Abstract

FERRAMENTA DE PERFILAGEM DE NÊUTRONS COM MÚLTIPLOS DETECTORES. Uma ferramenta de perfilagem de nêutrons tem múltiplos detectores espaçados em volta de circunferência da ferramenta. Os detectores são protegidos uns dos outros de tal maneira que cada detector detecta raios gama provenientes da área do furo de poço e da formação da qual ele será mais próximo. As leituras de perfil de cada detector posem ser associadas com a orientação desse detector. As leituras de perfil de orientações especificas podem então ser agregadas para formar um perfil azimutal que pode ser usado para analisar formações antes de fraturadas e/ou depois de fraturadas.
