【摘要】 介绍了小波变换的定义及小波变换的性质，特别介绍了零通小波的理论及其如何在地震勘探资料处理中的应用。通过理论模型的计算及处理，得知用小波变换可以划分地层厚度为λ／６的顶底界面的反射复合波，使地震资料的分辨率大为提高。把这种方法应用于某地区的实际资料处理，达到了预期目的。更多还原

【Abstract】 The paper introduces the definition of wavelet transform and its properties.Especially the philosophy for zero-crossing wavelet and how it can be used in seismic prospecting are presented.According to the calculation of model,we can recognize the layer depth up to λ/6 from synthetic wave reflected from top and bottom interface with wavelet transform ,which greatly enhances the resolution of seismic digital processing.It is also applied to practical digital processing in some district and gets the anticipated result.更多还原
