Abstract

resumo patente de invenção: "medições de resistividade de formação utilizando correntes de fase controlada". a presente invenção refere-se a um aparelho para a estimativa de uma propriedade de uma formação de terra penetrada por uma perfuração de sondagem. o aparelho inclui um transportador configurado para ser conduzido através da perfuração de sondagem e tendo um primeiro eletrodo transmissor configurado para injetar corrente elétrica na formação e um primeiro eletrodo de medição configurado para receber corrente elétrica para a medição, devida à injeção de corrente a fim de avaliar a propriedade da formação de terra. um controlador é configurado para determinar uma diferença de fase entre corrente elétrica injetada e corrente elétrica recebida. um primeiro amplificador bucker é acoplado ao primeiro eletrodo de medição e configurado para aplicar uma tensão ao primeiro eletrodo de medição com base na diferença de fase determinada, a fim de que uma fase da corrente recebida pelo primeiro eletrodo de medição esteja substancialmente em fase com a corrente injetada pelo primeiro eletrodo transmissor.
