摘要： A wellhead securement arrangement releasably clamps casing strings such that they cannot move in an upwards or downwards longitudinal direction. Prior to being clamped, the securement arrangement secures the casing strings in a first position whereby cement returns are able to flow around the hangers towards the surface. Once cemented, the casing strings are released and moved upwardly, where the securement arrangement clamps the hangers into position, thus creating an axial load on the casing strings while also preventing movement in the upward and downward longitudinal directions.

摘要： The present invention provides monitoring means for monitoring the space and volume within a lower annulus. In particular, the monitoring means monitors the space and volume within the lower annulus 52 located between the inner surface of the 22 intermediate casing string 22 and the outer surface of the inner casing string 32. Furthermore, the monitoring means provides the capability to retrieve and/or introduce fluid(s) into the annular space 52. The monitoring means provides a port, specifically a passageway 100, which extends upwardly from the annular space 52 to an outlet located above the hanger 36 for the intermediate casing string 22. The passageway 100 is provided in a sleeve 102. The monitoring means includes a sensor located above the hanger 36 which means that the fluid in the annular space 52 can be monitored without the need for penetrating a casing in the wellhead.

摘要： The present invention provides a wellhead securement arrangement including a first inner casing string 32 which is held in axial loading and a second inner casing string 56 which is also held in axial loading. Both of the first and second inner casing strings 32, 56 are releasably clamped such that the casing strings 32, 56 cannot move in an upwards or a downwards longitudinal direction. Prior to being clamped in such a position, the wellhead securement arrangement provides first retaining means to retain the first and second casing strings in cementing position whereby “cement returns” are able to flow around the respective hangers 36, 58 and upward through a casing towards the surface. Once cemented, the upper hangers 36, 58 of the respective inner casing strings 32, 56 are moved upwardly where the hanger 36, 58 is then clamped in position to maintain the respective inner casing string 32, 56 under an axial load whilst being prevented from moving either upwardly or downwardly.

摘要： A sealing device is provided for making a seal against an annular surface. The device includes at least one flexible seal ring having a relaxed position in which the seal ring is out of contact with the surface and an active position in which the seal ring is in sealing contact with the surface, an operating member movable relative to the seal ring in a direction substantially parallel to the annular surface to produce a substantially radial movement of the ring into the active position, and a plurality of elongate, substantially parallel shape-memory material actuators arranged around the annular surface. A change of shape of the actuators produces the movement of the operating member which moves the seal ring into the active position.
