摘要
Based on the complicated seismic data from huge-thick sub-salt carbonate rocks in Pre-Caspian basin,this paper analyzes the formation mechanism of sub-salt pseudo-faults and pseudo-structures and presents related correction method through forward modeling and field cases,integrated with vertical seismic profile(VSP) and salt bed velocity analysis.And better results are obtained for refined interpretation of seismic data from the central block in this basin.
