    • The invention is an assembly which is run into the wellbore to straddle pre-existing control line connections used normally for actuation of a sleeve for a single subsurface safety valve. The lower flapper is closed through the use of one of the control lines. It is then tested against formation pressure to make sure that it holds. Upon determination that the lower flapper is holding, the upper flapper is shut off using the other control line. By adding additional pressure to the control line for the lower sleeve, further movement of the lower sleeve is obtained to urge another sleeve into contact with the upper flapper to provide support for it so that it can be tested from above. Once the two flappers have been tested, uphole assembly in the wellbore can begin through the wellhead in the zone above the tested valves once assembled. Coiled tubing or wireline can be advanced sealingly through the wellhead as the assembly is lowered past the flappers which are now allowed to open. The flapper assembly is eventually removed.
    • 本发明是一种组件,其进入井眼以跨越预先存在的控制线连接,通常用于致动用于单个地下安全阀的套筒。 通过使用其中一条控制线将下挡板关闭。 然后根据地层压力进行测试,以确保其保持。 在确定下挡板保持时,使用其他控制线切断上挡板。 通过向下套管的控制线增加额外的压力,获得下套筒的进一步运动,以促使另一个套筒与上挡板接触,以便为其提供支撑,从而可以从上方进行测试。 一旦两个襟翼已经被测试,井筒中的井眼组装可以一旦组装就可以通过被测阀门上方的井口开始。 当组件下降通过现在允许打开的挡板时,螺旋管或电缆可以密封地穿过井口。 挡板组件最终被移除。

    • A retrievable packoff assembly for temporarily sealing a well pipe and anchoring equipment at a subsurface location within the pipe. The assembly is connected to a tubular actuation tool which is manipulated from the surface to position the assembly at a subsurface well location, set the assembly and then release from the set assembly. Right-hand tool rotation sets the assembly, releases the tool, and is subsequently employed to reengage and unset the assembly for retrieval to the surface. A bypass flow passage in the assembly is controlled by a sliding sleeve valve which is automatically closed by the right-hand tool rotation during setting and release and automatically reopened by tool rotation occurring during retrieval of the assembly. Flow through both the assembly and the bypass is confined within the actuation tool. A control flow passage in the apparatus is sealed by a retrievable blanking plug which may be removed to permit passage of equipment through the anchored assembly. The sealed assembly holds pressure from above or below. Drill pipe or other equipment may be supported in the well pipe by the set assembly.
    • 一种可回收的包装组件,用于临时密封管道内的管道和锚定设备在管道内的地下位置。 组件连接到从表面操纵的管状致动工具,以将组件定位在地下井位置,设置组件然后从组件组件释放。 右手工具旋转设置组件,释放工具,并随后用于重新加装和拆卸组件以便检索到表面。 组件中的旁通流动通道由滑动套管阀控制,滑动套管阀在安装和释放期间由右手工具旋转自动关闭,并在组件取回期间由刀具旋转自动重新打开。 流过组件和旁路的流动被限制在致动工具内。 装置中的控制流动通道由可回收的冲裁塞密封,可以将其移除以允许设备通过锚定组件。 密封组件从上方或下方保持压力。 钻管或其他设备可以通过组件组装在井管中。

    • At least one three phase driven pumps (56) in a hydrocarbon well (10) well bore (12) uses frequency shift keyed digital signals (78) to pass instructions from a surface station (46, 26, 34, 30) to a tool (14, 76, 56) and reports from a tool (14, 76, 56) to the surface station (46, 26, 34, 30) in common mode through the three phase cables (16) using a star point (58) of the three phase cables (16) after each pump as the signal transmission and reception point and as the point for coupling a DC Power supply (28), also provided in common mode on the three phase cables (16), to the down hole electronic equipment (72 76). The surface equipment (46) and the tool (14) use as a common ground.
