Abstract

L'invention porte sur un dispositif pour le couplage à un tuyau de forage rotatif pour réguler la pression d'un système de forage. Le dispositif comprend une surface interne destinée à s'enrouler autour d'une partie d'un tuyau de forage rotatif et ayant un diamètre interne. Une première partie effilée est opposée à une seconde partie effilée, avec une partie centrale entre celles-ci, comprenant un diamètre externe supérieur au diamètre interne. Les première et seconde parties effilées sont chacune effilées à partir de la surface externe jusqu'à la surface interne. La partie centrale, la première partie effilée et la seconde partie effilée forment une surface externe pour traverser de façon étanche un élément de scellement étanche d'un système de forage à pression régulée. Au moins une partie de la surface externe correspondant à la partie centrale comprend un matériau à faible frottement.
