目前正在使用一种提高地震解释精度的新方法。这种新方法就是数字偏移技术。它能对地震讯号进行偏移校正,结果以时间或深度来表示。这种新的处理方法有可能直接从地震资料对时间剖面作偏移校正,而不必首先对比选择同相轴。并且所有时间剖面上的重要特性都能保留在作过偏移校正的剖面上。这些特性包括子波特征,频带宽度,清晰度以及讯噪比。 A new method of improving the accuracy of seismic interpretation is currently being used. This new method is digital offset technology. It can offset the seismic signal and the result is expressed in time or depth. This new approach makes it possible to offset the time profile directly from the seismic data without having to first select the events for comparison. And all the important features on the time profile can be preserved in the offset-corrected profile. These features include wavelet features, bandwidth, sharpness, and signal-to-noise ratio.
