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.

摘要： An electromagnetic-mechanical locking device applied to a subsurface safety valve comprising an electromagnetic-mechanical coupler formed electromagnet (4), ferromagnetic bulkhead (5) in solidarity to the mobile part (6), actuated by spring (9), in addition to locking element (7), and when activated, the electromagnet (4) creates a magnetic field that attracts the ferromagnetic bulkhead (5), along with the mobile part (6), moving this set towards the electromagnet (4), and compressing the locking element (7). During the movement, the mobile part (6) shifts the locking element (7) to the locking position, until it reaches its coupling on the flow tube (3), where it is maintained with compression locking element (7), configuring a trigger device. When the power supplied to the electromagnet (4) ceases, the electromagnetic attraction force of the ferromagnetic bulkhead (5) is cancelled, and the locking element (7), until then retracted, is distended, causing the return of the mobile part (6) to initial position.
