摘要： There is disclosed an expandable seal for sealing at least part of a wall of a well borehole, an expandable seal assembly comprising at least two such expandable seals, and a method of sealing at least part of a well borehole using such a seal. In one embodiment, the expandable seal (32) comprises an expandable tubular support member (34) and an inflatable seal element (36) mounted externally of the expandable tubular support member (34) for inflation radially outwardly into sealing engagement with at least part of a wall (50) of a well borehole (10). There is also disclosed a sealing apparatus for sealing at least one flow port in an expandable downhole tubular, in one embodiment, the sealing apparatus (332) comprising a sealing member (384) coupled to an expandable tubular (334), the sealing member (384) including a deformable portion (387) movable between a closed position preventing fluid flow through a flow port (356) and an open position permitting fluid flow through the flow port (356).
摘要翻译：公开了一种用于密封井眼的壁的至少一部分的可膨胀密封件，包括至少两个这种可膨胀密封件的可膨胀密封组件，以及使用这种密封件密封井眼的至少一部分的方法。在一个实施例中，可膨胀密封件（32）包括可膨胀管状支撑构件（34）和可膨胀密封元件（36），其可安装在可膨胀管状支撑构件（34）的外部，用于径向向外膨胀以与至少部分井眼（10）的壁（50）。还公开了一种用于密封可膨胀井下管中的至少一个流动口的密封装置，在一个实施例中，密封装置（332）包括联接到可膨胀管（334）的密封构件（384），密封构件 384）包括可在封闭位置之间移动的可变形部分（387），该封闭位置防止流过流动端口（356）的流体流动和允许流体流过流动端口（356）的打开位置。
