由于地震勘探分辨率不高，使得每一个地震反射波都是由一组薄互层所产生的地震波相互叠加的结果，利用这样的地震资料进行常规的薄层、薄互层解释是十分困难的。本文对薄层、薄互层地震反射在时间域和频率域进行了正演模拟研究，制作了砂岩楔状体及等厚互层砂岩厚度与振幅、频率关系曲线，揭示了振幅、频率、波形与砂岩发育程度及互层结构之间的关系。最后利用振幅、频率和波形对汪家屯气田北块扶杨油层砂体进行了综合预测，提高了预测精度。
Due to the low resolution of seismic exploration, each seismic reflection wave is caused by the superimposition of seismic waves generated by a set of thin interbeds. It is very difficult to use conventional seismic data to interpret thin and thin interbeds . In this paper, the seismic reflection of thin and thin interbed is studied in the time domain and frequency domain. The relationship between thickness, amplitude and frequency of sandstone wedges and isophoric interbedded sandstones is established. The amplitude, frequency, The relationship between sandstone development and interlaminar structure. Finally, the amplitude, frequency and waveform are used to comprehensively predict the sand body of Fuyang reservoir in the north of the Wangjiatun gas field, which improves the prediction accuracy.
