An apparatus for estimating at least one of a dynamic motion of a portion of interest of a drill string and a static pa-rameter associated with the portion of interest, the apparatus having: a plurality of sensors operatively associated with the drill string at at least one location other than the portion of interest; and a processing system coupled to the plurality of sensors, the processing system configured to estimate at least one of the dynamic motion and the static parameter using a measurement from the plurality of sensors as input.
L'invention concerne un appareil destiné à estimer un mouvement dynamique dune portion dintérêt dune colonne de forage et / ou un paramètre statique associé à la portion dintérêt, lappareil comprenant : une pluralité de capteurs associés fonctionnellement à la colonne de forage au niveau dau moins un emplacement autre que la portion dintérêt ; et un système de traitement couplé à la pluralité de capteurs, ledit système de traitement étant configuré de façon à estimer le mouvement dynamique et / ou le paramètre statique en utilisant comme donnée dentrée une mesure provenant de la pluralité de capteurs.
