摘　　要：准噶尔盆地哈山地区侏罗系到白垩系具有较大资源勘探潜力,但现有三维地震资料采集均为基于深层进行的设计,观测系统、激发、接收等参数均未考虑浅层成像需求,针对浅层地质目标重新进行三维高密度地震采集,对于提高浅层成像效果,取得新的勘探突破具有重要意义。浅层地震与深层地震采集设计具有较大差异,基于浅层地震的特殊性,从观测系统、激发参数设计方面开展攻关,形成了浅层三维高密度采集设计技术,实际资料的处理结果表明,与老资料相比该技术能明显提高浅层地震成像质量,对于类似地区具有参考价值。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.
