CA 2649570

A method for conducting nondestructive internal inspection of a rotary drill bit used for drilling subterranean formations comprises communicating ultrasonic waves into a drill bit and detecting ultrasonic waves that are reflected by at least a portion of the drill bit. In some embodiments, the waves may be directed into the drill bit from within a longitudinal bore thereof. Reflected waves also may be detected from within the bore. The methods may be used to develop threshold acceptance criteria for classifying drill bits as acceptable or unacceptable to prevent catastrophic failures of drill bits during use. Systems and apparatuses are disclosed for conducting nondestructive ultrasonic inspection of a drill bit used for drilling subterranean formations. The systems and apparatuses may comprise an ultrasonic probe configured for insertion within an internal longitudinal bore of a drill bit. Drill bits are disclosed that are configured to facilitate nondestructive ultrasonic inspection thereof.

Technique d'inspection interne non destructrice appliquée à un outil de forage rotatif utilisé dans des formations souterraines, consistant à envoyer des ondes utrasonores dans un outil de forage et à détecter les ondes ultrasonores réfléchies par au moins une partie de l'outil. Dans certains modes de réalisation, les ondes peuvent être dirigées vers l'intérieur de l'outil de forage dan un conduit interne de ce dernier. Ces techniques peuvent s'utiliser pour élaborer des critères d'acceptation de seuil permettant de classer les outils de forage comme acceptables ou non acceptables et d'empêcher la survenue de défaillances catastrophiques de l'outil en cours d'utilisation. L'invention concerne également des systèmes et des dispositifs permettant d'exécuter des inspections par ultrasons non destructrices d'outils de forage utilisés pour forer dans des formations souterraines. Ces systèmes et dispositifs reposent sur l'emploi d'une sonde destinée à être introduite dans un conduit longitudinal interne d'un outil de forage. Sont également décrits des outils de forage conçus pour faciliter l'inspection ultrasonique non destructrice.
