Integrated electrical connector for use in a wellhead tree

摘要

A subsea wellhead assembly 5 provided on a borehole 3, the assembly comprising a tree 7, tubing or tubular stab member 42 extending into the borehole, casing 25 circumscribing the tubing to form an annulus 26 therebetween, a borehole device 46, an annular member 30 having a bore 48, an electrically conductive member 36 disposed in the bore 48, connections 32, 38 comprising an a annular ring connectable with a ring contact and a feed member 44 in communication with the borehole device. A tubing hanger 21 may be provided, a passage in the tree having an electrically conductive feed line 34 may be in communication with a remotely located control facility. The connectors may comprise a gallery ring wet connect. The assembly allows for a data sensor circuit for transmitting sensed data from within a wellbore to the well surface. The circuit includes a signal conduit axially inserted within the wall of a stab unit with connectors at the top and bottom portions of the stab unit. Corresponding connection leads are included within the wellhead assembly to connect with the stab unit connectors.
