Abstract

um aparelho de ressonância magnética nuclear para estimar propriedades de uma formação de terra inclui um transportador configurado para ser implantado em um poço na formação de terra e pelo menos um conjunto de transmissão disposto no transportador e configurado para gerar um campo magnético oscilante em um volume de interesse dentro da formação da terra. o aparelho também inclui pelo menos um conjunto de recepção disposto no transportador e configurado para detectar um sinal de ressonância magnética nuclear (nmr) se originando no volume de interesse. neste aparelho, o conjunto de recepção inclui pelo menos uma primeira região longitudinal com uma bobina de laço e uma bobina borboleta, o eixo central da bobina de laço estando localizado sobre uma região do conjunto de ímã onde um campo magnético estático está predominantemente ao longo de uma direção azimutal para o transportador e a bobina borboleta sendo pelo menos parcialmente sobreposta com a bobina de laço para reduzir acoplamento mútuo.
