摘要： Apparatus for the insertion of a pack-off (34) into a recess (51) in a bore of a wellhead body comprises an activating sleeve (36) which has a portion (58) disposed for engagement with the pack-off (34) for the movement of the pack-off into the recess and body portions shaped for location on a datum member (52) within the bore. The activating sleeve (36) includes a plurality of apertures (65) circumferentially spaced about the activating sleeve. A running tool (50) which is adapted to move said activating sleeve into engagement with the packoff carries spring-loaded dogs (72) each disposed in one of the apertures (65). Each of a plurality of releasing pins (71) is positioned such that it enters a respective one of the apertures (65) when the activating sleeve (36) has caused the packoff (34) to be located in said recess (52). The entry of the pins (71) into the apertures causes depression of the dogs out of the apertures and allows the consequent release of the activating sleeve (36) from the running tool (50).

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.
摘要翻译：海底井口包括大致圆柱形的主体，其包括用于在下部延伸部和外部导体之间形成水泥柱的环形空间（11）的下部延伸部（9）。延伸部具有形成套筒的多个配合环（13b），其有助于在存在水泥柱的情况下延伸部的挠曲。每个环可以包括用于邻近延伸部外侧配置的内凸缘和用于装配在相邻环的内凸缘上的外凸缘。外凸缘可以具有径向通孔。
