摘　　要：在现有资料基础上进一步提高地震资料分辨率,预测薄储层的空间展布规律是一项具有重要意义的工作,本文采用基于傅里叶算法连续小波变换分析技术进行地震信号的分解和重构,通过正演和准噶尔盆地西北缘实际地震资料分析表明本文给出的方法在保持地震资料信噪比的基础上能有效提高地震资料分辨率,突出薄互层的内部细节,其结果可用于精细刻画薄互层型地层的空间展布,有利于薄储层预测.Improving seismic data resolution and predicting spatial distributions of thin bed have important significance to Petroleum Exploration.The aim of the article is to improve seismic data resolution which contain important geological Information by using an FFT algorithm to compute the CWT and reconstructs seismic data.Through analyzing the model and actual data,it was indicated that the method effectively improve the resolution in the case of keeping the SNR of seismic data.The detail of thin bed can be more clearly observed.Its results will be helpful to thin interbed distribution delineation and reservoir prediction.
