    • An apparatus and method for radially expanding and plastically deforming a tubular member. The apparatus includes a support member, an expansion device coupled to the support member and at least one of a cutting device coupled to the support member, an actuator coupled to the support member, a sealing assembly, or a packer assembly coupled to the support member. The apparatus may further include a gripping device for coupling the tubular member to the support member. The expansion device may be used for radially expanding and plastically deforming the tubular member which may be coupled to the support member. The cutting device may be used for cutting the tubular member. The actuator may be used for displacing the expansion device relative to the support member. The sealing assembly may be used for sealing an annulus defined between the support member and the tubular member.
    • 一种用于使管状构件径向膨胀和塑性变形的装置和方法。 该装置包括支撑构件,联接到支撑构件的膨胀装置和联接到支撑构件的切割装置中的至少一个,联接到支撑构件的致动器,密封组件或联接到支撑构件的封隔器组件 。 该装置还可以包括用于将管状构件联接到支撑构件的夹紧装置。 膨胀装置可以用于径向膨胀并使管状构件塑性变形,管状构件可联接到支撑构件。 切割装置可以用于切割管状构件。 致动器可用于相对于支撑构件移动膨胀装置。 密封组件可用于密封限定在支撑构件和管状构件之间的环空。

    • An apparatus (100) for installing a liner string (102) in a wellbore casing (40). The apparatus (100) includes a tubular mandrel subassembly (110), a load transfer subassembly (140) and an expander cone subassembly (142). The load transfer subassembly (140) is carried on the tubular mandrel subassembly (110) and is operable to apply a force in the downhole direction to the liner string (102). The expander cone subassembly (142) is carried on the tubular mandrel subassembly (110) and is operable to radially expand at least a portion of the liner string (102) into contact with the wellbore casing (40) when axially moved through the liner string (102). In operation, decoupling of the load transfer subassembly (140) from the tubular mandrel subassembly (110) enables release of the apparatus (100) from the liner string (102).
    • 一种用于将衬管串(102)安装在井筒壳体(40)中的装置(100)。 装置(100)包括管状心轴子组件(110),负载转移子组件(140)和膨胀锥组件组件(142)。 负载转移子组件(140)被承载在管状心轴子组件(110)上,并且可操作以向井筒线(102)施加井下方向的力。 膨胀锥体子组件(142)承载在管状心轴子组件(110)上,并且可操作以在轴向移动穿过衬管柱时径向膨胀衬套线(102)的至少一部分与井筒壳体(40)接触 (102)。 在操作中,负载转移子组件(140)与管状心轴子组件(110)的分离使得能够从衬套线(102)释放设备(100)。
