CONTINUOUSLY SEALING TELESCOPING JOINT HAVING MULTIPLE CONTROL LINES

摘要

A telescoping joint is provided with one or more control lines and is usable for landing a subsea tubing hanger. The telescoping joint can include an inner mandrel, an outer mandrel, a seal between the inner mandrel and the outer mandrel, and a coiling chamber. The outer mandrel is controllably releasable from the inner mandrel by a release mechanism. The seal is sealably engaged with the outer mandrel for continuously sealing an inner area defined by the inner mandrel from a wellbore environment exterior to the telescoping joint as the outer mandrel axially moves relative to the inner mandrel. A control line is coiled in the coiling chamber and the coiling chamber is axially positioned between the release mechanism and the seal.
