Title
(EN) DRILLING DEVICE FOR USE ESPECIALLY DURING DIRECTIONAL DRILLING FOR RECOVERY OF GEOTHERMAL ENERGY
(FR) DISPOSITIF DE FORAGE DESTINÉ À ÊTRE UTILISÉ SPÉCIALEMENT PENDANT UN FORAGE DIRECTIONNEL POUR LA RÉCUPÉRATION D'ÉNERGIE GÉOTHERMIQUE
Abstract
(EN)
A drilling device with a drilling derrick above a base structure 2, wherein the drilling derrick 1 is provided with a winch 13 and a snatch block (14) for lifting and lowering a drilling machinery 7 connected to the surface via three or more flexible hoses and a centrally disposed hoisting wire with integrated electric and fibre cables 3. The drilling machinery 7 is assembled from a drill bit 18 connected to a drilling motor and gear 20 via a stabilizer 19. The drilling motor and gear are connected, in turn, to a directional control 21 and further, via the intermediate sub (22), to a rolling anchor connected to the swivel connection 25. Drill collars are disposed above the swivel 25 in order to control the weight on the drill bit 18.
(FR)
L'invention porte sur un dispositif de forage présentant un derrick de forage au-dessus d'une structure de base 2, dans lequel dispositif le derrick de forage 1 comporte un treuil 13 et une poulie à chape ouvrante 14 pour soulever et abaisser une machinerie de forage 7 reliée à la surface par l'intermédiaire de trois ou plus de trois tuyaux souples et d'un fil de levage disposé de façon centrale à des câbles électriques et à fibres intégrés 3. La machinerie de forage 7 est assemblée à partir d'un trépan de forage 18 relié à un engrenage et à un moteur de forage 20 par l'intermédiaire d'un stabilisateur 19. L'engrenage et le moteur de forage sont eux-mêmes reliés à une commande directionnelle 21, et, de plus, par l'intermédiaire de la réduction intermédiaire 22, à une ancre de roulement reliée à la liaison pivotante 25. Des colliers de forage sont disposés au-dessus de la liaison pivotante 25 afin de contrôler le poids sur le trépan de forage 18.
