Title (EN) SINGLE SENSOR ELEMENT POSITIONED IN MULTIPLE CONTROLLED ORIENTATIONS
(FR) SYSTEME DE CAPTEUR DIRECTIONNEL COMPRENANT UN ELEMENT DE CAPTEUR MONOAXIAL QUI EST PLACE SELON PLUSIEURS ORIENTATIONS CONTROLEES
Abstract:
(EN) A directional sensor system (10) that incorporates a single axis sensor (14) element that is manipulated to a plurality of orientations. The resulting responses of the sensor element at these locations are combined to obtain a measure of orientation (22) of the system. The system applicable for determining orientation of instrumentation within a well borehole (67) such as measurement-while-drilling, wireline and tubing conveyed borehole instrumentation. The system can be used in other subsurface and surface applications.
(FR) La présente invention concerne un système de capteur directionnel comprenant un élément de capteur monoaxial qui est manipulé selon plusieurs orientations. Les réponses résultantes de l'élément de capteur à ces emplacements sont combinées afin d'obtenir une mesure de l'orientation du système. Cette invention concerne également le système qui peut être appliqué pour déterminer l'orientation des instruments dans un puits de forage, par exemple des instruments de fond de mesure en cours de forage, transportés par câble métallique et par colonne de production. Le système peut être utilisé dans d'autres applications souterraines et de surface.
