Abstract
Aparatos y métodos para eliminar los efectos de pulsos de fluido de perforación de los sistemas de perforación direccional para permitir que un sistema de telemetría de pulso de lodo de MWD opere sin interferencia. La metodología se basa en la Promediación de Tiempo Sincrónico (STA). Con STA, cualquier fluctuación de presión que sea cíclica (sincrónica) con un evento mesurable puede perfilarse y sustraerse de manera subsiguiente de una señal de telemetría de pulso de lodo. La STA funciona al colocar un estroboscopio de tal manera que el estroboscopio se active para cada evento cíclico. El evento cíclico en esta descripción es una (o más) revoluciones de la sarta de perforación. Si existe una fluctuación de presión que se correlacione con ese evento cíclico, se identificará por un perfil estable de esa fluctuación de presión. Este perfil de presión entonces se utiliza para iluminar la fluctuación de presión cíclica de la señal de telemetría de pulso de lodo de entrada por lo que permite una operación normal del sistema de telemetría de pulso de lodo.
