    • A blow out preventer (10) includes a housing (40) defining a longitudinal throughbore (16) and a ram cavity (34) and at least one pair of opposed rams (12, 14) located in the ram cavity. Each ram includes a seal (18, 24) disposed on an upper surface (20, 26) and the rams are movable transversely across the bore. The blow out ereventer further includes at least one seal seat (30) having a seal surface (36) for engaging with the ram seals. There is a seal seat associated with each at least one pair of rams, the seal seat being moveably mounted in the ram cavity. In one embodiment the seal seat continuously engages the rams as the rams move from a cavity open position to a cavity closed position.
    • 防喷器(10)包括限定纵向通孔(16)和冲压腔(34)的壳体(40)和位于冲压腔内的至少一对相对的柱塞(12,14)。 每个压头包括设置在上表面(20,26)上的密封件(18,24),并且所述柱塞横向穿过所述孔移动。 吹出式减震器还包括至少一个具有密封面(36)的密封座(30),所述密封面用于与冲头密封件接合。 与每个至少一对柱塞相关联的密封座,密封座可移动地安装在冲压腔中。 在一个实施例中,当凸起从空腔打开位置移动到空腔关闭位置时,密封座连续接合凸起。

    • A winch assembly (10) comprises a winch drum (18) rotatable about a first axis and carrying a spoolable medium, such as wireline (14) for use in deploying and retrieving tooling into and from a well bore. A carriage sheave (30) mounted on a drive screw (34) is positioned adjacent the winch drum (18), wherein the drive screw (34) is rotatable about a second axis substantially parallel to the first axis. In use, the carriage sheave (30) engages the spoolable medium and is translated by the drive screw (34) in reverse directions to follow the fleeting motion of the spoolable medium as the medium is paid out and/or in from the winch drum (18). In a disclosed embodiment, the winch drum (18) is mounted vertically on a tubular body (22), through which tubular body (22) the spoolable medium extends into the well bore. In one embodiment the winch assembly (10) forms part of a subsea well intervention system.
    • 绞盘组件(10)包括可围绕第一轴线旋转并且承载可绕线的介质(例如用于将钻井和从井孔中取出工具)的缆线(14)的绞盘鼓(18)。 安装在驱动螺杆(34)上的滑轮(30)位于绞盘鼓(18)附近,其中驱动螺杆(34)可绕基本上平行于第一轴线的第二轴线旋转。 在使用中,托架滑轮(30)接合可卷绕介质并且由驱动螺杆(34)沿相反方向平移,以便随着介质从绞盘滚筒(...) 18)。 在公开的实施例中,绞盘鼓(18)垂直地安装在管状体(22)上,管状体(22)可卷绕介质延伸到井眼中。 在一个实施例中,绞车组件(10)形成海底井介入系统的一部分。
