摘要

Summary "system to activate multiple tools of a well bottom, method for activating multiple load devices at the bottom of the well and system to activate multiple load devices at the bottom of the well bi-directional" a system to selectively activate multiple Devi You load, such as machine tools of wells.Which are selectively actuated by applying a predetermined voltage by a predetermined pair of the conductors. At least one locking device is associated with each load device. The locking device prevents the flow of current through the load device until the voltage across the pair of conductors exceeds a predetermined minimum.A method is provided for the selection of tools for the drive shaft by means of the application of minimum voltage through a set of drivers and a blocking device. Routes parasites are prevented from flowing current to the locking devices.A system is provided for the application of power to the load devices of a two-way, such as pumps and motors downhole. 1
