Abstract: A one trip method of cleaning a portion of the borehole and then setting a tool such as a packer or a bridge plug locates the cleanup tools above the plug with a ported sub to allow circulation of loosened debris. The debris is directed uphole from above the plug and does not have to pass around the sealing element of the plug or through bypass ports in the plug body. The plug is then positioned in the cleaned portion and set. The cleaning tools are released from the set plug and brought to the surface. These tools could be used to clean the portion of the borehole where the tool is set or clean the entire section above the tool on the trip out of the borehole. Cleaning tools can be filter, scrapers both fixed and movable, magnets, brushes and associated tools that centralize the assembly for more effective operation.

Abstract translation: 清洁钻孔的一部分然后设置诸如封隔器或桥塞的工具的一次方法将清洁工具定位在塞子上方，其具有移动的子部分，以允许松动的碎屑循环。 碎屑从插头上方向上引导孔，并且不必通过插头的密封元件或通过插塞体中的旁路端口。 然后将塞子定位在清洁部分中并设置。 清洁工具从设置的塞子中释放并带到表面。 这些工具可用于清洁工具所在井眼的部分，或者清除工具上方的工具上方的整个部分，使其脱离钻孔。 清洁工具可以是过滤器，固定和可移动的刮刀，磁体，电刷和相关联的工具，可集中组件以实现更有效的操作。

Abstract: Expandable brushes for cleaning a surrounding tubular member. Brushes include a housing to be disposed within the surrounding tubular member and a brush shoe that retains at least one brush bristle, the brush shoe being radially moveable with respect to the housing between a radially retracted position and a radially expanded position.
