摘要： A wellhead completion assembly has a head connected to surface casing. A rotatable flange or the like can be used to connect various components to a threaded end of the head. A casing hanger installs in the head, and the hanger's upper end extends beyond the head's top edge. This exposed end has an external threaded connection to connect to various wellhead components using a rotatable flange or the like. For example, a locking ring can threadably connect to the head's threaded end to support the hanger in the head. Then, a rotatable flange can threadably connect to the hanger's exposed end so that another component, such as a completion spool or gate valve, can nippled up directly to the hanger. When the hanger is fluted, a pack-off assembly can allow testing off inner and outer sealing integrity via a test port accessible through an opening in the locking ring.

摘要： A rotating breech lock rotates tubing to distribute wear caused by a rotating or reciprocating rod of an artificial lift system. The rotating breech lock has a spool that disposes on a wellhead. A bowl element disposes in the spool's bore, and a hanger fits into the spool and lands on the bowl element with a thrust bearing. Above the hanger, a load ring fits against the hanger with a bearing, and a hold-down sleeve and locking pins hold the load ring against the hanger. The spool has a worm that mates with a wheel defined about the hanger so turning the worm by a ratchet or other mechanism rotates the hanger. Internally, the hanger has a bore with opposing shoulders separated by gaps. A mandrel couples to the tubing and disposes up into the hanger. Protrusions or keys on the hanger can selectively align with the gaps and the shoulders depending on how the mandrel is rotated in the hanger bore.
