DIRECTIONAL SENSOR SYSTEM COMPRISING A SINGLE AXIS SENSOR ELEMENT POSITIONED AT MULTIPLE CONTROLLED ORIENTATIONS

摘要

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.
