Abstract

La présente invention concerne un corps de verrouillage pour l'utilisation dans un ensemble tête de forage. Ledit corps de verrouillage comprend un sous-ensemble régulateur de fluide, un élément clapet de non-retour, et/ou une broche creuse. Une partie extrémité distale du corps de verrouillage comprend une section orifice qui définit une chambre pour recevoir l'élément clapet de non-retour et pour favoriser le mouvement de l'élément clapet de non-retour entre une position de blocage et une position d'ouverture. La broche creuse du sous-ensemble régulateur de fluide est accouplée fonctionnellement avec la chambre de la section orifice et supporte l'élément clapet de non-retour dans la position de blocage. Une partie extrémité proximale du corps de verrouillage supporte le sous-ensemble régulateur de fluide de l'ensemble tête de forage dans une position fonctionnelle. Le corps de verrouillage comprend des protubérances mâles qui s'étendent vers l'intérieur vers un axe longitudinal du corps de verrouillage, et sont espacées dudit axe longitudinal du corps de verrouillage. Une pluralité de canaux s'étendent radialement vers l'extérieur à partir de l'axe longitudinal du corps de verrouillage, s'étendant entre des protubérances mâles adjacentes.
