    • A precise downhole clock that compensates for drift includes a prescaler configured to receive electrical pulses from an oscillator. The prescaler is configured to output a series of clock pulses. The prescaler outputs each clock pulse after counting a preloaded number of electrical pulses from the oscillator. The prescaler is operably connected to a compensator module for adjusting the number loaded into the prescaler. By adjusting the number that is loaded into the prescaler, the timing may be advanced or retarded to more accurately synchronize the clock pulses with a reference time source. The compensator module is controlled by a counter-based trigger module configured to trigger the compensator module to load a value into the prescaler. Finally, a time-base logic module is configured to calculate the drift of the downhole clock by comparing the time of the downhole clock with a reference time source.
    • 补偿漂移的精确井下时钟包括配置为从振荡器接收电脉冲的预分频器。 预分频器配置为输出一系列时钟脉冲。 在从振荡器计数预加载数量的电脉冲之后,预分频器输出每个时钟脉冲。 预分频器可操作地连接到补偿器模块,用于调节加载到预分频器中的数量。 通过调整加载到预分频器中的数字,定时可以提前或延迟,以更准确地将时钟脉冲与参考时间源同步。 补偿器模块由基于计数器的触发模块控制,配置为触发补偿器模块将值加载到预分频器中。 最后,时基逻辑模块被配置为通过将井下时钟与参考时间源进行比较来计算井下时钟的漂移。
