Abstract

Perfeccionamientos en los sistemas de perforación rotativa con barrido de lodos por circulación inversa, caracterizados porque entra la barra de rotación y la sarta o varillaje de perforación, se incorpora una válvula principal que accionada por aire u otro fluido, obtura el conducto circulatorio de agua y/o lodos impidiendo su descarga al efectuar el cambio o colocación de un nuevo tramo de varillaje, manteniendo cebada la bomba en situación de paro.
