There is great potential for resource exploration from Jurassic to Cretaceous in the Hashan area of Junggar Basin,but the existing 3D seismic data acquisition is based on the design of the deep layer,and the observation system,excitation,reception,and other parameters have not considered the shallow imaging requirements.Re-conducting 3D high-density seismic acquisition for shallow geological targets significantly improves shallow imaging effects and makes new exploration breakthroughs.There are significant differences between shallow and deep seismic acquisition designs.Based on the particularity of shallow earthquakes,this paper researches the design of observation systems and excitation parameters,forming a shallow 3D high-density acquisition design technology.The processing results of actual data show that this technology can significantly improve the quality of shallow seismic imaging compared with old data,and it is of reference value for similar areas.
