摘要： A flow sensor is incorporated into a junk basket to sense a flow stoppage due to a plugged screen or plugged cuttings ports in a mill. The sensor triggers a signal to the surface to warn personnel that a problem exists before the equipment is damaged. The sensor signal to the surface can take a variety of forms including mud pulses, a detectable pressure buildup at the surface, electromagnetic energy, electrical signal on hard wire or radio signals in a wifi system to name a few options. Surface personnel can interrupt the signal to take corrective action that generally involves pulling out of the hole or reverse circulating to try to clear the screen or mill cuttings inlets. Other variables can be measured such as the volume or weight or rate of change of either and a signal can be sent to the surface corresponding to one of those variables to allow them to be detected at the surface in near real time.
摘要翻译：流量传感器被结合到垃圾篮中以感测由于在轧机中堵塞的筛网或堵塞的切屑端口引起的流动停止。传感器触发信号到表面，以警告人员在设备损坏之前存在问题。到表面的传感器信号可以采取各种形式，包括泥浆脉冲，表面上可检测的压力积聚，电磁能量，硬线上的电信号或WiFi系统中的无线电信号，以列举几个选项。表面人员可以中断信号采取纠正措施，通常包括从孔中拉出或反向循环，以尝试清除屏幕或铣削进样口。可以测量其他变量，例如任一个的体积或重量或变化率，并且可以将信号发送到与这些变量中的一个变量相对应的表面，以允许它们以近实时的方式在表面被检测。

摘要： A disconnect device comprises a tubular member having a window for receiving an engagement member, and a sleeve having connected and disconnected positions. The engagement member engages with a component of a downhole string to connect the disconnect device to the rest of the string such as through a helically-shaped thread disposed on the engagement member and on the component. The window can comprise at least one wall that is outwardly tapered so as to prevent the engagement member from passing through the window when the tubular member is disconnected from the component of the string. The engagement member is maintained within the window by the sleeve when in its connected position to maintain the connection between the tubular member and the component. When moved to its disconnected position, the engagement member disengages the component by moving inwardly into the bore of the tubular member.
摘要翻译：断开装置包括具有用于接收接合构件的窗口的管状构件和具有连接和断开位置的套管。接合构件与井下柱的组件接合，以将断开装置连接到串的其余部分，例如通过设置在接合构件上和组件上的螺旋形螺纹。窗口可以包括至少一个向外锥形的壁，以便当管状构件与柱的部件断开时防止接合构件穿过窗口。当处于其连接位置时，接合构件通过套筒保持在窗内，以保持管状构件和部件之间的连接。当移动到其断开位置时，接合构件通过向内移动到管状构件的孔中而脱离组件。

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： The debris collection device operates on an eductor principle with motive fluid delivered from the surface into an eductor housing inlet. The eductor outlet goes into a surrounding annular space and splits with some flow going to the mill below to direct cuttings into the passage in the housing. The cuttings remain in the housing and the flow continues through a screen in the housing passage before reaching the eductor inlet. An auxiliary inlet is normally closed and opened with a reduced flow entering through the mill. The opening of the auxiliary inlet drops the surface pressure delivered to the eductor to act as a surface signal that a plugged or low debris laden inlet flow exists.
摘要翻译：碎片收集装置以喷射器原理工作，其中从表面输送到喷射器壳体入口的动力流体。喷射器出口进入周围的环形空间，并分开一些流到下面的轧机，以将切屑引导到壳体中的通道中。切屑保留在壳体中，并且流体在到达喷射器入口之前通过壳体通道中的筛网继续。辅助入口通常关闭并打开，通过磨机进入的流量减少。辅助入口的开口降低了输送到喷射器的表面压力，作为存在堵塞或低碎片入口流的表面信号。

摘要： Multiple section mills are run in a single trip with an intervening mill preferably a watermelon mill to grind up any cuttings that get past the first mill in a direction toward the second mill below it. The blades of the second mill are held by the innermost tubular until the location of the initial cut is reached at which point the longer arms of the second mill can be extended and its body centralizes due to the flexibility of the connection between the mills.

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 method for locating placement of a guide stock in a multilateral well wherein the guide stock is properly aligned with the lateral borehole is disclosed. The method employs an impression packer with a scribed reference line to provide information at the surface regarding the lateral borehole's exact location and orientation with respect to the originally installed whipstock packer. This information is then employed to make up a guide stock and orientation sub to properly orient the diverter face of the guide stock with the lateral borehole. Tool embodiments for inflating the ipression packer to a preset relatively low internal pressure are also disclosed. In one embodiment, the inflation fluid is carried downhole in the tool and is released to the packer on set down pressure, the fluid being drawn back out of the packer upon pick up. In another embodiment, the impression packer is outfitted with an automatically closing valve. The valve can be mechanically electromechanically or electrically activated and may work in combination with a controller.

摘要： Apparatus and method for monitoring the wear of a downhole tool, and providing indication of the degree of wear to an operator at the well surface. A pressurized fluid path within the cutting element matrix can exhibit a pressure drop when wear of the matrix progresses into the fluid path, or rotating torque can exhibit a drop when wear of the matrix progresses to wear pads within the cutting element matrix. Other wear indicators can also be built into the cutting element matrix. Progression of wear down to the indicator can be directly measured at the well surface, or relayed to the surface via a downhole communication system.
