Abstract:
A valve-type electric tool for downhole flow control using a holo-shaft motor. Said valve comprises: a housing provided with an infinitely variable choke where in seals work as gaskets both the outside and inside of the valve; a hollow-shaft servomotor inside said housing attached to a nut, and, additionally, when said motor is activated, the motor directly moves a sliding sleeve provided with an infinitely variable choke axis-wise said valve; and in which the movement of said motor is generated by of a spindle, created on the very same said sliding sleeve, and in which said valve is operated from the surface by a single electric cable.
