METHOD AND APPARATUS FOR REMOTE CONTROL OF A TUBING EXIT SLEEVE

摘要

A remote-controlled tubing sleeve window (204) for access to a lateral wellbore (112) of a multilateral well (100). The tubing sleeve window (204) has a tubular body portion (202) that defines a side port (212) that is sufficiently-sized to allow a well tool to pass. A sleeve (204) is received in the tubing body portion (202) such that it can reciprocate within the body portion (202). The sleeve (204) is responsive to a remote command such that a side window defined in the sleeve (204) can be substantially-aligned with the side port (212) in an open relation such that a well tool can pass through said substantially-aligned side window and side port (212). A position sensor (238) is also provided to sense a displacement of the sleeve (204) with respect to the body portion (202).
