WELLHEAD ASSEMBLY WITH TUBING TENSIONING MEANS |
摘要 |
A tubing string (86) is connected at its upper end to a hanger (42) and has its lower end anchored within an outer casing. The hanger and tubing string are lifted from a position below the wellhead assembly to tension the tubing string a desired amount. The hanger has a plurality of guide pins (90) extending from and spaced about the outer periphery of the hanger. Upon lifting of the hanger and suspended tubing string, the guide pins enter inverted J-slots (62) in the hanger bowl (30) which receive and guide the pins to a seated position on the bowl. |
