Title (EN) DRILL BIT SUBSYSTEM FOR AUTOMATICALLY UPDATING DRILL TRAJECTORY
(FR) SOUS-SYSTÈME DE TRÉPAN POUR METTRE À JOUR AUTOMATIQUEMENT UNE TRAJECTOIRE DE FORAGE
Abstract:
(EN) A drill bit subsystem can include a drill bit, a processor, and a non-transitory computer-readable medium for storing instructions and for being positioned downhole with the drill bit. The instructions of the non-transitory computer-readable medium can include a machine-teachable module and a control module that are executable by the processor. The machine-teachable module can receive depth data and rate of drill bit penetration from one or more sensors in a drilling operation, and determine an estimated lithology of a formation at which the drill bit subsystem is located. The control module can use the estimated lithology to determine an updated location of the drill bit subsystem, and control a direction of the drill bit using the updated location and a drill plan.
(FR) Cette invention concerne un sous-système de trépan, comprenant éventuellement un trépan, un processeur et un support non transitoire lisible par ordinateur conçu pour stocker des instructions et être positionné en fond de trou avec le trépan. Les instructions du support non transitoire lisible par ordinateur peuvent comprendre un module d'apprentissage automatique et un module de commande qui sont exécutables par le processeur. Le module d'apprentissage automatique peut recevoir des données de profondeur et une vitesse de pénétration de trépan à partir d'un ou plusieurs capteurs lors d'une opération de forage, et déterminer une composition lithologique estimée d'une formation dans laquelle le sous-système de trépan est situé. Le module de commande peut utiliser la composition lithologique estimée pour déterminer un emplacement mis à jour du sous-système de trépan, et commander une direction du trépan à l'aide de l'emplacement mis à jour et d'un plan de forage.
