SHOCK AND VIBRATION ENVIRONMENTAL RECORDER FOR WELLBORE INSTRUMENTS

摘要

A wellbore instrument includes a housing configured to traverse a subsurface wellbore. A shock and vibration sensor disposed in the housing and is mounted on a carrier disposed in the housing. The carrier includes at least two, laterally movable elements each having an outer surface configured to contact an inner surface of the housing. The carrier includes an adjustable wedge disposed between the opposed elements. The wedge is arranged such that longitudinal movement thereof causes lateral separation of the laterally movable elements into frictional engagement with the inner surface of the housing.
