摘要： A tool and associated method allows a liner top to be dressed. Then while maintaining a lateral port closed the tool can be used to circulate while being rotated and reciprocated. The tool features discrete j-slot mechanisms. The upper j-slot allows the lateral port to initially open while the lower j-slot keeps the lateral port open despite movement of the tool in opposed directions in the hole due to a barrier to the pin in the lower j-slot. When enough weight is set or the barrier is otherwise removed, the lateral port can be closed and the test packer set by set down weight with the lateral port closed. After the packer is unset the lateral ports can be reopened and circulation and swiveling on a bearing can occur even if the packer is temporarily actuated from the setting down motion that reopened the lateral ports.

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 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 and movable 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和可移动部件。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，该工具在相反方向上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。
