| 摘 要： | 基于动态情形介质参数是频率的复函数,利用复小波变换处理地震勘探反射波数据,求出每时刻瞬时谱曲线,它刻划了该时刻所对应的地层介质性质．本文提供一种全新的由反射波数据绘制地下剖面图以取代反褶积的方法,提出用“三基色”方法来提取这条谱线的特征,合成彩色地下剖面图,并利用特制的小波软件对油田实际资料进行研究．

| Abstract: | A new method is proposed for drawring undergroud section, taking theplace of deconvolution method of reflected wave. Its physical basis is that allparameters of medium in moving situation are complex function of frequency. Theinstantaneous spectrum of reflected wave in seismic prospecting obtained by complexwavelet transform characterizes properties of itS corresponding medium level. The newmethod of "3 basic colors" is used to abstract features from these spectrums and drawsectional figure. Using our wavelet software and practical seismic data obtained fromoil field some figures are shown. |
