Abstract

Se describen las herramientas de RMN que tienen magnetización unidireccional a través del ensamblaje de imanes. Un ensamblaje de antena está posicionado alrededor del ensamblaje de imanes para excitar un volumen en la formación subterránea circundante. Una capa de material central magnético blando está posicionada bajo el ensamblaje de antena para cubrir todo o la mayor parte del campo de RF generado por la antena de RF de los componentes conductores dentro de la herramienta de RMN. Los componentes conductores pueden ser miembros estructurales conductores o un ensamblaje de imanes conductor. El material central magnético blando también da forma al campo magnético estático al suavizar la variación del campo magnético longitudinal.
