摘要： Subsea wellhead apparatus is disclosed in which a hanger is adapted to be lowered into and landed in a predetermined orientational and longitudinal position within the bore of a wellhead housing installed on a subsea well in order to suspend a tubing string within the well bore. The hanger has a passageway with one adapted to connect with a tube extending downwardly into the well bore for connection with an operator for a subsurface safety valve in the tubing string, and another end which connects with the outer side of the hanger opposite the bore of the housing. The housing has a passageway therethrough with one end in general alignment with the other end of the passageway in the hanger to form a continuation thereof when the hanger is landed in the housing. A body on the outer side of the housing has passageway means with one end in general alignment with the other end of the housing passageway and another end for connection with a control line external to the housing. Flow of control fluid to and from the valve operator is controlled by a valve which includes a closure member in the hanger passageways position to be opened by the inner end of a stem mounted in the body for longitudinal reciprocation within the housing passageway to open the valve and hold it open so as to form a confined flow path between the hanger passageway and the passageway means in the body which connects with the control line.

摘要： There are disclosed a wellhead system and a method for use in drilling a subsea well from a jackup platform which includes a wellhead housing which is installed on a surface casing of a subsea well. A first riser having a connector on its lower end is lowered over the upper end of the housing as the connector to land on the housing, and a second riser is lowered through the first riser and connector over and onto the upper end of the wellhead housing to form an upward continuation of the bore of the housing. The connector has locking parts which are movable between outer unlocking position to permit the second riser to be lowered onto and raised from the wellhead housing, and inner positions for locking engagement with the upper end of the housing and lower end of the second riser. A casing hanger is lowered through the second hanger and into landed position within the housing bore for suspending an inner casing string within the surface casing.

摘要： There is disclosed a wellhead connector for connecting first and second tubular wellhead members in end-to-end relation, wherein locking segments are carried by a ring about the first member for movement between an outer position, to permit the ring to be moved over an outer surface of the second member, to an inner position in which locking shoulders on the inner ends of the locking segments slidably engage a locking shoulder about the outer surface of the second member to urge the ends of the members into tight engagement. The locking segments are moved to their inner positions by means of wedges guidably movable in the ring outwardly of the locking segments and having surfaces slidable over surfaces on the outer ends of the segments as the wedges are moved toward one another, and are moved to their outer positions, as the wedges move away from one another, by means of coil springs acting between the body and locking segments.
