Tubing head
Tubing head is installed between Christmas tree and casing head and hung on pipeline post in the well. It seals the annular space of pipeline and oil casing, It provides control channel for safety valve in the well, also provide through channel for electric pump and cable. It could complete injection balance fluid and washing well through two side outlets (linking casing valve) of tubing head spool. The function of top wire is locking pipeline pillar to prevent pressure in the well ejecting pipeline pillar, the connecting type of side outlet is bolted flange with LP thread for valve-replacement operation. In the bottom flange sets secondary sealed mechanism and sealing tests point. The tubing head can be set with BPV thread as required.
