摘要： An adjustable tubular string nose uses axially relatively movable wedge segments to form a variable diameter ring shape using technology described in US 7128146 in another context. The nose has a seat around a passage therethrough. After insertion of the nose into a first bore, typically a main bore, the nose is retracted out of the main bore and pressure against a seated bore in the nose expands the nose radially to a degree where re-entry into the main bore is precluded but entry into a lateral bore is still possible. The string advances onto a lateral no-go. This signals surface personnel to pick up and raise pressure to blow the seated ball through the seat to again open the passage in the nose. A seal stack behind the nose in advanced into a lateral seal bore and the treatment can then commence.

摘要： A fracturing tool features spaced releasable packers with an outlet in between. The housing has relatively moving components for opening the frac port between the packers with weight set on the lower packer. Once the frac port is opened the upper packer is set and the pumping begins. The upper packer can be released so that tension can be pulled on the lower packer to close the frac port and open a through passage in the housing. In one embodiment the through passage can be located above the lower packer to a sand jet perforator to clean debris away from the lower packer if it is difficult to release the lower packer or to abrasively perforate through a tubular. In another embodiment the housing outlet can be below bottom packer to perform a treatment further downhole or to operate another tool. The straddle tool can be run in on coiled tubing.
摘要翻译：
一种压裂工具具有隔开的可拆卸封隔器，其间具有出口。壳体具有相对移动的部件，用于打开位于封隔器之间的压裂端口，并在下封隔器上设置重量。一旦压裂端口被打开，上封隔器被设置并开始泵送。上封隔器可以被释放，使得下封隔器上的张力可以被拉动以关闭压裂端口并打开外壳中的贯通通道。在一个实施例中，如果穿过通道难以释放下封隔器或磨蚀穿孔穿过管件，则穿过通道可位于下封隔器上方至喷砂穿孔器，以清除远离下封隔器的碎屑。在另一个实施例中，壳体出口可以在底部封隔器的下方以进一步在井下进行处理或操作另一工具。跨接工具可以运行在连续油管上。

摘要： A dual barrier system is provided to withstand pressure differentials well above those of the check valves in a float shoe used to allow circulation of a bottom hole assembly on the way to a desired depth. The bottom hole assembly can have screens and an internal wash pipe that pushes a sleeve to hold open a lower flapper for running in. The wash pipe also holds open an upper flapper that has opposed orientation to facilitate circulation when running in. Once on location an annulus packer closes off the producing zones where the screens are located from a lower zone that can have higher pressures. A high pressure packer is set against the shoe track and the wash pipe is retracted through this packer. Retracting the wash pipe allows closure of both flappers. Flow is blocked in opposed directions by the flappers and packer in the shoe track.

摘要： A one trip method of cleaning a portion of the borehole and then setting a tool such as a packer or a bridge plug locates the cleanup tools above the plug with a ported sub to allow circulation of loosened debris. The debris is directed uphole from above the plug and does not have to pass around the sealing element of the plug or through bypass ports in the plug body. The plug is then positioned in the cleaned portion and set. The cleaning tools are released from the set plug and brought to the surface. These tools could be used to clean the portion of the borehole where the tool is set or clean the entire section above the tool on the trip out of the borehole. Cleaning tools can be filter, scrapers both fixed and movable, magnets, brushes and associated tools that centralize the assembly for more effective operation.

摘要： A well is abandoned by locating a plug in casing preferably at a location above where the quality of the cement job or the casing is questionable. A high powered laser is run in preferably on wireline and at a location above the plug is activated and rotated with the effect that the casing, cement behind the casing and the formation about the cement becomes molten and flows onto the plug where the mass cools and solidifies into a cohesive mass that spans the borehole and extends laterally into the formation. The mass is impervious and the abandonment procedure is complete. The plug can be bare or it can have layers above such as cement to protect the plug from molten temperatures until the mass cools sufficiently and solidifies.

摘要： A debris removal device for subterranean use features a debris laden inlet tube within a housing to define a debris collection space at the lower end of the housing. An eductor draws the debris laden fluid to the top of the inlet tube where the flow stream is returned to a downhole direction with discrete passages formed between the housing and the inlet tube by spaced parallel plates. The plates feature extending tabs on diametrically opposed lower ends of the plates. As a result flow heading back downhole can release debris and turn back uphole in passages defined between the outside of the plates and the inside wall of the housing. The tabs allow the flow turning uphole to make a greater radius turn because of a crossing over effect created by the tabs. There is less turbulence and narrower width to the flowing stream going uphole.
摘要翻译：用于地下使用的碎片去除装置在壳体内具有载满碎屑的入口管，以在壳体的下端限定碎屑收集空间。喷射器将载满碎屑的流体抽吸到入口管的顶部，其中流动流返回到井下方向，并且通过间隔开的平行板在壳体和入口管之间形成分离的通道。板的特征在于板的直径相对的下端具有延伸的突出部。结果，向下返回到井下的流动可以释放碎屑并在通过限定在板的外部和壳体的内壁之间的通道中向后回转。由于标签产生的交叉作用，这些突片允许流向上的孔进行更大的半径转弯。流向井的流动的波动较小，宽度较窄。

摘要： A downhole tool for removing debris from a wellbore comprises a mandrel and a shroud disposed around a portion of the mandrel. The mandrel includes at least one mandrel port in fluid communication with a mandrel bore. The shroud includes a cavity and a shroud port. Debris laden fluid is pulled into the shroud cavity by flowing fluid through the mandrel bore, out the mandrel port, into the shroud cavity, and through the shroud port. The debris-laden fluid is pulled into the shroud cavity due to a pressure differential created by the flow of the fluid through the mandrel port and out of the shroud port. As the debris laden fluid flows into the shroud cavity, the debris is captured within the tool.
摘要翻译：用于从井眼去除碎屑的井下工具包括围绕心轴的一部分设置的心轴和护罩。心轴包括与心轴孔流体连通的至少一个心轴端口。护罩包括腔和护罩口。通过使流体流过心轴孔，从心轴端口流入护罩腔，并通过护罩端口将碎屑载入流体拉入护罩腔。由于流体通过心轴端口并流过护罩端口而产生的压力差，将载满碎屑的流体拉入到护罩腔中。当载满碎屑的流体流入护罩腔中时，碎屑被捕获在工具内。

摘要： A bottom hole assembly for engaging and removing an object within a wellbore comprises a cutting tool at a lower end. Continued engagement of the cutting tool with the object is facilitated by an axial compression device disposed within the bottom hole assembly below the anchor of the bottom hole assembly. The axial compression device comprises a compressed position and an expanded or extended position. As the object is being cut or abraded, the axial compression device moves from the compressed position toward the expanded position so that a continued downward force is transferred to the object by the bottom hole assembly.

摘要： A lateral is gravel packed without a junction in place in a single trip into the wellbore. A disconnect is provided between the isolation packer in the lateral and a main bore packer. The inner string assembly in the gravel packing completion releases a disconnect with a shift tool and then releases the main bore packer so that the inner string assembly takes out the main bore packer and the upper portion of the disconnect when pulling out of the hole. A junction is then placed into the main and lateral legs with a packer having a seal bore into which the production string is sealingly stabbed to produce out of the main bore and/or the just completed lateral.

摘要： A frac plug mandrel assembly has an inner core that permits flow that is surrounded by a thin wall tube that distributes compressive loading, such as that applied by the set sealing element to the core. The core is a cylindrically shaped insert for inside the tube and allows flow until a ball or plug is landed on a seat to close off the flow through the core. The core can have a star pattern with a series of radially extending segments from a solid hub or a cylindrical shape of a honeycomb or other porous structure that has the requisite strength to resist collapse from compressive loading of the set sealing element while still allowing sufficient flow area for fluid displacement.
