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.
