    • 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.

    • A completion method isolates a lower zone while circulation at high rates takes place above to clean debris out of the wellbore. Pressure fluctuation sensitive equipment in a lower completion is isolated with a tubing valve during circulation. This further prevents debris from clogging inlet pressure passages to equipment below the isolation valve during circulation to get the debris out. After circulation the packer is unset and the tubing valve is opened and a wellbore filter tool directs well fluids through a screen and captures the debris as the string is pulled toward the surface.
    • 完成方法隔离较低的区域,同时高速率的循环发生在上面以将井眼中的碎屑清除。 压力波动较敏感的设备在循环过程中与管阀隔离。 这进一步防止了在循环过程中,杂物将入口压力通道堵塞到隔离阀下方的设备以使碎屑流出。 循环后,打包机未开启,油管阀打开,井筒过滤器工具将井液流经筛网,并将柱塞拉向表面时捕获碎屑。

    • A direct access storage device (DASD) cage holds a DASD sled which contains an electronic DASD. The sled has a base plate, side walls and a front portion. The cage has side walls and a forward panel. Each side wall of the cage has a groove for receiving an outer edge of the base plate. The front portion interfaces the DASD with a machine connector. The sled has a slidable handle and a pair of pivotable latches which engage the handle. Each latch has an inner finger and an outer finger. Each inner finger engages a slot in the handle while each outer finger moves inward and outward. Stops in the base plate limit the travel of the inner fingers. The handle is pulled rearward to a disengaged position before the sled is installed in the cage. The outer edges of the base plate are placed in the grooves and the sled is pushed forward into the cage. When the sled is half-way into the cage, the latches will partially engage the grooves to stop the movement of the sled. From this position and by pushing the handle forward, the inner fingers are pushed forward by the slots in the handle so that the outer fingers rotate into engagement with profiles in the grooves and the DASD is connected to the machine connector. The sled is removed by pulling the handle rearward so that the outer fingers disengage the profiles. As the sled is removed from the cage, the DASD simultaneously disengages the machine connector.
    • 直接存取存储设备(DASD)保持架包含电子DASD的DASD滑板。 滑板具有底板,侧壁和前部。 笼子有侧壁和前面板。 保持架的每个侧壁具有用于接收基板的外边缘的凹槽。 前面部分将DASD与机器连接器相连接。 滑板具有可滑动的手柄和一对可旋转的闩锁,其与手柄接合。 每个闩锁具有内指和外指。 每个内指接合手柄中的狭槽,而每个外指向内和向外移动。 底板中的停止限制内指的行程。 在将雪撬安装在笼中之前,手柄向后拉到脱离位置。 基板的外缘放置在槽中,并将滑板向前推入保持架。 当雪橇进入笼子时,闩锁将部分地接合凹槽以停止滑板的移动。 从该位置并且通过向前推动手柄,内指由手柄中的槽向前推动,使得外指旋转成与凹槽中的轮廓接合,并且DASD连接到机器连接器。 通过向后拉动把手来移除滑板,使得外手指脱开轮廓。 当滑板从笼中取出时,DASD同时脱开机器连接器。
