Abstract：As an effective method to find out the deep geological structure and tectonic features,deep reflection seismic detection can provide detailed geologi-cal data for the overall planning and construction of Xiong'an New Area and 10000-meter "Transparent Xiong'an New Area" basic platform. Therefore,deep reflection seismic is applied to the geological survey of this area and its surroundings. Meanwhile,research on high-precision imaging technology of deep reflection seismic is carried out. Given the long length,wide span,imbalanced energy,weak signals at depth,and complex and variable noise of the deep reflection seismic profile in Xiong'an New Area and its periphery,a targeted high-precision imaging process of deep reflection seismic is designed and formulated. The key applicable technologies are also selected to gradually extract effective signals of deep reflection seismic,which are related to stratum interfaces and tectonic features from the complex seismic wave field. The SNR and resolution of the final results are high,with rich geological information,distinct structural framework,and clear strata relationship extracted from the deep reflection seismic profile. The results can provide data support for stratigraphic identification and comprehensive geology (resource) evaluation in this area and can better serve the basic geological construction of Xiong'an New Area.
