    Abstract: A packer includes a sealing element positioned at least partially around a tubular, the sealing element having an axial end, a gage ring positioned at least partially around the tubular and adjacent to the axial end of the sealing element, and a plurality of petals pivotally coupled to the gage ring, extending at least partially axial ly therefrom toward the sealing element, and positioned radially outwards of the axial end of the sealing element. The gage ring is movable axially along the tubular, towards the sealing element, such that the gage ring applies an axial force to the sealing element to expand the sealing element radially outwards, and the plurality of petals are configured to pivot radially outwards when the sealing element radially expands.

    Abstract: Downhole tools and methods, of which the downhole tool includes an expandable sleeve defining a bore therethrough, and a first body positioned at least partially within the bore of the expandable sleeve. The first body is slidable relative to the expandable sleeve, and sliding the first body along the bore of the expandable sleeve causes the expandable sleeve to radially expand so as to actuate the downhole tool from a run-in configuration to a set configuration. The downhole tool also includes an isolation device received at least partially in the expandable sleeve in the set configuration. A pressure on the isolation device is at least partially transmitted to the expandable sleeve as a radially-outward force.

    Abstract: A downhole tool includes a sealing element configured to expand radially outwards to form a seal with a surrounding tubular, a cone defining a tapered surface, and a slips assembly comprising a plurality of slips. The slips assembly is receivable at least partially around the cone, such that moving the cone in an axial direction with respect to the slips assembly causes the plurality of slips to separate circumferentially apart. The tool also includes a backup member positionable at least partially around the tapered surface of the cone and positioned adjacent to the slips assembly. The backup member is configured to break as the cone is moved toward the plurality of slips, to prevent the sealing element from extruding between circumferentially- adjacent slips of the plurality of slips.

    Abstract translation: 井下工具包括构造成径向向外膨胀以与周围管形成密封的密封元件,限定锥形表面的锥体和包括多个卡瓦的卡瓦组件。 卡瓦组件可至少部分地容纳在锥体周围,使得相对于卡瓦组件在轴向方向上移动锥体导致多个卡瓦周向分离。 该工具还包括支撑构件,该支撑构件可至少部分地定位在锥体的锥形表面周围并定位在滑动组件附近。 支撑构件被构造成当锥体朝向多个卡瓦移动时破裂,以防止密封元件在多个卡瓦的周向相邻的卡瓦之间挤出。
