Title
(EN) WELL CONSTRUCTION CONTROL SYSTEM
(FR) SYSTÈME DE COMMANDE DE CONSTRUCTION DE PUITS
Abstract
(EN)
Apparatus and methods for a well construction system and a well site control system. The construction system is for forming a wellbore at an oil and gas well site. The construction system includes rig and well pressure control systems. The rig control system is for selectively moving a drill string within the wellbore, and includes a first actuator for actuating at least a portion of the rig control system. The well pressure control system is for controlling pressure within the wellbore, and includes a second actuator for actuating at least a portion of the well pressure control system. The well site control system is communicatively connected with the first and second actuators, and is operable to generate first and second control signals to operate the first and second actuators, respectively. The first control signal is determined based on the computer program code and the second control signal

La présente invention concerne un appareil et des procédés pour un système de construction de puits et un système de commande de site de forage. Le système de construction est destiné à former un puits de forage à un site de forage de pétrole et de gaz. Le système de construction comprend des systèmes de commande de pression de forage et d'appareil de forage. Le système de commande d'appareil de forage est destiné à déplacer sélectivement un train de tiges de forage à l'intérieur du puits de forage, et comprend un premier actionneur pour actionner au moins une partie du système de commande d'appareil de forage. Le système de commande de pression de puits est destiné à commander la pression à l'intérieur du puits de forage, et comprend un second actionneur pour actionner au moins une partie du système de commande de pression de puits. Le système de commande de site de forage est connecté en communication avec les premier et second actionneurs, et est utilisable pour générer des premier et second signaux de commande pour actionner les premier et second actionneurs, respectivement. Le premier signal de commande est déterminé sur la base du code de programme d'ordinateur et du second signal de commande.
