AZIMUTHAL ALIGNMENT OF GYROINKLINOMETERS FOR ARBITRARY ORIENTATION WELLS WITH GPS-COMPASS
Read the full article
Various variants of an initial azimuthal alignment of gyroinklinometer from independent gyrocompassing up to external course pointing with application of satellite navigating devices are analyzed. Lacks of existing methods of an initial alignment and an opportunity of their elimination are shown at transition on external course pointing. The opportunity of realization of an initial alignment by means of GPS-compasses is considered and the constructive decision for device bases binding is offered.
