Abstract

Die Erfindung betrifft eine Meßvorrichtung 41 zum Bestimmen der Ausrichtung und des Verlaufs eines Bohrgestänges 11 in einem Bohrloch. Die Meßvorrichtung umfaßt einen Sondenkörper 21, in dem eine Mehrzahl von Neigungssensoren 22 in Längsrichtung verteilt fest eingebaut ist, wobei der Sondenkörper 21 in seiner Längsrichtung zumindest um den Betrag der Längserstreckung der Neigungssensoren 22 verschiebbar ist.The invention relates to a measuring device 41 for determining the orientation and the course of a drill string 11 in a borehole. The measuring device comprises a probe body 21, in which a plurality of inclination sensors 22 are fixedly mounted distributed in the longitudinal direction, wherein the probe body 21 is displaceable in its longitudinal direction at least by the amount of the longitudinal extension of the tilt sensors 22.
