摘要： A combination tool for attaching to a stuck wireline tool, then cutting the wireline just above the stuck tool with a hydraulically driven cutter, allowing the wireline to be pulled out of the hole before fishing out the stuck tool. A side door can be provided on the work string, to allow rerouting of the wireline outside the work string, after which the stuck tool can be unstuck and repositioned within the well bore for completion of the downhole operation of the tool, prior to cutting the wireline free from the downhole tool.

摘要： A method and apparatus for severing the mandrel of an anchor device such as a packer to release the packer and remove it from a well. A cutter locator profile above the packer assembly and a cutter locator element on the cutting tool are located so as to precisely position the cutting element at a desired location on the packer mandrel. Once the mandrel is severed, the packer assembly can elongate to release the expansion mechanism. Then, the packer assembly can be pulled upwardly to release the packer, and to remove it from the well. A cutting tool can be lowered through production tubing to sever the mandrel, followed by pulling the packer with the production tubing. Alternatively, a cutting tool can be lowered on a workstring and latched to the upper end of the packer assembly, followed by severing the mandrel and pulling the packer with the workstring.
摘要翻译： 一种用于切断诸如封隔器的锚定装置的心轴的方法和装置，以释放封隔器并将其从井中移出。 位于封隔器组件上方的切割器定位器轮廓和切割工具上的切割器定位器元件被定位成将切割元件精确地定位在封隔器心轴上的期望位置处。 一旦心轴被切断，封隔器组件可以伸长以释放膨胀机构。 然后，封隔器组件可以被向上拉以释放封隔器，并将其从井中移出。 可以通过生产管道将切削工具降低以切断心轴，然后用生产管道拉动封隔器。 或者，切割工具可以在工作绳上下降并且锁定到封隔器组件的上端，随后切断心轴并用工作绳拉动封隔器。

摘要： A gearbox comprises a plurality of gear pairs each having a specific gear ratio, and a plurality of selectors each mounted between two gear pairs for selecting one of the two gear pairs, wherein the gear ratio of the selected gear pair is cascaded through an output shaft to another two gear pairs having another selector, and so on. In this way, the effective or aggregate gear ratio of the gearbox is the product of the gear ratios of the selected gear pairs. Thus, the number of available output speeds excluding neutral is given by 2n, where n=(number of gear pairs)/2.

摘要： A debris removal device features structural support from an exterior housing that allows more space for debris collection. The debris enters the collection volume from the top to eliminate debris from having to go through a valve. The screen in the device is disposed internally to protect it during handling and running. A variety of external flow diverters are used to direct debris laden fluid into the tool and to keep debris out of an annular space around the tool that could interfere with its removal. The diverters can be actuated by relative movement in the tool or applied pressure to a piston which can inflate a sleeve or orient or misalign paths through brushes for selective bypassing of fluid exterior to the tool.

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.
