发明名称 Multilateral well drilling and reentry system and method
摘要 A system and method are disclosed for forming and reentering multiple lateral wells through a wall of a common well bore. The system includes an anchor, an orienting member, an extension member, a diverter and a probe releasably connected by one or more unilateral connections and a multilateral connection. The unilateral connection restricts rotational and translational movement of the system upon makeup, and maintains alignment between components thus joined in a single direction. The multilateral connection also restricts rotational and translational movement of the system upon makeup, however, enables alignment between components thus joined in multiple directions. Thus, use of the system enables lateral orientation of the diverter at multiple positions, positioning the diverter at multiple longitudinal positions and selective reentry of each lateral well formed.
