Abstract

The NYS area of Qaidam Basin is characterized by well developed faults and fractures,and complex geological structure.Because of the poor imaging accuracy,the conventional stack imaging method is difficult to salty out the fine interpretation of structure an d fault.Aimed at the tectonic features of NYS area,the parameters of Kirchhof pre-stack migration velocity and migration aperture are optimized,which improves the pre-stack imaging quality and realize fine geological structure interpretation.
