用于井口基座的系统和方法
摘要：
一种用于一个或多个海底井的井口基座，所述井口基座包括抽吸基座(1)，其设置有具有敞开底部(114)和能用顶盖(112)闭合的顶部的壳体(11)，以及一个或多个管(12、12a、12b)，其连接到壳体(11)并且从壳体(11)的顶部延伸并至少延伸跨越壳体(11)的垂直范围的大部分并至少在垂直方向上远离壳体(11)，每个管(12、12a、12b)的直的上部分(121)在壳体(11)的顶部以上向上突出并且形成上导体套管部分(131)，其布置成接收上井管部分(141)并且形成井中低压屏障的一部分，并且每个管(12、12a、12b)的直的上管部分(121)被布置成平行于壳体(11)的中心轴线。还描述了建立海底井口基座的方法。
摘要（英）：

A wellhead foundation for one or more subsea wells, the wellhead foundation comprising a suction foundation (1) provided with a housing (11) with an open bottom (114) and a top which is closable with a top cover (112), and one or more pipes (14, 14a, 14b) being attached to the housing (11) and extending from the top of the housing (11) and at least over a substantial part of the vertical extent of the housing (11) towards or beyond the open bottom (114) of the housing (11) inside or outside of the periphery of the housing (11), and a straight upper portion (141) of each pipe (14, 14a, 14b) projecting up above the top of the housing (11) and forming an upper well- pipe portion which forms part of a high-pressure barrier in the well, and the straight upper pipe portion (141) of each pipe (14, 14a, 14b) being arranged parallel to the centre axis of the housing (11). A method of establishing a subsea wellhead foundation is described as well.
