SELF-DEFLECTING MULTILATERAL JUNCTION

机译:自我偏转多边交界处

摘要

Provided is a self-deflecting multilateral junction, a method, and a well system. The self-deflecting multilateral junction, in one aspect, includes a deflection device having an uphole end and a downhole end, the deflection device including a main tubular, a first flow path off the main tubular and operable to couple to a wellbore, a second flow path off the main tubular and operable to couple to a lateral wellbore, the second flow path having a lateral seal bore, and a deflecting ramp. The self-deflecting multilateral junction, according to this aspect, further includes a lateral stinger positioned within the main tubular and releasably coupled to the deflection device, the lateral stinger including a nose end configured to extend into the second flow path, a valve member, and a lateral seal for engaging the lateral seal bore.
