ROTATION LOCK TORQUE ANCHOR FOR A WELL PRODUCTION COLUMN, PUMP AND ROTATION LOCK SYSTEM, AND PUMPING FACILITY EQUIPPED WITH SUCH A TORQUE ANCHOR

摘要

the invention relates to an anchor pair (30) for blocking rotationa column output relative to a casing of a well for pumpingathe fluid, which is characterized in that it consists of:a fixture (36) designed to be mounted in the casing.- an internal channel (50) arranged in the frame (36).at least one cavity (52, 54, 56) in fluid communication with the channelinternally, the cavity extending in a radial direction.at least one anchor piston (38, 40, 42) to slide bythe frame (36) in the radial direction and to exert a torque on thethe casing (6), where the fluid being contained in the internal channel (50).the piston exerts a force on the anchor.the invention also relates to a pumping system and arotation, anda pump out facility equipped with such an anchor pair.
