摘要
在深层油气勘探中,针对深层地震数据的特点,我们利用二维小波变换技术易于分离信号和噪声的特点,将其应用于东部深层地震资料的处理中,对面波的消除取得了令人满意的结果,大大提高了深层地震资料的信噪比.
Upon the characteristics of deep seismic data, we use the characteristics of two-dimensional (2-D) wavelet transforms that is apt to separate noise and signal, and then apply it to deep oil and gas exploration. Some satisfactory results are obtained in surface wave eliminations, and it greatly improves SNR of deep seismic data.
