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： A wellbore cleaning device having a unitary tool mandrel surrounded by a retaining sleeve that is rotatable with respect to the mandrel. A locking ring is used to secure the retaining sleeve to the mandrel. Cleaning blades are retained within recesses in the retaining sleeve and are biased radially outwardly from the recesses by springs.

摘要： A debris catcher uses induced circulation from a venturi to urge debris laden flow into the lower end of a housing. An inlet tube maintains velocity so as to keep the debris moving with the fluid stream as it goes up the inlet tube. A screen fits over the open end of the inlet tube and runs down around the inlet tube toward the entrance of the debris laden fluid into the lower end of the housing. There is a clearance around the cylindrical portion of the screen so some flow can exit that way. There is also an open exit through the top of the screen that can be reached after the fluid stream makes two hairpin turns. Many modules can be stacked. Each module has a large screen area for flow to exit and progressive modules can have smaller screen openings in an uphole flow direction.
摘要翻译：碎片捕捉器使用来自文丘里管的诱导循环来促使残渣流入壳体的下端。入口管保持速度以便当碎屑沿入口管上升时保持碎屑与流体流一起移动。一个筛子安装在入口管的开口端上，并且围绕入口管朝着含有碎片的流体入口进入壳体的下端。屏幕的圆柱形部分周围有间隙，所以有些流动可以以这种方式退出。在流体流形成两个发夹转弯之后，还可以通过屏幕的顶部打开一个出口。许多模块可以堆叠。每个模块都有一个大的屏幕区域供流出，而逐行模块可以在井上流动方向上具有较小的屏幕开口。

摘要： A debris catching device for downhole milling features modular debris receptacles that are held in the housing in a manner that facilitates stacking and a generally undulating flow path to facilitate dropping of the debris into the receptacles as the remaining fluid travels up the tool for ultimate screening before the fluid exits the tool to flow up to the surface or in a reverse circulation pattern back to the mill below the debris catcher. The modules can also be aligned with flapper valves at the top of each module to prevent debris in the tool from falling to the mill if circulation is turned off. The mill is configured to have an off-center return path preferably as large as the passage through the mill body to aid circulation and cutting performance.
摘要翻译：用于井下铣削的碎屑捕获装置的特征在于模块化碎屑容器，其以便于堆叠的方式保持在壳体中并且通常为波状的流动路径，以便随着剩余流体沿着工具向上行进以用于最终筛选，流体离开工具流向表面或以反向循环模式返回碎屑捕集器下方的磨机。这些模块还可以与每个模块顶部的挡板阀对齐，以防止在循环关闭时工具中的碎屑掉落到磨机中。碾磨机配置为具有偏离中心的返回路径，优选与穿过磨机主体的路径一样大，以有助于循环和切割性能。

摘要： A method of abandoning a borehole includes, running a tool into the borehole, cutting a casing with a first portion of the tool, reaming the borehole in an area where the casing has been cut with a second portion of the tool, disconnecting a drillstring from the tool, and cementing the borehole through the drillstring.

GB2514691A Spiral whipstock for low-side casing exits 未知

摘要： A whipstock features a spiral ramp so that, in a horizontal run, access to a milled window with other tools is not impeded because such tools can traverse onto the ramp and still be directed to the window. Angular rotation of the ramp can be at 180Â° or more and the pitch is selected to avoid getting the equipment being advanced into a bind. Optionally, a guide track can be configured into the whipstock ramp to help the mill follow the spiral path until the proper orientation is obtained and the track ends to allow separation of the mill from the track. A slot can be provided near the ramp upper end to aid in retrieval operations.
