Abstract

Patente de Invenção: "TRANSMISSãO DE DADOS EM SISTEMAS DE OLEODUTO". Um primeiro conjunto de aparelho é disposto para transmitir dados de um ponto em uma seção fechada de um poço (1,3) para uma localização remota. O aparelho pode ser usado como uma estação de retransmissão (6) para aumentar a profundidade operacional. Os sinais são aplicados em e recebidos da corda (1) na estação de retransmissão (6) e um comprimento selecionado da corda (1) é fomecido com recurso espaçador isolante (9) em cada lado da estação de retransmissão para garantir que a corda (1) e o revestimento (3) fiquem efetivamente isolados por uma distância mínima selecionada. Isso possibilita que as diferenças de potencial sejam aplicadas a e detectadas da corda (1), assim possibilitando a transmissão e recepção dos dados. Um segundo conjunto de aparelho (figura 8) é disposto para transmissão de uma unidade interna (408) dentro de uma seção fechada do poço (401,403) para a área circundante imediata fora do revestimento (403). A unidade interna (408) injeta corrente na corda (401). Um toróide (415) que circunda o revestimento (403) é fornecido para captar sinais. As conexões espaçadas entre a corda (401) e o revestimento (403) são fornecidas por obturadores condutores (411). Uma desigualdade na corrente que flui na corda (401) e revestimento (403) é gerada, de forma que um fluxo diferente de zero é observado pelo toróide e portanto um sinal pode ser recebido.Invention Patent: "DATA TRANSMISSION IN OIL PIPELINE SYSTEMS". A first set of apparatus is arranged to transmit data from a point in a closed section of a well (1.3) to a remote location. The device can be used as a relay station (6) to increase operational depth. The signals are applied to and received from the string (1) at the relay station (6) and a selected length of the string (1) is provided with an insulating spacer feature (9) on either side of the relay station to ensure that the string ( 1) and the cladding (3) are effectively isolated for a minimum selected distance. This allows the potential differences to be applied to and detected from the string (1), thus enabling the transmission and reception of data. A second set of apparatus (figure 8) is arranged for transmitting an indoor unit (408) within a closed section of the well (401,403) to the immediate surrounding area outside the casing (403). The indoor unit (408) injects current into the string (401). A toroid (415) surrounding the casing (403) is provided to pick up signals. The spaced connections between the rope (401) and the sheath (403) are provided by conductive plugs (411). An inequality in the current flowing in the rope (401) and sheath (403) is generated, so that a non-zero flow is observed by the toroid and therefore a signal can be received.
