Abstract

"SISTEMAS PARA GERAR UM SINAL, PARA ENVIAR SINAIS BIDIRECIONAIS SIMULTâNEOS E DECODIFICAR UM SINAL DE PULSO DE PRESSãO, E, MéTODOS PARA COMUNICAçãO COM UMA MONTAGEM SUBSUPERFICIAL, PARA OBTER COMUNICAçãO BIDIRECIONAL SIMULTâNEA, PARA PERFURAR UM FURO DE SONDAGEM, PARA TRANSMITIR UM COMANDO DE COMPUTADOR, PARA ENVIAR SINAIS DE INSTRUçãO POR ENLACE DESCENDENTE SEM INTERROMPER A PERFURAçãO, PARA AUMENTAR OU DIMINUIR A VELOCIDADE DE DADOS DE SINALIZAçãO POR ENLACE DESCENDENTE, PARA OBTER UMA VELOCIDADE DE DADOS EFETIVAMENTE ALTA DE SINALIZAçãO POR ENLACE DESCENDENTE E PARA OBTER SINALIZAçãO POR ENLACE DESCENDENTE E ENLACE ASCENDENTE COM ALTA VELOCIDADE DE DADOS". A invenção descreve sistemas de telemetria de enlace descendente provendo aparelhos e métodos aperfeiçoados para comunicar instruções via pulsos de pressão de equipamento de superfície para uma montagem no furo de sondagem. O sistema compreende um transmissor de superfície (6) para gerar pulsos de pressão, um sistema de controle (90), e um receptor no furo de sondagem (21) para receber e decodificar pulsos. Em operação, uma válvula de desvio (7) é aberta e fechada para criar uma série de pulsos de pressão recebida e decodificada por um receptor no furo de sondagem (21). O método reduz significativamente o tempo necessário para comunicação por enlace descendente sem interromper a perfuração e sem interromper comunicações por enlace ascendente, de modo que comunicações simultâneas, bidirecionais, sejam possíveis se os sinais por enlace descendente e enlace ascendente forem enviados a diferentes freq³ências. O esquema de telemetria e algoritmo provê um método inventivo para filtrar e decodificar os sinais por enlace descendente. O algoritmo determina os intervalos de tempo entre picos de pulso e decodifica os intervalos em uma instrução. O algoritmo também inclui checagem de erro para verificar se a instrução foi recebida no furo de sondagem apropriadamente.
