摘　　要：应用正演模拟技术,在时间域和频率域对薄互层地质模型的反射特征进行深入分析。利用实际资料建立地层模型,分析砂岩、泥岩和盐岩的反射特征,并用谱分解法预测盐岩的分布范围及厚度,应用效果较好。By means of forward modeling technique,we meticulously analyzed the seismic reflection of thin interbeds in time and frequency domain respectively. We made use of actual data building strata models,analyzed the reflection characteristics of sand,shale and salt,and predicted the distribution range and thickness of salt by spectral decompostion method. These techniques have yielded satisfactory application in Dongpu depression.
