Abstract

SISTEMA PARA A ATENUAçãO DE MúLTIPLAS DE FUNDO DE áGUA EM DADOS SìSMICOS GRAVADOS POR SENSORES DE PRESSãO E SENSORES DE MOVIMENTO DE PARTìCULAS. A presente invenção refere-se a um campo de onda de subida e um campo de onda de descida são calculados em uma posição de sensor a partir de um sinal de sensor de pressão e de um sinal de sensor de movimento de partículas (43,44). Então, um campo de onda de subida é calculado em uma posição de fundo de água substancialmente sem múltiplas de fundo de água a partir dos campos de onda de subida e de descida na posição de sensor. Em uma modalidade, o campo de onda de subida na posição de sensor é propagado para trás para o fundo de água, resultando em um campo de onda de subida no fundo de água (45). O campo de onda de descida na posição de sensor é propagado para frente para o fundo de água, resultando em um campo de onda de descida no fundo de água (46). O campo de onda de subida no fundo de água sem múltiplas de fundo de água é calculado a partir do campo de onda de subida propagado para trás no fundo de água, do campo de onda de descida propagado para frente no fundo de água e de um coeficiente de reflexão do fundo de água (48).
