Concentric tubing hanger

摘要

A subsea well assembly has guides for orienting electrical connectors located on a concentric tubing hanger and on the tree. The guides use a guide slot and key to rotate the electrical connectors on the lower end of the tree when the tree is installed on the wellhead. The tree electrical connectors are located on the upper guide member and rotate relative to the tree as the guide slot engages the guide key. An annulus valve in the tubing hanger uses a sleeve with inner and outer metal seal lips.
