摘要： The invention relates to an apparatus (10) for installing a wellbore (12) on a seabed (14). The apparatus includes a suction member (16) including a housing (17) defining a chamber (18). The housing (17) has an open end (20). The open end (20) defines a leading edge (22) for engagement with the seabed (14).The apparatus (10) includes a wellhead located (24) at an end opposite the open end (20) for engagement with a conduit (28). The conduit (28) is coupled to the housing (17). The conduit (28) extends from the wellhead means (24) through the chamber (18). When the wellbore (12) is installed on the seabed, the apparatus (10) provides a barrier or well barrier, which is capable of isolating and/or maintaining a wellbore pressure. The apparatus (10) allows for the installation of a wellhead (24) and/or a conduit (28) without the need of prior drilling and/or jetting operations at a wellbore site.

摘要： The invention relates to a well bore control apparatus, system and method for sealing a well bore. The invention relates to a well bore control apparatus (20) comprising a housing (27) having a guide element (36) defining a path, the housing defining a throughbore (23) for receiving a tubular, a first tapered gate (64a) and a tapered second gate (64b) located within the housing, the first and second gates being adapted to engage with the guide element. In use the first and second gates are moveable along the path defined by the guide element in a direction substantially transverse to the throughbore between an open position of the throughbore and a closed position of the throughbore. The well bore control apparatus comprises a first seal seat (42) for forming a first seal with the first gate in the closed position to seal the throughbore. The well bore control apparatus may include a second seal seat (44). The second seal seat may be adapted for forming a second seal with the second gate in the closed position to seal the throughbore.

摘要： An annular packer (10) for use with an annular blow out preventer (20) formed of a plurality of blades or elements (21,30,72) where each of the blades (21,30,72) is curved and arranged in the annular bore such that the curve of the blade is not parallel with the longitudinal axis of the assembly. This creates an “iris” type of geometry which, as the iris closes, the annular bore (24) transforms from a parallel cylindrical shape to a smaller bore with a shape having at least one waist or pinch point (32,34,73,75) of smaller cross-section.

摘要翻译：一种环形封隔器（10），与由多个叶片或元件（21,30,72）形成的环形防喷器（20）一起使用，其中每个叶片（21,30,72）被弯曲并布置在环形孔，使得叶片的曲线不平行于组件的纵向轴线。这产生了一种“虹膜”型几何结构，当虹膜关闭时，环形孔（24）从平行圆柱形变成具有至少一个腰部或收缩点的形状的较小孔（32,34,73， 75）的横截面较小。
