摘要： A sensor and transmitter is employed with a pressurized chamber of a downhole tool to be able to tell at a glance when the tool is delivered for service that it is properly charged. The sensor and transmitter can be integrated within the tool so as to be protected from damage during run in. While in service the sensor and transmitter can monitor pressure in real time and include a capability to send surface signals for real time monitoring of chamber pressures corrected for the service depth, temperature and density of the hydraulic fluid, for example. The signal can be acoustic through the control line or the annulus or delivered through a fiber optic cable or signal wire run in the hydraulic control line, an auxiliary line or through the annulus.

摘要： A control system for a subsurface safety valve references the surrounding annulus to put the operating piston in pressure balance. Depending on the configuration and which seal in the system fails, the various embodiments can differ in their failure modes. With the lower end of the piston exposed to annulus pressure all failure modes close the flapper. With the lower end of the piston exposed to tubing pressure, failure of any of the seals except one will result in flapper closure.

摘要： A wellbore cleanup tool collects debris when moved in one direction downhole. A flow diverter is extended for such flow diversion when debris is collected. When running the tool in the opposite direction in the wellbore, the flow diverter is in whole or in part articulated to retract so as to reduce resistance to fluid that passes around the outside of the tool. A segmented diverter can have fixed and movable components that are guided. The movable components can become longitudinally offset from the fixed components for movement in the direction where maximum flow bypass around the outside of the tool is desired. In an alternative embodiment, the diverter segments can all be movable on an inclined track to retract against a bias force for fluid bias with movement of the tool in the opposite direction allowing the bias to push the segments on the inclined track for diversion of debris laden fluid into a capture volume in the tool.

摘要： Casing or other well tubulars that have failed are repaired in a manner that doesn't reduce the final inside diameter and doesn't further propagate the failure. The tubular needing repair is first expanded on at least one zone above and below the damaged area. This expansion in an undamaged area arrests failure propagation when the damaged area is then expanded. After the damaged area is expanded, the patch coupled preferably with exterior seals is positioned in the expanded zone of the damaged tubular and expanded. The procedure can also be accomplished in a single trip into the well.

摘要： Disclosed herein is a method to facilitate establishing a connection between an access-seeking device and an access granting device. The method may include receiving, using a communication device, a Quantum Level Security (QLS) code from the access-seeking device. Further, the QLS code may be generated by the access-seeking device based on at least one QLS function and at least one parameter. Further, the method may include receiving, using the communication device, an independent QLS code generated by an access granting device based on the at least one QLS function and the at least one parameter. Further, the method may include comparing, using a processing device, the QLS code and the independent QLS code. Further, the method may include establishing, using the communication device, the connection between the access-seeking device and the access granting device based on a result of the comparing.

摘要： A subterranean tool that is self contained for actuation can be run into a desired location on an automatic set mode controlled by a timer. If a problem develops in getting the tool to the desired location in time a magnetic field created by permanent or electro-magnets can be brought to bear on the tool to stop the timer before the tool actuates. Once the tool is subsequently positioned at the desired location another magnetic field can be brought to bear near the tool to set it. Alternatively, the tool can be run to the desired location without activation with the timer and then the magnetic field can be brought to the tool to set it. The magnetic field can be lowered to the tool with wireline or can be dropped or pumped past the tool to actuate the tool. Optionally the field can be generated from within an object that ultimately lands on a seat to provide a backup way to set the tool using tubing pressure.
摘要翻译： 可自动装载用于致动的地下工具可以在由定时器控制的自动设定模式下运行到期望的位置。 如果工具在时间上到达所需位置时出现问题，则永久磁铁或电磁铁产生的磁场可以在工具启动之前停在定时器上。 一旦工具随后定位在所需位置，可以使工具附近的另一个磁场保持固定。 或者，可以将工具运行到期望的位置，而不用定时器激活，然后磁场可以被带到工具来进行设置。 磁场可以用电缆下降到工具，或者可以通过工具掉落或泵送，以致启动工具。 可选地，该场可以从最终落在座位上的对象内产生，以提供使用管道压力设置工具的备用方式。

摘要： The removable plug features a solid material that is housed in a porous container that has its shape changed to transition from the run in shape to the set shape. A swage is moved through a passage in the container to enlarge the passage and move the container to a borehole wall. The passage is then closed such as with a flapper valve or by moving in a mandrel into the expanded passage and lodging the mandrel in the expanded passage. Various release techniques are described.

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.
摘要翻译： 用可延伸和旋转的刀片切割的管状切割器在穿过要切割的管状物时，其切割深度受到限制。 在优选实施例中，管状物具有外部的松散安装的构件以与旋转刀具接合。 当这种接合发生时，效果是松散安装的构件用作切割器的盖子，以防止它们切割超过待切割的管状物的其他结构。 松散安装的构件被旋转叶片抓住用于串联旋转，这防止了进一步的切割动作。 磨机上的负载显着下降，使得表面人员具有停止对驱动机构的液压的信号，以允许叶片缩回并且切割器被移除。

摘要： A fracturing jet nozzle assembly features a series of angles nozzles on a rotatably mounted plate that operates in conjunction with a central nozzle or nozzles. The slanted nozzles are aimed into the perforation where the central nozzle is aimed directly so that the rotation of the nozzle plate from the slanted nozzles results in cyclic impacts in the perforation from where the fractures will propagate. The cyclic loading results in greater fracture formation and propagation. In another variation, relatively movable plates employing slanted nozzles rotate one plate with respect to another to get the effect of cyclic pulses of jetting fluid impingement in the perforation to enhance formation and propagation of fractures from the perforation.
