Abstract (en)
[origin: WO2011037584A1] 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).
