摘要
A rotary drilling apparatus for drilling deviated wellbores Is disclosed that in one embodiment includes a drilling assembly that further includes a drilling motor coupled to a drive member to rotate a disintegrating device, a housing outside the drive member having a lower section and an upper section, and a steering device disposed outside the drive member that tilts the lower section relative to the upper section and maintains the tilt geostationary or substantially geostationary when the drilling assembly is rotating to drill a deviated section of the wellbore.
