    • A method and corresponding apparatus for automatically enabling and disabling an Optical Network Terminal (ONT) to communicate upstream with a network device, such as an Optical Line Terminal (OLT), is provided. The ONT includes at least one timing mechanism to time a duration of the ONT's being in an enabled or disabled state of upstream communications. After a timing mechanism times a desired duration, the ONT automatically changes between states of upstream communications (e.g., from enabled state to disabled state). The ONT may alternate between the enabled and disabled states of upstream communications until communications are established with the OLT. This method and corresponding apparatus prevent prolonged installation time because a technician can install the ONT without consideration of the ONT's state of upstream communications.
    • 提供了一种用于自动启用和禁用光网络终端(ONT)与诸如光线路终端(OLT)等网络设备进行通信的方法和对应的装置。 ONT包括至少一个定时机制,以使ONT的持续时间处于上行通信的启用或禁用状态。 在定时机制乘以期望的持续时间之后,ONT在上行通信的状态(例如,从使能状态到禁用状态)之间自动改变。 ONT可以在上行通信的启用和禁用状态之间交替,直到与OLT建立通信。 该方法和相应的装置防止延长的安装时间,因为技术人员可以安装ONT而不考虑ONT的上行通信状态。

    • An iterative planning and monitoring method for drilling (and completing) difficult boreholes which avoids unnecessary risk or cost. The method provides multiple point value probability estimates of an indicator of drilling problems based upon a range of possible drilling variables, supplanting single point estimates. Expected drilling variables are perturbed within physically feasible bounds, and multiple estimates of the corresponding indicator values are made. The probability of each estimate is used to calculate the likelihood of an indicator of an unwanted condition. Mitigation measures are implemented if the probability of an unwanted condition exceeding a threshold value is unacceptable and the mitigated probability is reassessed. If the perturbed indicator change is not significant, the drilling variable is deleted from further analysis. Critical variables are thus quickly identified, allowing monitoring and selection of mitigation measures which are the most cost effective. Unnecessary mitigation procedures or unwanted drilling risks are avoided by these procedures.
    • 钻孔(和完成)困难钻孔的迭代规划和监测方法,避免不必要的风险或成本。 该方法基于可能的钻井变量的范围提供钻井问题指标的多个点值概率估计,取代单点估计。 预期钻井变量在物理上可行的范围内受到干扰,并对相应指标值进行多次估计。 每个估计的概率用于计算不期望状况指标的可能性。 如果不想要的条件超过阈值的概率是不可接受的并且减轻的概率被重新评估,则实施缓解措施。 如果扰动指标变化不明显,钻井变量将从进一步分析中删除。 因此,快速确定关键变量,允许监测和选择最具成本效益的缓解措施。 这些程序避免了不必要的缓解措施或不必要的钻井风险。

    • A tube turning tool allows laterals to be drilled and completed without the need for articulated bending tools, underreaming, high fluid pressure, or a separate running of completion tools. The turning tool uses a rigid bent pipe section capable of being run downhole within many standard diameter well tubulars, supported in a desired position, and bending coil tubing at an ultra short radius of curvature as it is being run into the wellbore so that it can jet drill a lateral. After jet drilling a lateral, the lateral can also be completed using the coil tubing, e.g., gravel packed by pumping a slurry through the coil tubing while withdrawing the tubing from the lateral.

    • A hydraulic setting and release tool has a shear out setting assembly attached to a string coupling member. Upon reaching a predetermined hydraulic pressure, a piston of the tool shears restraining shear pins and moves in a body of the tool to release dogs that engage the coupling member. When used in running in a liner, the coupling member is a running head that rotates the liner during running in and cementing. When used as a drill string release tool, the coupling member is a release sub, the tool being placed serially with other string components. If the drill string gets stuck, it is separated by merely increasing the hydraulic pressure sufficiently to shear the pins and allow the piston to move and the dogs to retract to separate the release sub from the shear out assembly.
    • 液压设置和释放工具具有附接到弦耦合构件的剪切设定组件。 在达到预定的液压压力时,工具的活塞剪切约束剪切销并在工具的主体中移动以释放接合联接构件的卡爪。 当用于在衬套中运行时,联接构件是在运行和固井期间使衬管旋转的行进头。 当用作钻柱释放工具时,联接构件是释放子,该工具与其他串组件串联放置。 如果钻柱被卡住,则通过仅仅增加液压力来分离,以便剪切销并允许活塞移动,并且使爪缩回以将释放层与剪切组件分离。

    • A hydraulic setting and release system for run in and cementing of a work string and tubular within a borehole has a small diameter pipe string extending from a release tool through a packer to within the tubular. The system forms at least one annulus between the pipe string and tubular. The pipe string includes a ported nipple and a seat subassembly downstream of the ported nipple. The pipe string allows the packer to anchor the tubular, by being inflated through the port even when the seat is blocked. The pipe string also forms a flotation annulus which is sealed by, and the pipe string is supported by, a drag/seal subassembly downstream of the seat assembly. The system also includes a safety release tool for reliable uncoupling. Uncoupling is accomplished after run in, displacing a cement slurry slug separated by a plug or dart using a following pump down fluid which can land on the seat and block further flow and displacement of cement slurry, and anchoring. The release tool is then actuated uncouple the drill string from the cemented tubular and removal of the drill string prior to well operation (e.g., oil production).
    • 用于在钻孔内的工作串和管状件的运行和固井的液压设置和释放系统具有从释放工具通过封隔器延伸到管内的小直径管柱。 该系统在管柱和管之间形成至少一个环。 管柱包括端口乳头和位于移植乳头下游的座椅子组件。 管柱允许封隔器锚固管子,即使当座椅被阻塞时,其也通过端口充气。 管柱还形成浮动环,其由座椅组件下游的拖/密封子组件密封并且管柱由支撑件支撑。 该系统还包括一个用于可靠解耦的安全释放工具。 解耦是在运行之后完成的,使用以下泵送液体替代由塞子或飞镖分离的水泥浆料,其可以落在座椅上并阻止水泥浆料的进一步流动和移位以及锚定。 然后致动释放工具使钻柱从胶合管中脱离并在井操作之前移除钻柱(例如,产油)。
