Abstract

L'invention concerne un système de synchronisation de réseau de répéteurs de fond de trou pour un appareil de forage comprenant un train de tiges de forage s'étendant vers le bas sous la surface depuis une tête de puits de surface. Le système comprend un nud situé au niveau de l'extrémité inférieure du train de tiges de forage et comprenant un capteur conçu pour fournir un ensemble de données de signal correspondant à des conditions de forage de fond de trou. De multiples nuds sont situés en fond de puits entre l'assemblage de fond (BHA pour BottomHole Assembly) et la tête de puits et sont associés avec le train de tiges de forage. Les nuds sont adaptés pour recevoir et transmettre les signaux. Le système de commande de synchronisation est adapté pour commander à tous moments dans une trame temporelle selon des constantes pré-configurées connues de tous les nuds. L'invention concerne en outre un procédé de synchronisation de réseau de répéteurs linéaires à faible débit de fond de puits qui utilise le système.
