Abstract

"FERRAMENTA DE REGISTRO". Uma ferramenta de resistividade de modo múltiplo para utilização em um sistema LWD inclui um projeto transmissor assimétrico com diversos transmissores (T~ 1~-T~ 5~) capazes de gerar sinais EM em diversas profundidades de investigação. Um sistema de no mínimo três receptores (R~ 1~-R~ 3~) é posicionado entre um sistema transmissor para detectar os sinais EM depois que eles tenham atravessado a região na vizinhança do furo de sondagem. No primeiro modo dois pares de receptores se combinam com o sistema transmissor assimétrico para produzir uma pluralidade de medições de resistividade compensadas. Em um modo alternativo, um par de receptores, constituido de um receptor de cada um dos pares precedentes, se combina com o sistema de transmissores para criar uma pluralidade de medições não compensadas. Esta capacidade de modo múltiplo habilita a ferramenta de resistividade a operar com sucesso em uma ampla variedade de formações de perfuração e sob um amplo escopo de condições de perfuração.
