摘要： A wellbore cleanup tool collects debris when moved in one direction downhole. A flow diverter is extended for such flow diversion when debris is collected. When running the tool in the opposite direction in the wellbore, the flow diverter is in whole or in part articulated to retract so as to reduce resistance to fluid that passes around the outside of the tool. A segmented diverter can have fixed (20) and movable (22) components that are guided. The movable components can become longitudinally offset from the fixed components for movement in the direction where maximum flow bypass around the outside of the tool is desired. In an alternative embodiment, the diverter segments can all be movable on an inclined track to retract against a bias force for fluid bias with movement of the tool in the opposite direction allowing the bias to push the segments on the inclined track for diversion of debris laden fluid into a capture volume in the tool.
摘要翻译：井下清理工具在井下一个方向移动时收集碎屑。当收集碎片时，流量分流器被扩展用于这种流动分流。当在井眼中以相反方向运行工具时，流动分流器整体地或部分地铰接以缩回，以便降低对穿过工具外部的流体的抵抗力。分段分流器可以具有被引导的固定（20）和可动（22）部件。可移动部件可以从固定部件纵向地偏移，以便在期望围绕工具外部的最大流动旁路的方向上移动。在替代实施例中，分流器段可以在倾斜的轨道上都可移动，以抵抗用于流体偏压的偏压力而退回，同时工具沿相反方向的运动允许偏压推动倾斜轨道上的段，流体进入工具中的捕获体积。

摘要： A casing spear may comprise a mandrel, and a slip assembly comprising at least one slip. The at least one slip may comprise a generally wedge-shaped surface positioned and configured to cause the at least one slip to move radially outwards relative to the mandrel in response to a rotation of the mandrel and a torque acting on the slip assembly, the torque opposing the rotation of the mandrel. Additionally, a method of operating a casing spear may comprise inserting a casing spear into a casing, rotating a mandrel of the casing spear, applying a torque to a slip assembly of the casing spear with the casing, opposing the rotation of the mandrel, and applying a force in a radial direction to at least one slip of a slip assembly of the casing spear in response to the torque.

摘要： A ball catcher is designed to stop balls that are the same size or different sizes at an inlet on a seat that is connected to a movable biased sleeve. Once the ball or other shaped object lands at the seat the flow around it increases differential pressure on the seat and sleeve and displaces them against the bias. The ball goes into a surrounding annular space and cannot exit. A preferably spiral sleeve guide the movement of the balls in the annular space so that efficient use of the annular space is made to maximize the number of balls that can be captured per unit length of the annular space. As soon as the ball enters the annular space the sleeve shifts back to the original position to stop the next ball at the inlet. Once in the annular space, the balls cannot escape if there is a flow reversal. The central passage remains open to pass other tools and flow.
摘要翻译：球捕获器被设计成在连接到可移动偏置套筒的座椅上的入口处停止具有相同尺寸或不同尺寸的球。一旦球或其它成形物体落在座椅上，则围绕它的流动增加了座椅和套筒上的压差，并使它们抵抗着偏压。球进入周围的环形空间，不能退出。优选螺旋套管引导球在环形空间中的移动，从而使环形空间的有效使用最大化可以使每单位长度的环形空间捕获的球数。一旦球进入环形空间，套筒就会移回原来的位置，以阻止入口处的下一个球。一旦在环形空间中，如果存在流动反转，则球不能逃逸。中央通道仍然可以通过其他工具和流动。
