摘要
Geological structure is complicated in the north yellow sea basin.In the reflection seismic data obtained from some areas,the deep reflection is unclear,leading to multiple solutions in seismic data interpretation.In this paper,the authors analyzed the difference and connection between travel time curves of the reflection wave and the refraction wave,made the most of the potential of seismic reflection data,used their refraction data,analyzed refractive characteristics of the basin,and calculated the velocity of the basement,to make up the weaknesses of the velocity analysis of the reflection data.The refractive wave velocity was used to infer geological attributes and divide seismic horizons.The results obtained improve the precision of the intermediate and deep horizon seismic data interpretation in the north yellow sea basin,and make the seismic data interpretation more reasonable.
