Review of Double-Focusing Imaging Technology in Seismic Exploration

Abstract

This paper systematically summarizes the research progress of double-focusing imaging methods in seismic exploration. As an observation system evaluation method based on wave theory, the double-focusing imaging method can directly reflect the prestack migration imaging effect and provide a scientific basis for the design of observation systems in seismic exploration. It systematically sorts out the theoretical basis, development history, algorithm improvement, application examples and future trends of the double-focusing imaging method, focuses on expounding the evolution process of the double-focusing method from homogeneous media to complex media and from sparse acquisition to "two-wide and one-high" acquisition, and analyzes the influence law of key parameters of the observation system on imaging quality, providing theoretical guidance and practical reference for the design of observation systems in seismic exploration.
