Abstract

La présente invention se rapporte à un système permettant d'exécuter une opération appropriée dans un puits de forage au moyen d'un résonateur (74). Ledit système comporte un résonateur (74) conçu pour générer des impulsions d'énergie mécanique, un dispositif d'engagement (92) conçu pour engager de manière sure un objet à l'intérieur du puits de forage et un capteur (68a) destiné à détecter la réponse de l'objet aux impulsions générées par le résonateur (74). Ledit résonateur (74) est placé en un point approprié du puits de forage et le dispositif d'engagement (92) est fixé à l'objet. On actionne le résonateur (74) à une fréquence appropriée à la génération d'impulsions susceptibles de pénétrer ledit objet. Le capteur (68a) détecte la réponse de l'objet aux impulsions ainsi induites et produit une information utilisée pour ajuster la fréquence de fonctionnement. Ledit système, mis en oeuvre suivant différentes configurations, peut servir à repêcher et à libérer un train de tiges bloqué, à faciliter le perçage de puits et à exécuter une opération de cimentation. Un circuit de commande (78) gère le fonctionnement du système conformément à des instructions programmées.
