Title (EN) PUSH-THE-BIT BOTTOM HOLE ASSEMBLY WITH REAMER
(FR) ENSEMBLE DE POUSSÉE DE TRÉPAN EN FOND DE TROU AVEC ALÉSOIR
Abstract:
(EN) A method for constructing a wellbore includes drilling a wellbore along a trajectory using a bit; reaming the diameter of a portion of the drilled wellbore to enlarge a portion of the wellbore; and altering the trajectory of the bit by applying a lateral force to the enlarged diameter wellbore. Reaming the diameter of the portion of the drilled wellbore increases the dogleg of the wellbore.
(FR) La présente invention concerne un procédé de construction d'un puits de forage, comprenant le forage d'un puits de forage le long d'une trajectoire à l'aide d'un trépan ; l'alésage du diamètre d'une partie du puits de forage foré afin d'agrandir une partie du puits de forage ; et la modification de la trajectoire du trépan par application d'une force latérale au puits de forage de diamètre agrandi. L'alésage du diamètre de la partie du puits de forage foré augmente la déviation du puits de forage.
