The design and optimization of geometry for complex structures,especially special structural areas such as salt hills,is currently one of the challenges faced by seismic exploration.In order to meet the require-ments of seismic imaging accuracy and resolution in complex structural areas,wide azimuth and high-density seis-mic exploration acquisition technology continues to develop.However,pursuing high density in directions with already high imaging accuracy alone can lead to resource waste.Focusing on the problem of local target seismic imaging of underground complex structure,with the help of angle domain imaging method,the complex structur-al target is decomposed into different local targets according to the imaging point,and according to the require-ments of local targets for seismic survey parameters,an optimizing method for offset of seismic survey design for local targets is proposed,and the most effective receiving area at the surface can be obtained according to the principle of 85％energy convergence,so it can provide technical support for all-target seismic exploration and seismic survey parameters optimizing.
