利用小波变换井震联合提高地震资料分辨率

通过测井资料和地震资料联合处理，实现互补，从声波测井或密度测井资料中，提取高频及低频信息，提高地震记录的主频，展宽地震资料的频带，进而达到提高地震资料分辨率的目的，利用小波变换技术，对地震记录作多尺度分解，适当地选择小波函数的参数，可以改变地震资料的频率成分，使之接近谱白化，本方法的特点是参数容易选择，运算速度快，处理之后，地震剖面的分辨率明显提高。

Heighten Resolution of Seismic Informations Through Application of Wavelet Transform and Combine of Logging and Seismic

Through combine processing of logging and seismic informations, make it supplement each other. From materials of acoustic log and density log, pick up informations of high frequency and low frequency, heighten main frequency of seismic record, widen frequency band of seismic informations, and further to realize purpose that heighten resolution of seismic informations. Apply technique of wavelet transform, multiscale decompose seismic record, and suitable selection on parameter of wavelet function, may be changed the frequency composition of seismic informations, and make it near to whiten. Properties of this method: parameters selection easy, counting speed quickly, and after processing, resolution heighten clearly.
