    • Remote operation of downhole tools in a subterranean wellbore is performed by inserting untethered, mobile devices sequentially into the wellbore. The mobile devices can include motive means, power supply, communication and data storage means, etc. In one embodiment, the method comprises maneuvering a first mobile device into proximity with a downhole tool, the device powering the tool. The first device is then removed, such as by flowing up or dissolving. The now-powered tool is used to perform a test or other operation. A second mobile device is maneuvered into proximity with the downhole tool and data is transferred. The second device is retrieved with the data or, using on-board logic devices, provides “if-then” commands to the downhole tool. Alternately, a third mobile device can be used to power and transfer commands to the tool. The method can be used for various tasks, such as opening bypass ports on ICD valves.
    • 通过将无阻塞的移动设备顺序地插入到井筒中来进行地下井眼中井下工具的远程操作。 移动设备可以包括动力装置,电源,通信和数据存储装置等。在一个实施例中,该方法包括使第一移动装置操纵靠近井下工具,该装置为该工具供电。 然后移除第一装置,例如通过向上或溶解。 现在供电的工具用于执行测试或其他操作。 第二个移动设备被操纵到靠近井下工具并且数据被传送。 使用数据检索第二个设备,或者使用车载逻辑设备向井下工具提供“if-then”命令。 或者,可以使用第三移动设备来向命令提供命令并传送命令。 该方法可用于各种任务,例如打开ICD阀上的旁路端口。
