摘要： A downhole tool for removing debris from a wellbore comprises a body having a bore, a collection member, and a means for creating a hydraulic barrier within a wellbore annulus. The hydraulic barrier within the wellbore annulus restricts upward movement of a debris laden fluid within the wellbore annulus causing the debris laden fluid to be directed toward the collection member. Thus, the hydraulic barrier facilitates removal of debris from the wellbore.
摘要翻译：用于从井眼去除碎屑的井下工具包括具有孔的主体，收集构件以及用于在井眼环内产生液压屏障的装置。井筒环内的液压屏障限制了井筒环内的载满碎屑的流体的向上运动，导致碎屑流体被引向收集构件。因此，液压屏障有助于从井眼去除碎屑。

摘要： A downhole tool for removing debris from a wellbore comprises a screen member, an incoming fluid accelerator, and a cavity for capturing debris. The incoming fluid accelerator is disposed above the screen and accelerates the flow of an incoming fluid through the accelerator and into a screen bore. The incoming fluid then exits the bottom of the tool, mixes with wellbore fluid containing debris to form a combination fluid that is transported upward within the wellbore annulus. A pressure differential between the incoming fluid flowing within the screen bore and the wellbore annulus pulls the combination fluid containing the debris into the cavity where the debris is captured. Fluid and/or debris not blocked by the screen flows through the screen into the screen bore to be circulated downward and out of the tool where it can pick up additional debris for capture.

摘要： A downhole tool for removing debris from fluid flowing through the downhole tool comprises a screen member and wiper member, the wiper member having at least one window disposed through the inner and outer wall surfaces of the wiper member. Either the screen member or the wiper member is rotatable such that rotation of the screen member or the wiper member causes debris disposed on the outer wall surface of the screen member to fall-off the screen member. At least one directional port disposed at either the upper end of the screen member or the upper end of the wiper member causes rotation of the screen member or wiper member when fluid flows through the downhole tool.

摘要： An administrator of an enterprise storage set may be tasked with storing a large number and variety of data sets on a large number and variety of storage components. However, the manual selection of a physical schema by an administrator may be time-consuming, may generate inefficient physical schemata, and may not be easily reevaluated as the data sets and storage set change. Presented herein are techniques for automatically determining a physical schema by comparing the storage factors of each data set (e.g., data size, relationships with other data sets, and usages of the data set by users) with the storage capabilities of the storage components, selecting a suitable storage component, and implementing the storage of the data set on the storage component. An embodiment of these techniques may thereby achieve an automated identification of a physical schema with improved efficiency and flexibility of the physical schema while conserving administrative resources.
摘要翻译：企业存储集的管理员可以负责在大量和多种存储组件上存储大量和多种数据集。然而，由管理员手动选择物理模式可能是耗时的，可能产生低效的物理模式，并且可能不会随数据集和存储集改变而容易地重新评估。这里提出的技术是通过将每个数据集的存储因子（例如，数据大小，与其他数据集的关系以及用户的数据集的使用）与存储组件的存储能力进行比较来自动确定物理模式，选择合适的存储组件，以及在存储组件上实现数据集的存储。因此，这些技术的实施例可以实现物理模式的自动识别，同时节省管理资源，同时提高物理模式的效率和灵活性。
