发明名称 LINER HANGER ASSEMBLY
摘要 A liner hanger assembly is disclosed for setting within a casing conduit and carrying a liner string therebelow. The assembly has slip elements for gripping the casing with each of the slip elements having symmetrically angled teeth such that only one set of slips may be used to anchor the hanger and liner in position against relative longitudinal movement in either direction subsequent to setting. The apparatus is hydraulically settable and provides for application of workstring load to the apparatus to direct additional load in excess of that required to set the slips in anchoring engagement. The housing of the apparatus and the liner therebelow also may be rotated by the tubular workstring subsequent to setting without effecting rotational movement of the slip elements.
