摘要:
A fully electric tool for continuous downhole flow control is described, said tool comprising a body and along the said body, actuating set(s), each actuating set comprising a passage system comprised of shaft(s) radially disposed along said cylindrical body, each of said shaft (s) being actuated with its opposed pair or in an independent way in a well-defined position or not, said shaft(s) being provided of spherical element(s) or sphere(s), provided of at least one window forming piles of sphere(s) in shaft(s), the rotation of said shaft(s)(108) of piles of sphere(s) enabling the opening or total or partial obstruction of holes by the total or partial coincidence of said window(s) of sphere(s) with said bore(s) of said cylindrical body.
