摘      要：In areas with a low signal-to-noise ratio of seismic data,the continuity of the seismic reflection waves in the exploration target layer is very poor,which will reduce the imaging accuracy and make it impossible to solve certain geological *** article suggests an approach to address the issue of seismic acquisition by optimizing excitation *** involves conducting a detailed investigation of the surface structure,enhancing the observation system,increasing the coverage appropriately,and transitioning from combined-well excitation to single-well ***,the use of technical tools like qualitative evaluation of the observation system and forward modeling are employed to determine the final optimized seismic acquisition *** effectiveness of this approach is evident from the seismic profile obtained in an exploration area in Inner Mongolia.
