电缆遥测传输是测井系统传输数据的主要方式。针对测井电缆传输速率低、 带宽窄等瓶颈问题 ,提出应用

ADSL 宽带网络接入的离散多音频调制(DMT)技术进行电缆传输的调制和解调 ,从理论上对此技术进行了详细分析 ,并

通过计算机仿真试验 ,证明该方法对于提高电缆的频带利用率是可行的。-Cable telemetry transmit is a main way of data transmission in well logging systems. In this paper , due to a variety

of shortcoming of logging cable , such as low transmit speed and narrow bandwidth , a DMT technology with the

application of ADS L wide band is presented. This technology is analyzed theoretically in detail , and it has been proved

that this method is feasible in increasing the bandwidth using efficiency of the cable by compute emulation.
