    • A flow control apparatus (800) includes a tubular member (818) having a plurality of openings (820, 822, 824, 826) that allow fluid flow between an exterior and an interior flow path (828) of the tubular member (818) and a multi-stage flow restricting section (804) operably positioned in a fluid flow path between a fluid source disposed exteriorly of the tubular member (818) and the interior flow path (828). The flow restricting section (804) including a plurality of flow restricting devices (838, 844, 850) each operable to create a pressure drop. Actuatable devices (830, 832, 834, 836) operably associated with the openings (820, 822, 824, 826) are sequentially actuatable to allow fluid flow through the associated openings (820, 822, 824, 826), thereby sequentially reducing the pressure drop experienced by fluids flowing from the fluid source to the interior flow path (828).
    • 流量控制装置(800)包括具有允许流体在管状构件(818)的外部流动路径(828)与内部流动路径(828)之间流动的多个开口(820,822,824,826)的管状构件(818) 以及多级流动限制部分(804),其可操作地定位在布置在管状部件(818)外部的流体源与内部流动路径(828)之间的流体流动路径中。 包括多个流量限制装置(838,844,850)的流量限制部分(804)各自可操作以产生压降。 可操作地与开口(820,822,824,826)可操作地关联的可致动装置(830,832,834,83​​6)可顺序致动以允许流体流过相关联的开口(820,822,824,826),由此依次减小 流体从流体源流向内部流动路径(828)的压降。
