Deep seismic data from the Gaoshiti-Moxi area had low quality and accuracy for predicting gas reservoirs. By combining seismic and well data, researchers identified and suppressed interference from multiple signals in deep layers. They improved imaging quality and reservoir prediction accuracy using techniques like velocity modeling and amplitude control. By integrating different types of seismic data, they enhanced fault identification and reservoir mapping. This approach helps analyze seismic data more deeply, develop better processing techniques, and improve reservoir prediction accuracy for future exploration and development of deep reservoirs.
