发明名称 INTERNAL LOCKDOWN SNUBBING PLUG
摘要 A snubbing plug is configured to be secured within a component of a mineral extraction system by an internal locking mechanism. In addition, the snubbing plug enables pressure equalization of regions above and below the plug before removal of the plug. Upon insertion of the snubbing plug into a well component, pressure may be equalized via fluid pathways through the snubbing plug. The pathways are sealed closed during snubbing operations and opened again when snubbing operations are complete. Manipulation of the fluid pathways may be accomplished via rotation of a load ring within the snubbing plug.
