Abstract

En algunos aspectos, una herramienta de resonancia magnética nuclear (RMN) del fondo del pozo incluye un ensamblaje de imanes y un arreglo de antena. La herramienta de RMN puede operar en un pozo en una región subterránea para obtener datos de RMN de la región subterránea. El montaje de imanes produce un campo magnético en un volumen en torno al pozo. El ensamblaje de imanes incluye un imán central, un imán de piezas del primer extremo separado de un primer extremo axial del imán central, y un imán de piezas del segundo extremo separado de un segundo extremo axial del imán central. El ensamblaje de antena incluye una antena dipolo transversal. En algunos casos, las antenas dipolo transversales ortogonales producen excitación polarizada circular en el volumen alrededor del pozo, y adquieren una respuesta a partir del volumen mediante detección de bobina de cuadratura.
