摘　　要：根据岩性油气藏的特点,以鄂尔多斯盆地大牛地气田为例,提出了利用基于小波变换的时频分析方法进行岩性油气藏储层预测的思路,给出了利用小波变换进行时频分析的计算过程以及利用基于小波变换的谱分解技术进行储层预测的关键步骤。最后,用基于小波变换的谱分解技术对鄂尔多斯盆地大牛地工区的地震资料进行了频谱成像。This paper proposed to predict lithologic reservoirs with wavelet transform based time-frequency analysis.We discussed the procedure of time-frequency analysis based on wavelet transform,and the key steps of reservoir prediction with spectral decomposition.The proposed methods were demonstrated with data from Daniudi gas field,Ordos Basin.
