Abstract

Un aparato para medir la conductividad de formas terrestres penetradas por un pozo incluye un imán para inducir un campo magnético estático enformaciones terrestres penetradas por el pozo. El aparato incluye medios para generar un campo magnético de radiofrecuencia en el pozo y en lasformaciones terrestres, medios para de manera selectiva variar una frecuencia del campo magnético de radiofrecuencia, y medios para recibir una senal deresonancia magnética nuclear proveniente de núcleos excitados de dichas formaciones terrestres. Los medios de recepción incluyen medios para mediruna diferencia de fase entre la senal de resonancia magnética y el campo magnético de radiofrecuencia. La diferencia de fase medida está relacionadacon la conductividad de las formaciones terrestres.
