发明名称 APPARATUS, SYSTEM AND METHOD FOR CIRCUMFERENTIALLY ORIENTING A DOWNHOLE LATCH SUBSYSTEM
摘要 <p>An apparatus for circumferentially orienting a downhole latch assembly in a wellbore. The downhole latch assembly has a plurality of latch keys including a primary latch key. The apparatus includes a casing string positionable in the wellbore. A window joint is interconnected in the casing string. A latch coupling having a latch profile is interconnected in the casing string downhole of the window joint. An orienting subassembly interconnected in the casing string has an orienting profile positioned uphole of the latch profile such that, after operable engagement of the primary latch key with the orienting profile, axial alignment of the latch assembly with the latch coupling causes operable engagement of the latch keys with the latch profile.</p>
