Abstract

um método para transmitir dados a partir de uma localização de fundo de poço para uma localização na superfície da terra inclui determinar um valor mínimo e um valor máximo de amostras m de valores de dados, determinar um código para as amostras m de valores de dados que forneçam uma indicação dos valores máximo e mínimo das amostras m e codificar o código de tecla e os valores de dados em uma ou mais palavras codificadas. a uma ou mais palavras codificadas são, então, transmitidas como um sinal acústico no fluido de perfuração, modulando um impulsor de lama. o sinal acústico é recebido por um transdutor na subida do pulsador de lama e convertido em um sinal elétrico. o sinal elétrico é demodulado em uma palavra codificada recebida, que é descompactada nas amostras m de acordo com o código. as amostras m são então recebidas por um sistema de processamento de computador disposto como a superfície da terra.
