A centralizer (101) comprises two annular bands (102, 103) which are spaced apart by a plurality of hollow members (104, 105, 106) extending therebetween. The hollow members (104, 105, 106) overlie openings (110-115; 116-121) in the annular bands (102, 103) respectively. In use, fluid can enter and leave the hollow member via inter alia the openings. This flow helps maintain a film of fluid between the annular bands (102, 103) and the tubular on which the centralizer is mounted and thus facilitates rotation of the tubular with respect to the centralizer.
L'invention concerne un centreur (101) comprenant deux courroies annulaires (102, 103) séparées par plusieurs éléments creux (104, 105, 106), qui s'étendent entre ces courroies. Ces éléments creux (104, 105, 106) recouvrent des ouvertures (110-115; 116-121), ménagées sur chaque courroie annulaire (102, 103). Lorsque ce centreur fonctionne, un fluide peut pénétrer dans un élément creux et en ressortir par l'une desdites ouvertures. Ce fluide forme une couche de fluide entre les courroies annulaires (102, 103) et le matériel tubulaire sur lequel le centreur est monté, facilitant ainsi le pivotement de ce matériel tubulaire par rapport audit centreur.
