    • A reliable downhole acoustic telemetry system with increased data rate is disclosed. In one embodiment, the telemetry system includes a receiver having an envelope-detection demodulator and a multipulse-block distance detector that compares a baseband envelope signal to stored waveforms and indicates for each symbol interval the multipulse block having the waveform closest to the baseband envelope signal. The receiver may also include a timing recovery module that models the baseband envelope signal for the detected multipulse blocks and determines a distance for early-sampling and late-sampling of the baseband envelope signal. The timing recovery module then provides a sampling clock that minimizes the average difference between the early- and late-sampling distances. The telemetry system may further include a transmitter having an encoder and a modulator. The encoder converts a data signal into a sequence of multipulse blocks having a settling interval between the blocks. The modulator modulates the multipulse block sequence with a carrier frequency to produce an amplitude modulated signal. The telemetry system may have the transmitter and receiver coupled to a tubing string by an acoustic signal generator and an acoustic transducer, respectively. The acoustic signal generator converts the amplitude modulated signal into acoustic waves that propagate along the tubing string to the acoustic transducer, which then converts the acoustic waves into a receive signal. The system and method disclosed may advantageously provide a robust, low-power telemetry system that communicates telemetry along a tubing string at a rate that is at least an order of magnitude greater than existing acoustic telemetry methods.
    • 公开了一种具有增加的数据速率的可靠的井下声学遥测系统。 在一个实施例中,遥测系统包括具有包络检测解调器和多脉冲块距离检测器的接收机,其将基带包络信号与存储的波形进行比较,并且针对每个符号间隔指示具有最接近基带包络信号的波形的多脉冲块 。 接收机还可以包括定时恢复模块,其对所检测到的多脉冲块进行基带包络信号的建模,并确定基带包络信号的早期采样和后采样的距离。 定时恢复模块然后提供采样时钟,其使得早期和晚期采样距离之间的平均差异最小化。 遥测系统还可以包括具有编码器和调制器的发射机。 编码器将数据信号转换为在块之间具有建立间隔的多脉冲块序列。 调制器用载波频率调制多脉冲块序列以产生幅度调制信号。 遥测系统可以分别通过声信号发生器和声换能器将发射器和接收器耦合到油管柱。 声信号发生器将幅度调制信号转换成沿着管柱传播到声换能器的声波,声换能器然后将声波转换成接收信号。 所公开的系统和方法可以有利地提供鲁棒的低功率遥测系统,其以比现有的声学遥测方法大至少一个数量级的速率沿油管柱传送遥测。
