    • Using a specially designed push-on coupling structure the facing end portions of two tubular well completion structures, such as a length of coil tubing and a tubular coupling member, are fixedly and sealing connected to one another simply by pushing one of the end portions into the other end portions. The coupling structure includes an O-ring seal member carried by one of the end portions for creating a fluid tight seal between the telescoped end portions; a radial projection carried by one of the end portions and receivable in a side wall slot in the other end portion for preventing appreciable relative rotation between the telescoped end portions; and an axially split locking ring member coaxially threaded onto one of the end portions and having a gripping thread section disposed thereon and operative to engage the other end portion in a manner permitting the two end portions to be initially telescoped with one another but precluding their subsequent axial separation. This push-on coupling apparatus is representatively illustrated as being incorporated in a coil tubing splice member, on opposite ends of a tubular well completion device such as a landing nipple, and on a two piece push-together coupling structure used to operatively connect two tubular sand screen sections.

    • A two-way retrievable packer plug is installed in the production bore of a flow conductor by straight insertion, and is retrieved by a one trip straight pull operation. The plug assembly includes a core mandrel which is enclosed within a tubular latch mandrel on which an annular seal assembly is mounted for sealing engagement against the production bore of a flow conductor. A latch key is yieldably biased by a coil spring for interlocking engagement with a latch retainer lug carried on a landing receptacle attached to the flow conductor. The latch key is moveable from a radially extended position in which it is engageable against the latch retainer lug so that the latch key is blocked against axial displacement relative to the landing receptacle as the plug mandrel is inserted into or withdrawn out of the flow conductor. The latch key is moveable to a radially retracted position in which it is released from blocking engagement with the latch retainer lug to permit passage of the latch key relative to the lug as the core mandrel is fully inserted within or fully retracted from the flow conductor. The latch key is supported in the radially extended position by raised shoulder portions of the core mandrel. The core mandrel is intersected by an equalizing passage which is open during run-in and insertion. The equalizing passage is sealed automatically by a slideable isolation sleeve as the running tool is separated from the plug, and is opened automatically during retrieval of the plug.
    • 双向可回收封隔器插头通过直插式安装在流动导管的生产孔中,并通过一次拉直操作来取回。 插头组件包括芯心,其被封装在管状闩锁心轴内,安装有环形密封组件以密封与流动导体的生产孔密封接合。 闩锁钥匙可被螺旋弹簧屈服偏置,用于与附接到流动导体的着陆插座上承载的闩锁保持器凸耳互锁接合。 闩锁键可从径向延伸的位置移动,在该延伸位置中,闩锁键可与闩锁保持器突耳接合,使得当插头心轴插入或从流动导体中取出时,锁定键被阻止相对于着陆接收器的轴向位移。 闩锁键可移动到径向缩回位置,在该状态下,当芯轴心完全插入流动导体内或完全从流动导体缩回时,闩锁钥匙被释放以阻止与闩锁保持器突耳接合,以允许闩锁钥匙相对于突耳移动。 闩锁键通过芯心轴的凸起的肩部支撑在径向延伸的位置。 芯轴由平衡通道相交,在通入和插入过程中打开。 当运动工具与插头分离时,平衡通道由可滑动的隔离套筒自动密封,并在插头取出期间自动打开。

    • A retrievable packer includes a selectively releasable anti-rotation coupling lug for preventing premature setting of the packer. The lower wedge and packer mandrel are coupled together by the anti-rotation lug during running and setting operations. The anti-rotation lug is slidably received within an L-slot formed in the packer mandrel, and is selectively releasable to permit rotation of the service tool relative to the packer mandrel during retrieving operations. During run-in and retrieving operations, the anti-rotation lug is confined within a circumferentially extending portion of the L-slot, thereby limiting longitudinal travel of the packer mandrel relative to the lower wedge. The service tool can then set down on the packer for pushing the lower wedge out from under the anchor slip. The anti-rotation lug also provides a rotational lock between the slip carrier and the lower wedge, thereby preventing rotation of the slip carrier and anchor slips relative to the lower packer components during running and setting operations.
    • 可回收封隔器包括用于防止封隔器过早设置的可选择性释放的防旋转联接凸耳。 在运行和设置操作期间,下楔形物和封隔器心轴通过防旋转凸耳联接在一起。 防旋转凸耳可滑动地容纳在形成在封隔器心轴中的L形狭槽内,并且可选择性地释放以允许在检索操作期间相对于打包器心轴旋转维修工具。 在进入和取回操作期间,防旋转凸耳限制在L形槽的周向延伸部分内,从而限制封隔器心轴相对于下楔形件的纵向行进。 然后,服务工具可以在封隔器上放下,以将下部楔块从锚杆下方推出。 防转动凸耳还在滑动承载件和下部楔块之间提供旋转锁定,从而防止在运行和设置操作期间相对于下部封隔器部件的滑动滑架和锚定滑块的旋转。

    • An earth well completion apparatus and method wherein a work string equipped for jet washing downhole filtration devices, such as well screens and for back washing said downhole filtration devices and containing multiple ball catcher subs which utilize the same drop ball to prevent the inadvertent operation of hydraulically powered tools as well as to permanently valve closed a portion of said work string is concentrically disposed in a production string and run in said well simultaneously. Said ball catcher sub which prevents the inadvertent actuation of said hydraulically operated tools is contained within the main fluid bore of said work string and has an expellable inner collar with an outwardly biased catcher ring which, when expelled, shears hollow shearable means thereby actuating said tool. Expansion of said catcher ring frees said drop ball to fall into a catcher sub which has a retention groove milled into its inner circumference into which said drop ball extrudes thereby preventing its expulsion due to back pressure.
