Zusammenfassung:The invention relates to the field of oil-gas exploration, in particular to a seismic observation system design method based on an energy loss minimization target. Aiming at the situation that underlying rock energy fluid or energy density is sharply reduced due to the fact that seismic wave energy is violently absorbed and attenuated by a high-loss geologic body, an energy low-loss observation system design technology with the purpose of energy loss minimization is provided. Illumination and energy density for focusing to a mountain-front in-situ system are enhanced. Compared with seismic wave excitation receiving on the pushing and covering body, the scheme has the advantages that the propagation path length of seismic rays in the pushing and covering body with high propagation loss is greatly reduced, the energy loss in seismic wave propagation is reduced, and compared with a conventional enhanced observation scheme of adding encrypted shot points on the pushing and covering body, the drilling construction
