Abstract
Downhole flow control valves include a valve assembly, driven gear, drive gear, and motor. The valve assembly includes an outer sleeve and inner sleeve. The outer sleeve has openings and a fixed guide. The inner sleeve is disposed within the outer sleeve and includes an outer surface and an axially abutting surface defining a stair-stepped pathway. The fixed guide abuts against the axially abutting surface. The abutment of the fixed guide against the axially abutting surface of the inner sleeve causes the inner sleeve to translate axially between an open position and a closed position relative to the outer sleeve when rotated through operation of the motor, drive gear and driven gear. Systems for controlling fluid flow from lateral branches of a multilateral wellbore include at least a plurality of the downhole flow control valves and a downhole electrical power source for generating electrical power to operate the motor.
