Abstract This paper gives a brief review of the seismic technology development level in uranium exploration,and decribes the application status of seismic exploration technology for sandstone type uranium deposits in China from the aspects of collection,processing and interpretation based on the results of seismic exploration work in nuclear geological system in recent years.Through the comparative analysis of the development level of similar technologies in China and abroad,the authors have found out the gaps between China and countries abroad in this field.Here are some examples of China's shortcomings in this field:lack of studying seismic acquisition methods for sandstone type uranium deposits,relatively low precision of shallow seismic data processing and interpretation accuracy,backwardness in such aspects as the work of seismic attribute analysis of sandstone type uranium ore body,prestack inversion technology research,and target sand body modeling.Aiming at tackling these problems and considering characteristics of uranium mineralization,the authors put forward some countermeasures and suggestions for speeding up the development of seismic exploration technology of sandstone type uranium deposits in China,such as optimizing the acquisition surface,detailed demonstration and testing of the coverage,developing the seismic processing technology for ultra shallow (less than 100 m) sandstone type uranium deposits and weak information extraction technology of interlayer sand,research on the technology of shallow noise removal and high precision imaging,study of the physical modeling of uranium and non-uranium bearing sandstone and analysis of the seismic attributes of the target sand body.
