摘要： A subsea wellhead comprises a generally cylindrical body including a lower extension (9) for forming an annular space (11) for a cement column between the lower extension and an outer conductor. The extension carries a multiplicity of interfitting rings (13b) forming a sleeve which facilitates the flexure of the extension in the presence of the cement column. Each ring may comprise an inner flange for disposition adjacent the outside of the extension and an outer flange for fitment over the inner flange of an adjacent ring. The outer flange may have a radial through-bore.

摘要： Pressure relief devices comprise a chamber having a piston disposed therein. One side of the piston defines a hydrostatic chamber in fluid communication with an outside environment, such as an isolated wellbore annulus, through a port. The other side of the piston defines a sealed or isolated chamber. The pressure relief device permits changes in pressure in the isolated wellbore annulus to be distributed into the chambers so as to either reduce the pressure within the isolated wellbore annulus or increase the pressure within the wellbore annulus, both of which lessen the likelihood that the change in pressure within the isolated wellbore annulus will damage wellbore components disposed therein.
摘要翻译：减压装置包括其中设置有活塞的腔室。活塞的一侧限定通过端口与外部环境（例如隔离的井眼环空）流体连通的流体静力学室。活塞的另一侧确定了一个密封或隔离的腔室。泄压装置允许将分离的井筒环空中的压力变化分配到各个室中，从而减小隔离的井筒环空内的压力或增加井筒环空内的压力，这二者都减少了在隔离的井筒环空内的压力将损坏设置在其中的井筒部件。

摘要： An expandable packer tool comprising a mandrel tool body; a sleeve-like packer element mounted on the tool body; and a setting mechanism that is operable to axially compress the packer element such that the diameter of the packer element in its compressed state is increased compared to it uncompressed state. An extrusion barrier can comprise a ring of seal elements disposed around the tool body on either side of the packer element, and arranged to engage the packer element so that expansion of the packer element causes the ring of seal elements to expand in a corresponding manner so as to form an extrusion barrier; wherein the ring of seal elements comprises wedge-shaped seal members comprising first seal members having a inner base wider than an outer surface, and second seal members having an inner base narrower than an outer surface, the ring comprising alternating first and second members, the inclined faces of each wedge-shaped member engaging the corresponding faces of adjacent members. A retraction mechanism for the packer element comprises a cut-out in its inner surface near at least one end; and the setting mechanism comprises an inner mandrel that has an outward projection that engages in the cut-out so that the inner mandrel can exert a pulling force on the packer element.

摘要： A subsea well safing method and apparatus adapted to secure a subsea well in the event of a perceived blowout in a manner to mitigate the environmental damage and the physical damage to the subsea wellhead equipment to promote the ability to reconnect and recover control of the well. The safing assembly is adapted to connect the marine riser to the BOP stack. Pursuant to a safing sequence, the well tubular is secured in the upper and lower safing assemblies and the tubular is then sheared between the locations at which it as been secured. Subsequently, an ejection device is actuated to physically separate the upper safing assembly and connected marine riser from the lower safing assembly that is connected to the BOP stack.

摘要： A subsea wellhead assembly includes a wellhead body (1) which disposed to support an isolation sleeve (39) for a production tree and to support below the isolation sleeve a production casing hanger (21) for a production casing string. The body also supports a second casing string outside the production casing string whereby to form an annulus (22) between the casing strings. The body includes a passageway (25) which is in communication with the annulus near a lower end of the body and extends upwardly within the wall of the body towards the upper end of the body. A valve (27) is accommodated in the upper part of the body and provides controlled communication between the passageway (25) and a port (43) which can be coupled to the isolation sleeve. The valve is controllable from a production tree and in particular is moveable between an open position and a closed position in response to fluid pressure applied to the valve from a production tree by way of the isolation sleeve.
