摘要: 以数字信号处理的重采样原理为依据,利用重采样后的反射波同相轴时差梯度进行5m以下小断层落差的定量估算。通过理论模型的研究以及实际地震资料的处理,可知此方法具有对小断层反映灵敏,落差定量解释精度高的特点。Abstract: Using time difference gradient of reflective event after re-sampling during digital signal processing for seismic data,an estimation of drop height for small-scale faults(<5m) was conducted.Modeling and field seismic data processing indicated that this method could enhance the drop height interpretation for small-scale faults.
