摘要： A milling bottom hole assembly (BHA) for use in cutting a full gauge window in a wellbore casing wall, the resultant length of the window being greater than or equal to the whipstock ramp length. A milling BHA is described which includes two shaft portions, a window mill and two bearing mills. The design, which involves strategically placed bearing mills, allows the milling BHA to stay on the whipstock ramp for the entire casing window milling operation and, thereafter, to optimally rapidly build angle and move laterally away from the whipstock and casing, creating a significantly long window which allows for easy passage of directional drilling BHAs through the milled window.
摘要翻译：用于在井眼套管壁中切割全量规窗口的铣削底孔组件（BHA），窗口的合成长度大于或等于造斜斜坡长度。描述了一种铣削BHA，其包括两个轴部分，一个窗口磨机和两个轴承磨机。该设计涉及到策略性地放置的轴承磨机，允许铣削BHA停留在造斜斜坡上用于整个套管窗铣削操作，此后，最佳地快速构建角度并且横向移离造斜器和套管，从而产生显着长的窗口，允许定向钻井BHA通过铣削窗口。

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 mill body is machined integrally with blades that have pockets to receive PDC inserts. The insert pockets can have an orientation feature to ensure that inserts that require specific rotational orientation are put into the pockets at the right orientation for efficient milling. The orientation of some of the pockets closest to the bottom and center of the bit have their axis reoriented to a near parallel orientation to the bit center axis to allow the bit body and blade fabrication equipment access to drill the insert pocket.
摘要翻译：磨机本体与刀片一体加工，刀片有容纳PDC插件的口袋。插入口袋可以具有取向特征以确保需要特定旋转取向的插入物以正确的方向放入口袋中以进行有效铣削。最靠近钻头底部和中心的一些凹座的取向使其轴线重新取向为与钻头中心轴线接近平行的方向，以允许钻头体和刀片制造设备进入钻头。

摘要： Earth-boring tools comprise a face and a plurality of cutting elements disposed on at least a portion of the face. An impact material is positioned on at least one portion of the body and has a relative exposure equal to or greater than at least some of the cutting elements of the plurality of cutting elements. The impact material comprises a material having a lower abrasion resistance than the body. Methods of making and methods of using such earth-boring tools are also disclosed.
摘要翻译：钻地工具包括面部和布置在面部的至少一部分上的多个切割元件。冲击材料定位在本体的至少一部分上并且具有等于或大于多个切割元件中的至少一些切割元件的相对暴露量。冲击材料包括具有比主体更低的耐磨性的材料。还公开了制造方法和使用这种钻地工具的方法。
