    • A debris barrier (30) for a retrievable mechanical set packer is held retracted for run in. It is held spaced apart from upper slips (18) and uses a spring bias (16) that acts on the slips to keep them energized to also energize the barrier to the extended position to keep debris out of the upper slips (18) when the packer is set. The debris barrier (30) is preferably a sleeve that is axially compressed by the setting procedure to increase in diameter and span the gap between the packer mandrel (10) and the set upper slips (18). Retrieving the packer is enabled by a retraction of the debris barrier (30) as the upper slips (18) are undermined with rotation and pickup force on the packer mandrel (10). The lack of a debris barrier (30) could prevent retrieval of the packer in well bores where debris is present and has a tendency to settle around and more critically under the upper slips (18).
    • 用于可回收的机械定型封隔器的碎片挡板(30)被缩回以用于运行。其与上滑块(18)保持间隔开,并且使用作用在滑动件上的弹簧偏压(16)以保持其通电,同时激励 当封隔器被固定时,将阻挡物保持在上部滑动件(18)之外的位置以将碎屑保持在上方。 碎片挡板(30)优选是通过设定步骤轴向压缩的套筒,以增加直径并跨越封隔器心轴(10)和设定的上滑动件(18)之间的间隙。 通过在封隔器心轴(10)上的旋转和拾取力破坏上部滑块(18)时,通过使碎片屏障(30)回缩来实现取回封隔器。 缺少碎片屏障(30)可以防止在存在碎屑的井眼中的包装机的回收,并且具有在上部滑块(18)下方并且更严重地沉降的倾向。

    • An annular seal device includes a mandrel (12), at least one cone (14, 16) axially moveable on the mandrel, at least one sealing element (20, 22) having a frustoconical outer surface and a frustoconical inner surface, at least one contact feature (30, 32) at the at least one cone and operably engageable with the at least one sealing element, and at least one of a blocking element (40, 42) and a resilient member (18) at the mandrel, the at least one of a blocking element and a resilient member supporting a blocking surface in opposition to the at least one contact feature. The resilient member itself includes a tubular body having spring rings (54, 56) at axial ends thereof, and a plurality of beams (52) extending spirally from one axial end to the other axial end.
    • 环形密封装置包括心轴(12),至少一个可在心轴上可移动的锥体(14,16),至少一个具有截头圆锥形外表面和截头圆锥形内表面的密封元件(20,22),至少一个 在所述至少一个锥体处的所述接触特征(30,32),并且可操作地与所述至少一个密封元件接合,以及所述心轴处的阻挡元件(40,42)和弹性构件(18)中的至少一个, 阻挡元件和弹性构件中的至少一个支撑与所述至少一个接触特征相对的阻挡表面。 弹性构件本身包括在其轴向端部具有弹簧环(54,56)的管状体和从一个轴向端螺旋地延伸到另一个轴向端部的多个梁(52)。

    • An organization system for a series of objects to be sequentially run downhole is disclosed. The preferred objects are spheres of progressively larger diameter put into a wellbore to land at discrete locations for operation of ports in a given sequence so that a specific producing zone or zones can be completed in increments that preferably go in an uphole direction as progressively larger spheres are inserted. In the preferred embodiment the process is fracturing where a series of ported subs are operated to selectively open for the fracture procedure at a specific location and then close or become isolated when another sphere is dropped. Optionally the balls can be recovered at the surface when production starts. The organizer prevents size confusion and gives a ready feedback as to the progress of a given job. Trays can be stacked and carried in a carrying case.
    • 公开了一系列要在井下连续运行的物体的组织系统。 优选的对象是逐渐变大的直径的球体,其进入井筒以在离散位置着陆以在给定的顺序中操作端口,使得特定生产区域或区域可以以逐渐更大的球体优选地沿着井上方向完成 被插入。 在优选实施例中,该过程是压裂,其中一系列移动的子系统被操作以在特定位置处选择性地打开断裂过程,然后在另一球体掉落时闭合或变得隔离。 可选地,当生产开始时,球可在表面恢复。 组织者可防止大小混乱,并提供有关给定作业进度的即时反馈。 托盘可以堆放并携带在手提箱中。
