Fully electric tool for continous downhole flow control

A fully electric tool for the continuous downhole control of fluid flow, said tool being characterized by comprising:

• a) a body conceptually cylindrical, the superior and inferior ends of same being connected to the production string by means of threaded connections respectively, said body comprising an outer wall or cover, said body being provided with bore(s) provided with a seal seat and an opposition base, said bores being designed to allow the passage of fluid between the production string and the well annular, said cylindrical body including further ultrasonic oscillators;
• b) along the body of a), actuating set(s), each actuating set comprising:
• b1) a passage system formed by shaft(s) parallel to the axis of production string, said shaft(s) being radially disposed along said cylindrical body, each of said shaft operating with its opposed pair or independently in a well-defined position or not, said shaft(s) comprising spherical elements provided of at least one window, forming piles of spherical elements in direct and constant contact with the said seal seat s, the rotation of said shaft(s) of piles of spheres enabling the total or partial opening or closure of said bores by the total or partial coincidence of said window (s) of said spheres with said bores of said cylindrical body, in a continuous control of opening or closing of said window(s);
• and
• b2) In order to operate the passage system, a driving system formed by an electro mechanical device selected among a motor to generate the rotation movement of said shaft of piles of spheres and wherein each passage system of b) relies on a driving system of its own to secure independent rotation of same relative to any other shaft, in this way characterizing the independence of each of said actuating set, and wherein said motor, encapsulated by a housing copes structurally with differential pressures above 1,400.00 kgf/cm2 at temperatures around 200° C.;
• c) an electronic module in charge of i) taking an electrical supply cable and splitting same in a first and a second portion, the first (multiplexed) portion designed to the supplying of motors and sensors, the second portion being designed to the continuation of the supplying line and sensing of the remaining production line;
• and wherein i) the contact among said seal seats and said window(s) of said sphere(s) makes or destroys a physical communication between said production string and the well annular to allow or block the flow of fluid;
• and ii) a head-end travel limit located at the shaft of the spheres enables the positioning control of said window(s) in the mechanical mode, from which it is possible to measure the twist of said shaft.
