Abstract
"PROCESSOS PARA MEDIçõES POR RESSONâNCIA MAGNéTICA NUCLEAR DE PROPRIEDADES PETROFìSICAS DE UMA FORMAçãO GEOLóGICA E PARA SEPARAçãO DE HIDROCARBONETOS DE SALMOURA EM MEDIçõES POR RESSONâNCIA MAGNéTICA NUCLEAR DE UMA FORMAçãO GEOLóGICA, E, APARELHO PARA MEDIR PROPRIEDADES PETROFìSICAS DE UMA FORMAçãO GEOLóGICA". Descreve-se um processo e um sistema para a separação de fases fluídas em medições por RMN realizadas em poço (107). A invenção é aplicável especificamente à separação de salmoura de hidrocarbonetos, utilizando difusão acentuada para estabelecer um limite superior para a distribuição espectral T2 da salmoura. Os parâmetros podem ser modificados para acentuar o relaxamento de difusão durante as medições incluem o espaçamento inter-eco TE e o gradiente de campo magnético G (110) da ferramenta de medição.
