摘要

Wear sleeves and methods of using and installing such sleeves within a tubing hanger in a production wellhead assembly. A method includes positioning a wear sleeve around a polished rod and within a tubing hanger in a production wellhead assembly, the wear sleeve defining a production fluid passage. A wear sleeve includes: an outer part with pin threading sized to fit uphole facing box threading in an internal bore of a tubing hanger; an inner part defining a polished rod passage, the inner part comprising sacrificial material; a keyway defined on an uphole facing surface of one or both the outer part and the inner part; and a production fluid passage defined in use by one or more of the outer part or the inner part.
