Abstract

"ferramenta de perfilagem de microresistividade de fundo de poço, é método para fazer medições de perfilagem de anisotropia de microresistividade". uma ferramenta de perfilagem de microresestividade (100) inclui um eletrodo de injeção de corrente de monopolo (160) e pelo menos primeiro e segundo pares de eletrodos de potencial (212,214,226,228). a ferramenta (100) pode ainda incluir um controlador configurado para fazer medições de anisotropia de microresistividade usando um disparo único do eletrodo de injeção de corrente de manopolo (160). o controlador pode ser configurado para calcular um tensor bidimensional da resistividade da formação local a partir de um disparo único do eletrodo de injeção de corrente de monopolo (160). o uso de um disparo único tende a diminuir o tempo de medição que, por sua vez, tende a melhorar a detecção azimutal na imagiologia de anisotropia de microresistividade durante aplicações de perfuração.
