摘要
To provide for accurate determination of azimuth in a borehole survey apparatus, a downhole probe is provided with two or more sections connected by torsionally rigid, flexible joint assemblies with provisions for generating signals that represent the relative inclination and azimuth of one probe section from another. These signals are combined with inclination signals obtained from a set of accelerometers in one of the probe sections in a signal processing unit to generate signals that represent the direction and depth of the borehole.
