Title (EN) OPTIMIZATION OF DYNAMICALLY CHANGING DOWNHOLE TOOL SETTINGS
(FR) OPTIMISATION DE RÉGLAGES D'OUTILS DE FOND DE PUITS CHANGEANT DYNAMIQUEMENT
Abstract:
(EN) A computer-assisted method for optimizing a drilling tool assembly, the method comprising defining a desired drilling plan; determining current drilling conditions; determining current drilling tool parameters of at least two drilling tool assembly components; analyzing the current drilling conditions and the current drilling tool parameters to define a base drilling condition; comparing the base drilling condition to the desired drilling plan; determining a drilling tool parameter to adjust to achieve the desired drilling plan; and adjusting at least one drilling tool parameter of at least one of the two drilling tool assembly components based on the comparing the base drilling condition to the desired drilling plan.
(FR) L'invention concerne un procédé assisté par ordinateur permettant d'optimiser un système d'outils de forage, lequel procédé consiste à définir un plan de forage voulu, à déterminer des conditions de forage actuelles, à déterminer des paramètres d'outils de forage actuels pour au moins deux composants de système d'outils de forage, à analyser les conditions de forage actuelles et les paramètres d'outils de forage actuels afin de définir une condition de forage de base, à comparer la condition de forage de base au plan de forage voulu, à déterminer un paramètre d'outil de forage à ajuster afin d'obtenir le plan de forage voulu, et à ajuster au moins un paramètre d'outil de forage pour au moins un des deux composants du système d'outils de forage sur la base de la comparaison entre la condition de forage de base et le plan de forage voulu.
