    摘要： An anchor assembly (400) for anchoring a downhole tool in a wellbore tubular. The anchor assembly (400) includes a plurality of slip arm assemblies each having first and second arms (412, 414) hingeably coupled together. The first and second arms (412, 414) each have teeth (418, 426) on one end. A first sleeve (402) is rotatably associated with each of the first arms (412) and a second sleeve (404) is rotatably associated with each of the second arms (414) such that the anchor assembly (400) has a running configuration in which the slip arm assemblies are substantially longitudinally oriented and an operating configuration in which the first and second arms (412, 414) of each slip arm assembly form an acute angle relative to one another such that the teeth (418, 426) of the first and second arms (412, 414) define the radially outermost portion of the anchor assembly (100).

    摘要： A compression assembly (500) for actuating packing elements of a through tubing bridge plug in a casing string of a wellbore. The compression assembly (500) includes a support assembly (502) and an anti extrusion assembly (504). The support assembly (502) has a running configuration in which link arm assemblies are substantially longitudinally oriented and an operating configuration in which short arms (514) are pivoted relative to long arms (520) of link arm assemblies such that the short arms (514) form a support platform. The anti extrusion assembly (504) is operably associated with the support assembly (502). The anti extrusion assembly (504) has a running configuration in which petals (536) are substantially perpendicular to a base member (534) and nested relative to one another and an operating configuration in which the petals (536) are radially outwardly disposed substantially filling gaps between the short arms (514).

    摘要： A through tubing bridge plug (200) for providing a gripping and sealing engagement with a casing string of a wellbore. The bridge plug (200) includes an actuation rod (208), an anchor assembly (212), a pair of compression assemblies, each including a support assembly (216, 242) and an anti extrusion assembly (220, 238) and a packing assembly (224) disposed about the actuation rod (208) between the compression assemblies. Responsive to longitudinal movement of the actuation rod (208), the anchor assembly (212) establishes the gripping engagement with the casing string, the compression assemblies are radially deployed such that the anti extrusion assemblies (220, 238) are supported by the support assemblies (216, 242) and the packing assembly (224) establishes the sealing engagement with the casing string.
