Abstract

Un método para registrar y pre-procesar senales de datos sísmicos de alta fidelidad generadas por una pluralidad de fuentes sísmicas vibratorias en elcual las senales de datos sísmicos son recibidas desde detectores sísmicos, caracterizadoporq ue comprende medir el movimiento de cada una de las fuentesvibratorias que está relacionado con la fuerza aplicada por el vibrador multiplicado por una función de transferencia de sistema lineal, causal, defase mínima; relacionar lasalida re al del vibrador con el movimiento de vibrador medido; separar las senales de datos sísmicos vibratorios de acuerdocon la fuente generadora; determinar una relación dividiendo las senales de datos sísmicos vibratorios por elmovimiento medi do de cada fuente vibratoriapara eliminar la fuerza aplicada desconocida dejando la reflectividad de la tierra multiplicada por una derivada con respecto al tiempo dividida por unafunción de fase mínima. El método puede tambiénincluir deconvoluc ión de conjunto de tiro, deconvolución de conjunto receptor, corrección de estáticas,filtrado F-K de ruido, deconvolución de picos de fase cero y desfasaje de modelo. Una senal directamente proporcional a la senalreal que el vibradorest á enviando al suelo es usada en el pre-procesamiento. El movimiento del vibrador es medido para proveer una senal que es usada para procesar losdatos. Los datos son divididos por la senal relacionada con la senal real transmitida en el dom inio de la frecuencia.
