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 folly 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： In one embodiment telescoping members (24,26) are extended to bridge an annular gap either before or after it is cemented. Some of the telescoping members have screens and others have flow passages that can be selectively opened with associated valves to frac an interval in any order desired. The valves are then closed after the frac job and the other telescoping members are made to allow screened flow from the fractured formation. In another embodiment an interval to be gravel packed and fractured has a series of screens (60,62,64,66) and selectively opened valves (72,74) on a bottom hole assembly (58) such as a liner. One or more external packers (68,76,78) are provided. The entire interval is gravel packed at one time followed by packer actuation and then selective opening of ports to conduct a fracture operation in any of the zones defined by the set packers and in any desired order.

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，夹头设置在与壳体相对的端部连接的柔性指状物上。周围的着陆套筒使组件停止，使得夹头与作为周围管柱的一部分的着陆轴环中的凹部对齐。一旦设置着陆套筒传递压缩载荷，使得压缩应力基本上绕过支撑夹头的指状结构。所述指状物最初朝向纵向轴线逐渐变细，以便当被内部支撑时，所述指状物呈现与壳体轴线对准的取向，以允许更大的拉伸负载并且在移除夹套支撑件后将要移除壳体时提供回缩力。

摘要： A flapper type downhole valve is opened by flow against the flapper. The flapper and the housing contain magnets that hold the flapper open after it has been opened by flow to keep the flapper from chattering from the flow going past it. The strength of the force is not sufficient to hold the flapper open against a torsion spring on a pivot pin, when there is no flow through the valve. The valve can still be held in the locked open position with no flow fihrough the housing by pressurizing the surrounding annulus to position another magnet to increase the holding force to a level greater than the force of the torsion spring. The additional magnet is spring biased so that upon removal of annulus pressure it shifts to allow the flapper to close. Alternative designs with and without a flow tube are possible. Fixed or movable restrictions can be associated with the flow tube to create a force to shift it to open a flapper with flow into the well.
摘要翻译：挡板型井下阀通过挡板上的流动而打开。挡板和外壳包含磁铁，在挡板被流动打开后，挡板可以保持打开状态，从而保持挡板不会因流过它的气流而颤动。当没有流量通过阀门时，力的强度不足以将挡板保持在枢销上的扭簧上。阀仍然可以保持在锁定打开位置，没有流量通过壳体，通过对周围环进行加压来定位另一个磁体以将保持力增加到大于扭转弹簧的力的水平。额外的磁铁是弹簧偏压的，因此在取消环空压力时，它会移动以允许挡板关闭。有和没有流量管的替代设计都是可能的。固定的或可移动的限制可以与流量管相关联以产生力以将其移动以打开带有流入井中的挡板。

摘要： Methods and apparatus for forming multilateral wells and sealing the junction between the main well bore and a lateral well. In a first embodiment of the invention, a main well bore liner includes windows or openings formed in the liner. A drillable insert is positioned near the window for support when the lateral well is drilled. The window is also filled with a drillable material. A second embodiment of the invention uses inflatable casing packers which are inflated with cement to form junction having pressure integrity from the inside and the outside with a full opening lateral and a main bore restricted only by the inner diameter of the inflatable casing packers. A third embodiment of the invention uses a layered sealing sleeve at the opening of the lateral well. A tie back liner top mandrel is wedged through an opening in the layered sealing sleeve. The mandrel includes a flange, at the top and the interference fit between the flange and the opening in the sealing sleeve forms a hydraulic seal between the main well bore and the lateral well.
