Title
(EN) MULTI-FUNCTION DOWNHOLE TOOL
(FR) DISPOSITIF DE FOND MULTIFONCTION
Abstract
(EN)
A multi-function downhole apparatus (10) is described which comprises a tubular main body (12) having at least one recess (11) formed in its outer surface. The recess (11) is adapted to receive any of a set of interchangeable tool elements, which include stabiliser blades of different radial sizes, cleaning elements, roller reaming tool elements, a hole opener tool element, and a drilling casing shoe element. In particular, the apparatus allows drilling operations and wellbore cleaning operations to be carried out using the same tool body.
(FR)
L’invention concerne un dispositif de fond multifonction (10) comprenant un corps principal tubulaire (12) dont la surface extérieure présente au moins un renfoncement (11). Le renfoncement (11) est adapté pour recevoir l’un quelconque d’un jeu d’éléments d’outil interchangeables, comprenant des lames de stabilisation de dimensions radiales différentes, des éléments de nettoyage, des éléments d’outil d’alésage à molettes, un élément d’outil d’élargissement de trou et un élément de sabot de tubage de forage. Le dispositif permet notamment la réalisation d’opérations de forage et d’opérations de nettoyage de puits à l’aide du même corps d’outil.
