Title (EN) CLOSED LOOP CONTROL OF DRILLING CURVATURE
(FR) COMMANDE EN BOUCLE FERMÉE DE COURBE DE FORAGE
Abstract: front page image
(EN)A downhole closed loop method for controlling a curvature of a subterranean wellbore while drilling includes drilling the subterranean wellbore using a drilling tool. A set point curvature is received at a downhole controller. Sequential attitude measurements made at a single axial location on the drilling tool and a rate of penetration of drilling are processed to compute a curvature of the wellbore being drilled. The drilling direction is adjusted such that the computed curvature is substantially equal to the set point curvature.
(FR)Un procédé en boucle fermée de fond de trou visant à commander une courbe d'un puits de forage souterrain pendant le forage comprend le forage du puits de forage souterrain à l'aide d'un outil de forage. Une courbe de consigne est reçue au niveau d'un contrôleur de fond de trou. Des mesures d'orientation séquentielles effectuées en un seul emplacement axial sur l'outil de forage et une vitesse de pénétration de forage sont traitées pour calculer une courbe du puits de forage en cours de forage. La direction du forage est ajustée de sorte que la courbe calculée est sensiblement égale à la courbe de consigne.
