Abstract
Un sistema de cierre del interior del pozo para barrenas de perforación de conos giratorios incluye un cabezal de sello con un ancho mayor que su profundidad. En una implementación el cabezal de cierre incluye una saliente a lo largo de su base, sobre la cual se asienta un elemento de cierre. El elemento de cierre es un único elemento de cierre anular, con una hendidura formada en este, de forma que defina dos lóbulos. El elemento de cierre se asienta en el cabezal, de forma que la hendidura engrane con la saliente. Los lóbulos funcionan como elementos de cierre separados, aunque son un único elemento de cierre dispuesto en un único cabezal.
