    摘要： The present invention provides a mudline connector (10) including a compression adaptor (40) which can be elastically deformed onto an internal tubular member.In the preferred embodiment the compression adaptor (40) deflects inwardly to grip an upper and a lower sealing mandrel (50, 56) in order to provide axial and bending load support and create a seal in order to isolate bore (160) pressure from an outer annulus (170) and vice-versa. The clamping arrangement (10) thereby provides a sealed connection between two well casing sections which extend in opposite axial directions. The well casings are gripped and held in an end to end configuration. The connector (10) does this by means of a radial load applied internally by a compression ring (60).The connector (10) is activated by introducing pressure into a piston port activation thus stroking an activation piston(s) (80) which in turn provides an axial thrust to stroke the internally tapered compression ring (60) along the externally tapered compression collar (70) effectively creating an interference fit therebetween. This deflects the inner surface of the compression collar (70) inwardly which thereby deflects the compression adaptor (40) inwardly in order to grip the outer surfaces of the upper and lower sealing mandrels (50, 56).

    摘要翻译： 本发明提供了一种包括压缩适配器（40）的泥线连接器（10），压缩适配器（40）可以弹性变形到内部管状构件上。在优选实施例中，压缩适配器（40）向内偏转以夹紧上部和下部密封心轴 以便提供轴向和弯曲载荷支撑并形成密封，以便从外部环形空间（170）隔离孔（160）压力，反之亦然。 夹紧装置（10）由此在沿相反轴向方向延伸的两个井套管部分之间提供密封连接。 井套管被抓住并以端对端的形式保持。 连接器10通过由压缩环60在内部施加的径向载荷来实现。连接器10通过将压力引入到活塞端口激活中而被激活，从而冲击一个或多个激活活塞80， 进而提供轴向推力以沿着外部锥形压缩轴环（70）冲击内部锥形压缩环（60），从而有效地在其间形成干涉配合。 这使压缩轴环70的内表面向内偏转，由此使压缩适配器40向内偏转以夹紧上密封心轴50和下密封心轴56的外表面。

    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： A clamp for clamping two concentric tubes, typically two concentric tubes in an oil or gas well. The clamp has two axially movable tapered components which can be pulled over one another in an axial direction to provide a contraction of internal diameter which grips the smaller diameter tube. In one embodiment, a spacer is fitted to allow the tapered components to be held apart until the tubes have been correctly positioned. The spacer is than removed, and the tapered components are drawn together to effect the clamping. A hydraulic ram can be provided to separate the tapered components should readjustment be required. In another embodiment, the larger diameter tube is made with a relatively thin wall, so that it can be distored inwards to grip the smaller tube.
