Abstract

L'invention concerne un élargisseur à section d'alésage hybride, destiné à des opérations de forage terrestre de fond de trou. Cet élargisseur peut comprendre un corps formant alésoir présentant un axe de rotation, une périphérie extérieure, et des extrémités supérieure et inférieure, plusieurs molettes reliées à la périphérie extérieure et orientées vers le bas, qui définissent un profile de coupe de molettes présentant un diamètre de coupe, plusieurs lames fixes reliées à la périphérie extérieure et définissant un profile de coupe de lames fixes présentant un diamètre de coupe, chaque lame fixe étant reliée entre des lames de molette adjacentes. Au moins l'une des molettes peut être reliée de manière asymétrique autour de l'axe. Le diamètre de coupe du profile de coupe des molette peut être plus large que le diamètre de coupe du profile de coupe des lames fixes. Au moins une partie du profile de coupe des molettes peut être plus profond que le profile de coupe des lames fixes.
