Abstract

Un cuerpo de estabilizador es llevado giratoriamente por un vástago estabilizador, en donde el cuerpo de estabilizador permanece substancialmente estacionario en relacion con el barreno conforme gira la cuerda de perforacion; por lo menos una cuchilla estabilizadora es llevada por el cuerpo de estabilizador, la cuchilla estabilizadora es radialmente extendible desde el cuerpo de estabilizador y hasta su acoplamiento con la pared lateral del barreno; cada cuchilla estabilizadora es extendible y retraible del cuerpo estabilizador independientemente de las otras, cada una de las cuchillas es guiada en ranuras con fondo inclinado y desviada a lo largo del fondo por medio de un motor electronico, los motores están alimentados por baterías que se cargan mediante acoplamiento inductivo de con bobinas de carga llevadas por el vástago estabilizador; el movimiento de las cuchillas está controlado ya sea mediante telemetría desde la superficie o por medio de un sistema MWD:
