Seismic exploration is a system engineering based on seismic acquisition technology.The transformation of seismic acquisition technology is not only the starting point of equipment upgrading and theoretical innovation,but also the source for solving technical problems in seismic processing and interpretation.The development history of seismic exploration reflects the driving role of equipment capacity improvement,geological study demand,and progress of wave field theory.Among them,seismic acquisition technology is full of vitality and faces great challenges.Given the rapid development of big data and artificial intelligence,the reflection wave seismic acquisition technology,characterized by CMP stack and using sparse,regular,and single observation system,is increasingly unadaptable for imaging of small-scale,non-layered and non-uniform media.Meanwhile,the application of scattered wave seismic acquisition technology characterized by CMP discretization and using stochastic,ergological,and multi-observation system is imperative,so as to meet the imaging requirements of small-scale,non-layered,and subtle targets.Similarly,as the theoretical basis of scattered wave seismic acquisition technology,the study on stochastic theory and probability wave theory is gradually emphasized.
