breaking into the borehole.
  • a continuous drilling process without interruption and "round trips" is possible by means of such a fusion drilling method even at depths of 10,000 m to 15 * 000 m because the service life of the pressure drilling head can be designed so that it has a service life that is Sufficient achievement of the drilling target.

Abstract

Les canalisations d'alimentation (10, 11, 16), les canalisations de mesure et les canalisations de commande des équipements de forage sont logées à l'intérieur de la colonne de tubes de pression (48) en vue du forage thermique en continu de puits profonds. La colonne de tubes renferme au moins deux composants (4) en forme de coquille dont chacun forme un segment longitudinal (4) d'un tube, ainsi que des moyens pour assembler un tube étanche extérieurement lisse qui résiste aux efforts de tension et de compression. Dans le procédé pour fabriquer, guider et ensuite démonter une colonne de tubes de pression en vue du forage thermique en continu de puits profonds, les canalisations d'alimentation (10, 11, 16), de mesure et de commande sont passées en continu le long de la profondeur à forer. A cet effet, pendant le guidage du forage, plusieurs composants (1, 4) sont assemblés en tronçons autour des canalisations d'alimentation (10, 11, 12), de mesure et de commande afin de former une colonne hermétique de tubes de pression (48), résistante aux efforts de tension et de compression et qui est ensuite guidée en continu. Le dispositif permettant la mise en oeuvre de ce procédé comprend un carrousel d'alimentation (60) pour chaque canalisation d'alimentation (10, 11, 16), sur lequel est enroulée cette dernière. Ledit carrousel (60) comporte une plateforme (62) circulaire montée rotative et motorisée pour maintenir les enroulements. En outre, le dispositif comprend une tour d'installation (40) à plusieurs étages (41 - 44) dans lesquels sont répartis des moyens (50, 51; 46, 47) permettant le montage par tronçons, le guidage en continu et le démontage ultérieur de la colonne de tubes de pression (48).
