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： 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：碎片收集装置按照喷射器原理操作，动力流体从表面输送到喷射器壳体入口。喷射器出口进入周围的环形空间并且以一些流向下面的研磨机的方式分流以将切屑引导到壳体中的通道中。切屑留在壳体中，并且在到达喷射器入口之前，流体继续通过壳体通道中的筛网。一个辅助入口通常是关闭的，并且通过磨机进入的流量减少而打开。辅助进气口的开启降低了输送到喷射器的表面压力，以充当表面信号，表明存在堵塞或低碎片负荷进气流。

摘要： A mill cutting structure is differently configured in three zones. Those zones are the center, the outer edge and in between. At the center has highly wear resistant material that has good temperature bond strength and high impact resistance. The outer periphery can have a material that is highly resistant to wear and impact. In between can be inserts such as used in the Metal Muncher® mills using sintered carbide shapes that resist tracking and create a chipping rather than a grinding action. The shapes should have high edge retention capability and shapes such as a double sided pyramid can be used. The wear patterns of prior designs are addressed to allow longer and faster milling of the fish.

摘要： Cutting elements for downhole cutting tools comprise a top surface having a cutting surface portion and a cutting profile asymmetrically disposed across the top surface. The cutting elements comprise first and second longitudinal side surfaces and first and second lateral side surfaces, each having a respective cross-section. The cross-section of one of the longitudinal side surfaces can have one beveled portion and the cross-sections of the other longitudinal side surface and the first and second lateral side surfaces can have two beveled portions. A cutting end of a downhole cutting tool comprises two cutting elements disposed facing each another with a portion of the cutting surface portion of a first cutting element being disposed opposite the cutting profile of the second cutting element and the cutting surface portion of the second cutting element being disposed opposite the cutting profile of the first cutting element.

摘要： A cutting assembly for external conduits on a tubing string or main tubular conduit features at least one breakaway in the string that can be severed with a tensile force. Preferably each external conduit is run through a cutter housing that is integral with a passage having threaded end connections. While in some scenarios it is preferred that the main tubular conduit is severed below the cutting assembly thus allowing the cutting apparatus to be retrieved with the upper portions of the cut main tubular conduit and external longitudinal member(s), in other circumstances it may be desired that the main tubular conduit is severed above the cutting assembly allowing the cutting apparatus to be left "downhole" with the lower portion of the cut main tubular conduit and the BHA. The cutter knife assembly chambers or channels can be in banks that are axially spaced using bypass channels to access lower banks. The cutter knife assembly and associated channels can be mirror images so that the external conduits can be cut regardless of where the tubing string is severed and one or more conduits can be cut with a single cutter assembly.

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： A mill is configured to have large debris passages disposed among a series of radially extending blades. The mill center is adapted to accept a retention nut that supports a tool that secures the downhole tool being milled out, such as a packer. Reverse flow takes cuttings into the large open area between the blades to pass up in an annular space around a support for the retention nut. The passage then opens up to a maximum dimension leaving only the tubular wall needed for structural strength to support the mill and conduct cuttings into a debris removal tool.

摘要： A tubular cutter that cuts with extendable and rotating blades has its depth of cut limited upon getting through the tubular to be cut. In a preferred embodiment, the tubular has a loosely mounted member exterior thereto to be engaged by the rotating cutters. When such engagement happens the effect is that the loosely mounted member serves as a cover to the cutters to prevent them from cutting other structures beyond the tubular to be cut. The loosely mounted member is grabbed by the rotating blades for tandem rotation this preventing further cutting action. The load on the mill drops noticeably so that surface personnel have a signal to stop hydraulic pressure to the drive mechanism to allow the blades to retract and the cutter to be removed.

摘要： An eductor sub is used as a portion of a downhole debris removal apparatus. It features an eductor outlet port that is selectively closed for run in to allow flow pumped through a tubing string to all go to the lower end of the debris removal tool to fluidize the debris and help prevent the tool from getting stuck on the way to the desired depth. When the desired depth is reached a ball lands on a seat that is connected to a sleeve that is displaced to move the sleeve away from the eductor outlet so that future flow coming down the casing string will create a reduced pressure within the tool to draw some of the exiting flow after the eductor exit in a downhole direction along an annular space to the debris removal tool entrance for debris removal.
