Abstract
Una cuerda de perforacion que termina en un broca de perforacion 3 es activada en un agujero; un fluido de perforacion de contenido de solidos reducido es bombeado a través de los tubos de perforacion y fuera de la broca, en donde el fluido de perforacion se golpea y desintegra material de formacion en cooperacion con la broca; un fluido anular que tiene una densidad mayor que aquélla del fluido de perforacion es bombeado continuamente dentro del anillo 5 entre el agujero y la cuerda de perforacion, en donde el fluido anular se extiende substancialmente desde la superficie hacia el fondo de la cuerda de perforacion; el fluido de perforacion y las cortaduras que resultan a partir de la desintegracion del material de formacion son regresados hacia la superficie a través de un pasaje tubular no obstruido substancialmente 17 en la cuerda de perforacion, el fluido anular se mantiene bajo una presion seleccionada y controlada en el anillo, en donde una entrecara se forma en la broca de perforacion en la cual el fluido anular se mezcla con el fluido de perforacion y es regresado junto con el fluido de perforacion y las cortaduras, y se evita substancialmente que el fluido de perforacion entre en el anillo.
