Abstract

"MéTODOS DE PROCESSAR DIAGRAFIAS DE DECAIMENTO DE TEMPO PARA AUMENTAR A RESOLUçãO VERTICAL E DE AUMENTAR A RESOLUçãO DE MEDIçãO". Um método de otimizar a resolução de medição é apresentado. Em uma concretização, o método inclui (1) obter múltiplas amostras de medição em cada uma de múltiplas posições ao longo de um furo de sondagem; (2) extrair amostras de índice de referência do conjunto de amostras de medição; (3) determinar uma diferença entre cada uma das amostras de índice de referência e correspondentes amostras de índice modeladas; e (4) atualizar um conjunto de amostras de índice otimizadas baseado sobre a diferença. As amostras de índice são de preferência selecionadas para serem representativas das amostras de medição obtidas em cada posição, e conseguinte, podem ser selecionadas das amostras de medição, ou alternativamente, podem ser médias das amostras de medição. As amostras de índice modeladas supra mencionadas podem ser determinadas a partir da aplicação de uma resposta de ferramenta predeterminada às amostras de índice otimizadas, que por sua vez, podem ser determinadas por iteração. Uma vez que a diferença tenha sido reduzida abaixo de algum valor limiar, a relação entre as amostras de índice otimizadas e as amostras de índice de referência pode ser usada para calcular um filtro de deconvolução para todas as amostras de medição originais provenientes do furo de sondagem. Quando aplicado às amostras de medição originais, o filtro de deconvolução produz amostras de medição tendo uma resolução otimizada.
