Methodology Research on Refraction Stack Imaging of Refractive Seismic Recording

Multi‐fold refractive seismic exploration is such a method that is generally used to trace the geological structural interfaces when the reflected seismic section is not good or used to trace the base structural configuration and to study the base interface. This paper will discuss the theory and me...

Description
Summary:Multi‐fold refractive seismic exploration is such a method that is generally used to trace the geological structural interfaces when the reflected seismic section is not good or used to trace the base structural configuration and to study the base interface. This paper will discuss the theory and method of imaging underground refractors with the refractied seismic waves in the refractied seismic data, based on the refraction theory. The method was called common depth refraction segments stack imaging method. The velocity analysis steps and NMO processing of the refractive wave by use of the theory and the method will also be given. A better imaging method, the common depth refractive point stack imaging method, will be proposed in the paper. Finally, the exactness and the practicality of the given methods will be verifired by processing model example and real data.
