英文摘要Signal-to-noise ratio (SNR) estimation of seismic data is important for the following data processing and interpretation. Almost all of the current algorithms for SNR estimation need to estimate the effective signals in the noisy data during calculations. However, there are always bias errors exiting in these SNR estimation results because the effective signals in the noisy data cannot be estimated accurately. In this paper, we propose a deep convolutional neural network architecture to estimate local SNR of the seismic data. Firstly, the network learns a feature mapping from a normalized noisy data patch to its SNR value by training and optimizing parameters. Then, the network can predict the SNR when it is fed in a seismic data patch, without the need of effective signals. Synthetic data and real data tests show the effectiveness and efficiency of our method to estimate the SNR and evaluate the quality of seismic data.
