Definitions

  • Present invention relates to an arrangement for re ⁇ moving drill cuttings and the like from the upper end of a control pipe projecting upwards from a sea bottom in con ⁇ nection with well drilling in the sea bottom, where the drill cuttings are adapted to be lifted upwardly through the control pipe as it is drilled downwardly through the sea bottom.
  • Fig. 2 shows in a corresponding perspective the mounting unit mounted in place on the cover-base frame according to Fig. 1.
  • Fig. 8 shows schematically a hydraulic flow diagram in connection with the mounting unit as shown in Fig. 1-7.
  • Fig. 9 shows in part a vertical section of the mounting unit according to a first embodiment.
  • Carrier head 32 of the housing member 31 is further illustrated in Fig. 9 and 10.
  • An inner vertical sleeve portion 71 forms with its lower horizontal surface 71a a support against the carrier ring 33 on the drill stem 34, while an outer vertical sleeve portion 72 with an oblique surface 72a forms a supporting abutment against an equiva ⁇ lent oblique surface 37a in the upper guide surface 37 of the housing member 31.
  • the cylindrical peripheral surface of the sleeve portion 72 is provided with a first, axially extending, slot-shaped control groove 73 for the reception of a spring-loaded control member 74 fastened on the housing member 31 so as to prevent mutual turning of the carrier head 32 and the housing member 31.
  • the annular flange 82 is braced by means of vertically extending triangular plates 84 which are shown resting against a conical lead flange 35a at the top of a surroun ⁇ ding upper portion of the control pipe 35 projecting up- wards from the sea bottom. It is possible in a ready manner to leave the housing member section 31b internally in the control pipe 35 while remaining portions of the mounting unit 25 are drawn upwardly again to the rig, so that the control pipe 35 is ready for installing of other drilling equipment in connection with a riser pipe and the like.

Abstract

Canalisation de décharge (58) servant à évacuer les déblais de forage d'un tuyau de commande (25) lors du forage d'un puits au fond de la mer. Le tuyau de commande (25) comporte un tuyau de prolongement (31) et une ouverture de sortie latérale (en 46) menant à une canalisation de décharge (58) séparée par l'intermédiaire d'un ensemble d'aspiration par poussée d'eau sous pression intermédiaire (50, 54). La canalisation de décharge est adaptée pour porter les déblais de forage ou analogue directement jusqu'à une zone de décharge éloignée.
