摘要： Introduced herein are a flow control system and a method for operating the flow control system that autonomously controls an inflow of fluid into production tubing in a wellbore based on conductivity or resistivity of the fluid that tries to enter the production tubing. By letting the conductivity of the fluid to open and close the control circuit that controls the operation of the actuator, the introduced flow control system is able to automate the inflow control of the fluid and minimize a number of electric components required. With a reduced number of electronics, the introduced system is more robust, reliable and stable in the extreme conditions inside a wellbore than other conventional flow control system.

摘要： A method of actuating a selected electrically powered device such as a solenoid operated valve (SOV) among a plurality of electrically powered devices coupled between a first conductor and second conductor includes applying a high voltage differential between the first conductor and the second conductor, the high voltage being at least as high as the breakover voltage of a switching thyristor coupled to the selected electrically powered devices. The method also includes applying a low voltage differential between the first conductor and the second conductor after applying the high voltage, the low voltage being lower than the breakover voltage of any switching thyristor coupled to the plurality of electrically powered devices.

摘要： A system includes a tool mandrel securable to a landing nipple and a prong receptacle coupled to a lower end of the tool mandrel. The prong receptacle includes a central bore and a pressure release port in communication with the central bore. The system also includes an equalizing prong initially securable within the tool mandrel in a run-in position. Further, the system includes a tubular prong extension coupled to the equalizing prong. An upper end of the tubular prong extension extends up out of the tool mandrel. Moreover, axially downward movement of the tubular prong extension from the run-in position to a set position secures the tool mandrel to the landing nipple, and axially upward movement of the tubular prong extension from the set position to a released position disengages the tool mandrel from the landing nipple.
