Abstract

Seismic phase analysis and stratigraphic interpretation are important topics in geophysical research and have significant implications for

geological structure interpretation and oil and gas exploration. This paper proposes a deep learning-based method for seismic phase analysis and stratigraphic interpretation, which combines convolutional neural networks and recurrent neural networks to automatically extract features from seismic data and interpret stratigraphic information. First, the time series features of seismic data are extracted. Second, convolutional neural networks are used for feature extraction to obtain abstract high-level feature representations. Then, the recurrent neural network is used for sequence modeling of features to further improve accuracy and robustness. Through tests on public datasets, the effectiveness of this method has been validated, and compared with traditional methods, this approach can more accurately identify seismic phases and improve the precision and efficiency of stratigraphic interpretation.

Seismic phase analysis is a critical component of seismic data processing, which involves identifying different seismic phases from recorded data to understand the geological structure of the subsurface.

However, this task can be challenging due to the complexity of the data and the presence of noise and other factors that may interfere with the signals. To address these challenges, researchers have explored various methods of analyzing seismic phases, including traditional techniques such as manual interpretation and hand-crafted feature extraction, as well as more advanced machine learning approaches.

Recently, deep learning techniques, such as convolutional neural networks (CNNs) and recurrent neural networks (RNNs), have shown promise for improving the accuracy and efficiency of seismic phase analysis. CNNs are commonly used for image recognition, but they can also be applied to the analysis of time-series data such as seismic signals. By using a series of convolutional layers to automatically learn

features from the data, CNNs can effectively identify different seismic phases and improve the accuracy of seismic interpretation.

RNNs, on the other hand, are specialized for the analysis of sequential data, making them well-suited

for sequence modeling in seismic analysis. By

analyzing the temporal relationships among different features, RNNs can improve the accuracy of seismic phase identification and enable more precise
