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 180° 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.

摘要： A method and associated equipment are disclosed which allow drilling at least a portion of a well and subsequently cementing casing in a single trip. The method is particularly suited for deep-water offshore operations where the drill string can be run through a section of casing leaving a bit and an under-reamer extending out below. The casing is equipped with ports through which cement can be pumped as well as an external casing packer to prevent the uncured cement in the annulus from U-tubing. Several casing sections can be run in during drilling and cemented succession using the one trip method.

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 debris removal tool uses a screen to separate the debris coming into the tool from the moving fluid. The fluid that gets through the screen then operates a flow sensing device that is preferably a turbine whose speed of rotation or other characteristics of its movement generates a signal that is picked up by the measurement while drilling tool and conveyed to the surface. The surface personnel first respond by turning off surface pumps to allow debris to fall by gravity off the clogged screen. If that fails, the tool is pulled through the well fluid inducing a reverse flow through the screen to get the debris blocking it to go back into the well through the debris removal tool inlet.

摘要： Devices and methods for translating tubulars within a wellbore and, as a result, effectively freeing a stuck tubular string within a wellbore. One or more vibrator devices are incorporated into a tubular string, such as a drill string. Each of the vibratory devices may be turned on or off independently, as needed, to help effectively free the tubular string from a stuck condition.

摘要： A downhole vibration tool consisting of a body assembly installed in a work string, and a drop-in dart valve assembly. An open inner bore through the body assembly allows the performance of operations through the body assembly. To activate the vibration tool, the dart valve assembly is dropped into the work string and pumped downhole into engagement with the body assembly. Once the dart valve assembly is in place in the body assembly, continued pumping of fluid will cause the tool to begin to vibrate longitudinally. When the jarring operation is finished, the dart valve assembly can be released from the body assembly and retrieved, with a wireline or coiled tubing unit.
