摘要： Magnetic retrieval tools for use in a wellbore or other tubular member to remove metallic debris. A magnetic retrieval tool includes a tool body having a central shaft with a plurality of ribs that project radially outwardly therefrom. The ribs present lateral sides that have recesses formed therein. Magnet bars are retained within the recesses by wedge members and retaining rings. The magnet bars include a hollow protective housing that encloses a plurality of magnets. Retaining plugs are used to secure the magnets within the housing.

摘要： A magnetic retrieval tool used for collecting metallic debris and material from within a wellbore or other surrounding downhole tubular. The tool includes a tool mandrel with one or more pockets formed in its outer radial surface. A removable insert resides within each pocket. Each of the inserts retains a plurality of individual magnets in a fixed array or matrix surrounding the mandrel.
摘要翻译：一种用于从井眼或其他周围井下管道内收集金属碎屑和材料的磁回收工具。该工具包括具有在其外径向表面中形成的一个或多个凹穴的工具心轴。一个可拆卸的插入物位于每个口袋内。每个插入件将多个单独的磁体保持在围绕心轴的固定阵列或矩阵中。

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。
