    • Methods and apparatus create an attachment and a seal between two tubular members in a wellbore. An expandable assembly includes a packer and liner hanger to be expanded into a surrounding tubular. The packer can be a longitudinally corrugated packer and can have a sealing element disposed on an outer surface thereof. The liner hanger can include a plurality of formations extending outward along an outer surface of the liner hanger to form interspaces for longitudinal fluid flow between the formations. In operation, an expansion tool moves axially through an inner diameter of the expandable assembly to expand the liner hanger with a fluted expander and subsequently the packer with a substantially uniform outer diameter cone.
    • 方法和装置在井筒中的两个管状构件之间形成附件和密封。 可膨胀组件包括封隔器和衬垫悬挂器,以扩展成围绕的管状件。 封隔器可以是纵向波纹封隔器,并且可以具有设置在其外表面上的密封元件。 衬管悬挂器可以包括沿着衬管悬挂器的外表面向外延伸的多个结构,以形成用于在地层之间纵向流体流动的间隙。 在操作中,膨胀工具轴向移动通过可膨胀组件的内径,以用​​带凹槽的膨胀机和随后的具有基本均匀的外径锥体的封隔器来扩展衬套。
