Abstract

Un método para generar, registrar y pre-procesar datos sísmicos vibratorios de alta fidelidad en una disposición que usa una pluralidad de fuentesvibratorias, que incluye las etapas de medir el movimiento de cada uno de los vibradores, determinaru na relación dividiendo los datos sísmicos vibratoriospor el movimiento medido del vibrador para eliminar la fuerza aplicada desconocida dejando la reflectividad de la tierra multiplicada por unaderivada con respecto al tiempo dividida porun a función de fase mínima; filtrar con un filtro pasa banda de fase mínima la relación resultante yrealizar deconvolución de fase mínima para eliminar la derivada con respecto al tiempo dividida por la funsión de fase mínima. El métodotambi én puedeincluir las etapas de deconvolución de conjunto de tiro, deconvolución de conjunto receptor, corrección de estática, filtrado F-K para eliminar ruido,deconvolución de picos de fase cero, y desfasaje de modelo. Una senaldirect amente proporcional a la senal real que el vibrador está enviando a latierra se usa en el pre-procesamiento. El movimiento del vibrador es medido para proveer una senal que es usada para procesar los datos. Los datos sondivididos por unasenal re lacionada con la senal real transmitida en el dominio de la frecuencia.
