Abstract

L'invention concerne un stabilisateur de forage destiné à être monté sur une masse-tige. Le stabilisateur comporte un manchon rigide dont le passage intérieur 9 est muni d'une nervure centrale 56. Une paire de bagues fendues de blocage 83, 74 est introduite dans chaque extrémité du manchon. Les bagues comportent des surfaces coniques coopérantes de sorte que, lorsqu'un capuchon d'extrémité 12 est vissé dans le manchon, les bagues sont serrées l'une contre l'autre, la bague extérieure étant repoussée contre la bague intérieure et serrée contre le manchon et la bague intérieure étant serrée contre la masse-tige. La bague extérieure comporte une nervure 82 et une rainure 84 qui coopèrent avec une rainure 20 et une nervure 22 du capuchon de sorte que lorsque le capuchon est dévissé la bague extérieure est automatiquement séparée de la bague intérieure. Application aux forages pétroliers.A drill stabilizer for mounting on a drill pipe is disclosed. The stabilizer comprises a rigid sleeve, the interior passage 9 of which is provided with a central rib 56. A pair of split locking rings 83, 74 is introduced into each end of the sleeve. The rings have cooperating taper surfaces so that when an end cap 12 is screwed into the sleeve the rings are clamped against each other with the outer ring pushed against the inner ring and clamped against the sleeve. sleeve and inner ring being tight against the drill collar. The outer ring has a rib 82 and a groove 84 which cooperate with a groove 20 and a rib 22 of the cap so that when the cap is unscrewed the outer ring is automatically separated from the inner ring. Application to oil drilling.
