    摘要: A subterranean well completion has a tubular structure in which a remote controlled robot is permanently disposed. The robot is self-propelled, programmable, receives instructions from and communicates data to the surface, and is adapted to receive power from a downhole source and perform a variety of well tasks such as, for example, positioning valves and other well tools and sensing the values of predetermined downhole parameters and relaying the sensed information to the surface. The robot, which is operable without physical intervention through the tubular structure to the robot, propels itself to a location in the tubular structure at which a desired well task is to be performed, performs the task and then parks itself in the tubular structure until another well task is to be performed by the robot.

    摘要: An apparatus for gravel packing a production interval (42) of a wellbore (32) comprises first and second sand control screen assemblies (56, 58) connected downhole of a packer assembly (46) and a cross-over assembly (40) that provides a communication path (74) downhole of the packer assembly (46) for a gravel packing fluid and a communication path (92) uphole of the packer assembly (46) for return fluids. A wash pipe assembly (66) extends into the first and second sand control screen assemblies (56, 58) forming an annulus (84) therebetween. A valve (70) is positioned within the wash pipe assembly (66) in a location between the first and second sand control screen assemblies (56, 58). The valve (70) is actuatable from a closed position to an open position when the beta wave (100) is proximate the location of the valve (70).
