CA 2372355

An apparatus for use in a wellbore comprises a housing having a longitudinal axis and a mechanism having one or more impact elements adapted to move along the longitudinal axis in an oscillating manner to impart a back and forth force on the housing to vibrate the housing. In another arrangement, an apparatus for use in a wellbore comprises a housing and at least one impact element rotatably mounted in the housing. The at least one impact element is rotatable to oscillate back and forth to impart a vibration force to the housing.

Appareil à utiliser dans un puits de forage qui comprend un boîtier ayant un axe longitudinal et un mécanisme doté d'un ou de plusieurs éléments d'impact conçus pour se déplacer le long de l'axe longitudinal en oscillant pour communiquer une force de va-et-vient au boîtier et le faire vibrer. Dans un autre mode de réalisation, un appareil à utiliser dans un puits de forage comprend un boîtier et au moins un élément d'impact fixé de manière à pouvoir effectuer des mouvements de rotation dans le boîtier. L'élément d'impact est rotatif et effectue un mouvement de va-et-vient en oscillant pour communiquer une force de vibration au boîtier.
