Abstract: A sealing element is flanked by wedge-shaped extrusion ring assemblies. The extrusion rings are continuous for 360 degrees and are slotted from the outside dimension and alternatively from the inside dimension to allow the diameter to increase to the surround tubular or open hole. The extrusion rings climb a ramp on an adjacent pedestal ring on the way out to the borehole wall. Depending on the dimension of the gap to be spanned the extrusion ring slides a variable distance up the pedestal ring ramp. An optional anchor ring is initially forced up an opposite ramp of the pedestal ring. If the sealing gap is short the anchor ring can be eliminated. For larger gaps the anchor ring moves out far enough toward the borehole wall to contact the extrusion ring located on an opposing ramp of the pedestal ring so that reaction forces are directed to keep the anchor ring wedged in position for support of the extrusion ring assembly.

Abstract translation: 密封元件的侧面是楔形挤出环组件。 挤压环是连续的360度，并且从外部尺寸开始，或者从内部尺寸开始，以允许直径增加到环绕的管状或开孔。 挤出环在通往钻孔壁的路径上爬上相邻基座环上的斜坡。 根据要跨越的间隙的尺寸，挤压环在基座环坡道上滑动一段不等的距离。 一个可选的锚环最初被强制上升到底座环的一个相反的斜坡上。 如果密封间隙较短，则可以取消锚环。 对于较大的间隙，锚环远离钻孔壁足够远以接触位于基座环的相对坡道上的挤压环，从而引导反作用力以将锚环楔入适当位置以支撑挤压环组件。

Abstract: The invention provides an expanding and collapsing ring apparatus (171) and method of use. The expanding and collapsing ring comprises a plurality of elements (177) assembled together to form a ring structure (172, 173a, 173b) oriented in a plane around a longitudinal axis. The ring structure is operable to be moved between a collapsed condition and a first expanded condition by movement of the plurality of elements on actuation by an axial force. The apparatus further comprises a secondary expanding and collapsing mechanism operable to move the ring structure between its collapsed condition or its first expanded conditions to a second expanded condition on actuation by an axial force. Applications of the invention include oilfield devices, including anti-extrusion rings, plugs, packers, locks, patching tools, connection systems, and variable diameter tools run in a wellbore.

Abstract: A sealing element is flanked by wedge-shaped extrusion ring assemblies. The rings climb a ramp on an adjacent pedestal ring on the way out to the borehole wall. Depending on the dimension of the gap to be spanned the extrusion rings slide part way up the pedestal ring ramp or to the top of the pedestal ring. An anchor ring is initially forced up an opposite ramp of the pedestal ring. If the sealing gap is short the anchor ring touches the borehole wall to act as an anchor for the plug while remaining spaced apart from the extrusion ring assembly. For larger gaps the anchor ring moves out far enough to the borehole wall and in contact with the extrusion ring located on top of the pedestal so that reaction forces are directed to keep the anchor ring wedged in position for support of the extrusion ring assembly.

Abstract: A packer has a swellable element and has end rings and compressible elements at each end of the swellable element. The packer may be first set using internal bore pressure to compress one of the compressible elements against one of the end rings with a first hydraulic setting mechanism. The packer may then be set a second time using annulus pressure to compress against the other compressible element with a second hydraulic setting mechanism. Either way, the compressible elements are compressed to expand out to the borehole and to limit extrusion of the swellable element outside the compressed elements.

Abstract: Downhole tool packing element systems comprise a sealing element having a support system. The support system can include one or more of a first spacer ring, a second spacer ring, a third spacer ring, a mesh ring, and one or more petal rings. One or more of these components can be disposed at one or both of the upper end and/or lower end of the sealing element. When compressed, the sealing element is moved radially outward to engage an inner wall surface of a wellbore due to compressive forces of the one or more spacer ring(s), mesh ring, and/or petal ring(s). In certain embodiments, the lower end of one or more of the mesh ring(s) and/or petal ring(s) rotate outwardly toward the casing and, in certain embodiments, engage the casing to facilitate creation of the seal.
