Title (EN) BOTTOMHOLE ASSEMBLY (BHA) STABILIZER OR REAMER POSITION ADJUSTMENT METHODS AND SYSTEMS EMPLOYING A COST FUNCTION
(FR) PROCÉDÉS ET SYSTÈMES DE RÉGLAGE DE POSITION DE STABILISATEUR OU D'ALÉSOIR D'ENSEMBLE DE FOND DE TROU (BHA) METTANT EN ŒUVRE UNE FONCTION DE COÛT
Abstract:
(EN) A system that includes a drillstring with a bottomhole assembly (BHA). The system also includes at least one stabilizer or reamer integrated with the BHA, wherein each of the at least one stabilizer or reamer includes a position adjustment assembly. The system also includes a processing unit that provides control signals to each position adjustment assembly, wherein the control signals are based on a cost function.
(FR) L'invention concerne un système qui comprend un train de tiges comportant un ensemble de fond de trou (BHA). Le système comprend également au moins un stabilisateur ou alésoir intégré au BHA, chacun desdits stabilisateur ou alésoir comprenant un ensemble de réglage de position. Le système comprend également une unité de traitement qui fournit des signaux de commande à chaque ensemble de réglage de position, les signaux de commande étant basés sur une fonction de coût.
