发明名称 High pressure wellhead assembly interface
摘要 A wellhead assembly with high pressure interface is provided. The wellhead assembly includes a tubing spool that connects the wellhead to a BOP and a casing hanger that is landed in the wellhead and connected thereto. The wellhead assembly further includes a gasket that is disposed between opposing ends of the tubing spool and casing hanger. A connector engages the wellhead and tubing spool forcing the opposing ends of the tubing spool and casing hanger together, which thereby applies a compressive load to the gasket, which in turn forms a fluid tight seal therebetween.
