| Abstract: | For production logging,a single-core cable telemetry system is used for the data transmission from the downhole to surface computers.To meet the needs of a great deal of data transmission for imaging logging and integrated logging,a novel high-speed single-core cable telemetry transmission scheme is presented based on orthogonal frequency division multiplexing(OFDM)technique.It overcomes the inherent detects of single-core cable logging and improves frequency band efficiency.The scheme is a more ideal modulation and demodulation scheme for the high-speed data transmission of production logging.It can provide a help for the development of practical logging data transmission system. |
| Keywords: | single-core cable data transmission OFDM |
