Sleeve apparatus, downhole system, and method
摘要:
A sleeve apparatus having a longitudinal axis and an interior further includes a tubular having a plurality of ports providing a length of fluidic access between the interior and an exterior of the tubular, the length measured with respect to the longitudinal axis; and, a sleeve disposed within the tubular and configured to move longitudinally with respect to the longitudinal axis. The sleeve further has a plurality of apertures misaligned with the plurality of ports in a closed condition of the sleeve apparatus and at least substantially aligned with the plurality of ports in a fully open condition of the sleeve apparatus, and a plurality of non-apertured sections aligned with the plurality of ports in the closed condition. A longitudinal shifting distance of the sleeve to move the sleeve apparatus from the closed condition to the fully open condition is less than the length of fluidic access.
