摘要： A system for use with a subterranean well can include a system controller with a computer, a power supply and at least one current sensor, multiple downhole well tools, each of the downhole well tools including a motor and a member displaceable by the motor; and an umbilical connected between the system controller and the downhole well tools, at least one conductor of the umbilical being connected to the motor of each of the downhole well tools. A downhole well tool example can include an actuator assembly configured to displace a member of the downhole well tool, the actuator assembly including a motor, a load yoke displaceable by the motor, and an elongated position indicator bar having at least one profile formed thereon. Friction between the load yoke and the position indicator bar varies as the load yoke displaces relative to the position indicator bar.

摘要： A valve assembly can include a housing having multiple longitudinally spaced apart ports, a sleeve longitudinally displaceable in the housing, and at least one deflector ring configured to block flow through an annular space formed between the housing and an outer surface of the sleeve. The deflector ring is positioned longitudinally between an adjacent pair of the ports. Another valve assembly can include a housing having a port, a sleeve longitudinally displaceable in the housing, and a nozzle having an orifice in communication with the port. The nozzle is secured to the housing.

摘要： A downhole tool, such an interval control valve, for use in a well has multiple motors and two drive assemblies to displace a yoke. A member, such as a sliding sleeve, of the downhole tool is connected to the yoke and can be actuated in response to the displacement of the yoke. The drive assemblies include first and second rotatable screws, and the yoke is disposed on the screws. Each motor can produce drive to rotate a respective screw. A respective gear is rotatable in association with at least the rotation of its associated screw. An intermediate gear is engaged between these two gears. The intermediate gear interconnects the rotation of the two screws forcing them to rotate at the same speed. Likewise, the intermediate gear balances the drive of the motors forcing the two screws to rotate at the same speed.
