Title (EN) VIBRATION GENERATOR FOR A DRILLING INSTALLATION, UNDERWATER DRILLING INSTALLATION AND UNDERWATER DRILLING SYSTEM
(FR) GÉNÉRATEUR DE VIBRATIONS POUR UNE INSTALLATION DE FORAGE, INSTALLATION DE FORAGE SOUS-MARINE ET SYSTÈME DE FORAGE SOUS-MARIN
Abstract:
(EN) A vibration generator (9) for a drilling installation comprises a housing (16), at least one rotation body (17), a suspension (24) by means of which the rotation body is suspended rotatably within the housing, the mass centre of the rotation body (17) being eccentric with respect to the rotation axis of the suspension, and a drive (18) for rotating the rotation body. The housing (16) holds a fluid (15) which is in contact with the rotation body (17) whereby relative rotation between the rotation body and the fluid generates a flow resistance and in that the rotation body comprises flow resistance reduction means (25).
(FR) L'invention concerne un générateur de vibrations (9) pour une installation de forage comprenant un boîtier (16), au moins un corps de rotation (17), une suspension (24) au moyen de laquelle le corps de rotation est suspendu en rotation à l'intérieur du boîtier, le centre de masse du corps de rotation (17) étant excentrique par rapport à l'axe de rotation de la suspension, et un entraînement (18) pour l'entraînement du corps de rotation. Le boîtier (16) contient un fluide (15) qui est en contact avec le corps de rotation (17), moyennant quoi une rotation relative entre le corps de rotation et le fluide génère une résistance à l'écoulement et le corps de rotation comprend un moyen de réduction de la résistance à l'écoulement (25).
