Abstract

APARELHO E MéTODO PARA TRANSMITIR SINAIS A PARTIR DA SUPERFìCE DE UM POçO PARá UMA LOCALIZAçãO FURO ABAIXO. Um aparelho para um método para transmitir sinais a partir da superficie de um poço para uma localização no interior do utiliza um sensor de pressão de fluido no furo abaixo (52), um dispositivo de processamento de sinal (54; 56; 58) localizados no furo abaixo em conexão elétrica com o sensor de pressão (52) e uma unidade de lógica programável (60) capaz de contar pelo menos dois sinais recebidos pelo sensor de pressão no furo abaixo (52). Geralmente, sinais de transmissão a partir da superficie incluem um pico na pressão do fluido no furo abaixo localizado no curso da tubulação de produção dentro de um furo de poço e esses sinais são sensoreados pelo sensor de pressão de fluido no furo abaixo (52). Geralmente, sinais transmitidos da superficie incluem um pico na pressão do fluido no furo abaixo localizado no curso da tubulação de produção dentro de um poço e esses sinais são sensoreados pelo sensor de pressão do fluido no furo abaixo (52). A unidade de lógica (60) emite um sinal para uma ferramenta a ser atuada se ela recebe um número de sinais dentro de um período de tempo particular, em que a unidade de lógica (60) atua a ferramenta pela freqüência dos sinais recebidos ao invés da amplitude dos sinais recebidos.APPARATUS AND METHOD FOR TRANSMITTING SIGNS FROM THE SURFACE OF A WELL TO A LOCATION HOLE BELOW. An apparatus for a method for transmitting signals from the surface of a well to an interior location utilizes a fluid pressure sensor in the bore below (52), a signal processing device (54; 56; 58) located on the down hole in electrical connection to the pressure sensor (52) and a programmable logic unit (60) capable of counting at least two signals received by the pressure sensor in the hole below (52). Generally, surface-to-surface transmission signals include a peak in fluid pressure in the bore below located in the production piping course within a wellbore and these signals are sensed by the fluid pressure sensor in the bore below (52). Generally, surface transmitted signals include a peak in downstream fluid pressure located in the production piping course within a well and these signals are sensed by the downstream fluid pressure sensor (52). The logic unit (60) outputs a signal to a tool to be actuated if it receives a number of signals within a particular time period, where the logic unit (60) actuates the tool by the frequency of the received signals instead. the amplitude of the received signals.
