摘要： A collet assembly has a housing and the collets disposed on flexible fingers connected to the housing at their opposed ends. A surrounding landing sleeve stops the assembly so that collets are aligned with a recess in a landing collar that is part of a surrounding tubing string. Once set the landing sleeve transmits compressive loads so that compressive stress essentially bypasses the finger structure supporting the collets. The fingers are initially tapered toward a longitudinal axis so that when internally supported they assume an aligned orientation to the housing axis to allow greater tensile loading and to provide a retraction force when the housing is to be removed after the collet support is removed.
摘要翻译：夹头组件具有壳体，并且夹头设置在柔性指状物上，在其相对端部处连接到壳体。周围的着陆套筒停止组装，使得夹头与作为周围油管柱的一部分的着陆轴环中的凹部对准。一旦设置，着陆套筒就会传递压缩载荷，使得压缩应力基本上绕过支撑夹头的手指结构。手指最初朝着纵向轴线渐缩，使得当内部支撑时，它们采取与壳体轴线对齐的取向，以允许更大的拉伸载荷，并且在夹套支撑件被移除之后要移除壳体时提供回缩力。

摘要： A completion tubular is placed in position adjacent the zone or zones to be fractured and produced. It features preferably sliding sleeve valves that can assume at least two configurations: wide open and open with a screen material juxtaposed in the flow passage. In a preferred embodiment the valve assembly has three positions, adding a fully closed position to the other two mentioned. After run in, the valves can be put in the wide open position in any order desired to fracture. After fracturing, the valves can be closed or selectively be put in filtration position for production from the fractured zones in any desired order. Various ways are described to actuate the valves. The tubular can have telescoping pistons through which the fracturing can take place if the application calls for a cemented tubular. Alternatively, the tubular can be in open hole and simply have openings for passage of fracture fluid and external isolators to allow fracturing in any desired order.

摘要： A packer assembly which incorporates a swellable elastomeric packer element and one or more swellable thermoplastic components. The swellable thermoplastic components are support rings that are located at each axial end of the elastomeric element and provide positive mechanical backups for the elastomeric element to limit extrusion of the packer element.

摘要： Preformed ribs are held closely to the swelling element and then are allowed to assume an expanded position to capture the ends of the swelling element. Many variations are possible one of which is retaining the ribs in a run in position with a band that releases by interaction with well fluid. In another embodiment the ribs are of a shape memory material and go to the enlarged state after a time and exposure to well fluids. The swelling action of the element could urge the ribs to the expanded position. Alternatively, a retractable sleeve can be actuated after a delay using a piston and a sealed compartment where a material must dissolve or otherwise go away before the piston can stroke to remove a retainer from ribs that can then move out.
摘要翻译：预形成的肋条紧紧地固定在膨胀元件上，然后被允许呈现膨胀位置以捕获膨胀元件的端部。许多变型是可能的，其中之一是通过与井流体的相互作用而释放的条带将肋保持在位置。在另一个实施例中，肋是形状记忆材料，并且经过一段时间并暴露于良好的流体之后进入放大状态。元件的膨胀作用可以促使肋条处于膨胀位置。或者，可以在使用活塞和密封隔室的延迟之后致动可伸缩套筒，其中材料必须溶解或者在活塞行程之前去除，以将保持器从可以移出的肋部移除。

摘要： A system allows for sequential treatment of sections of a zone. Access to each portion can be with a sliding sleeve that has a specific internal profile. Pump down plugs can be used that have a specific profile that will make a plug latch to a specific sleeve. Pressure on the plug when latched allows a sequential opening of sleeves while zones already affected that are below are isolated. The pump down plugs have a passage that is initially obstructed by a material that eventually disappears under anticipated well conditions. As a result, when all portions of a zone are handled a flow path is reestablished through the various latched plugs. The plugs can also be blown clear of a sliding sleeve after operating it and can feature a key that subsequently prevents rotation of the plug on its axis in the event is later needs milling out.

摘要： A self-lubricating swage expands tubulars and includes a primary swaging tool supported on a mandrel that has a lubricious capacity or a primary swaging tool supported on a mandrel and a nose swage member supported on an end of the mandrel. In the latter the nose swage member is fabricated of, is coated with or otherwise includes and applies a lubricious material that smears onto a surface coming into contact with the nose swage member. The smearing of the lubricious material facilitates the sliding of the swaging member as it contacts the inner walls of the tubular.

摘要： A method and apparatus to provide a large bore hook hanger system incorporating sand exclusion at a junction in a multilateral wellbore includes the running of a lateral liner having an expandable sleeve positioned thereon to bridge a milled window from the lateral borehole to the primary borehole, expandable sleeve including a pre-machined window and a hook to hang the liner from the primary borehole. The hook further acts to center the pre-machined window in the expandable sleeve to provide access to the primary wellbore. The expandable sleeve is preferably covered on its outer surface with an elastomeric material and is outwardly concentric to an expandable packer for run-in. Once the expandable sleeve is positioned at the appropriate location in the junction, the expandable packer is inflated thus permanently deforming the expandable sleeve into contact with the open hole of the lateral borehole thereby preventing sand or gravel ingress to the primary borehole.

摘要： Several downhole flow control devices are disclosed which are meterable and are also capable of shutting of a particular zone in a well. The several embodiments include a multiple valve body, a toroidal inflatable valve, and a series of related choke systems. The downhole flow control choke mechanisms each include a downhole electronics package to provide programming or decision making capacity as well as motor actuation systems. Each choke mechanism also includes a system whereby the device can be converted to manual operation and actuated by a conventional shifting tool.
