Abstract

"PROCESSO PARA MIGRAçãO DE TEMPO DE PRé-EMPILHAMENTO DE TRAçOS DE DADOS SìSMICOS DE DESLOCAMENTO COMUM". Um processo para migração de tempo de pré-empilhamento de traços de dados sísmicos de amplitude controlada. De acordo com o processo inventivo, conjuntos de dados de deslocamento comum de pré-empilhamento de traços de dados sísmicos (66) sofrem transformada de Fourier 3-D do domínio espaço tempo para um domínio de dados alternativos pré-selecionado, tal como o domínio de freq³ência-número de onda (68), o domínio número de onda-tempo, ou o domínio inclinação/empilhamento. Um operador de migração (64) que preserva substancialmente as amplitudes sísmicas dos traços de dados originais é computado no domínio p-z. Este operador de migração (64) é aplicado aos, traços de dados transformados no domínio de dados alternativos (68), uma condição de imagem é aplicada (70), e os traços de dados migrados resultantes são então transformados de volta para o domínio do espaço (72).
