Abstract

Firstly, from the point of view of the frequency domain Helmholtz equation, a detailed description of the frequency domain modeling process and frequency domain blended seismic acquisition forward process were given. By solving the Helmholtz equation, reverse-time migration method in frequency domain is derived. Reverse time migration method based on frequency domain, the frequency domain least-squares reverse-time migration technology. Based on the Marmousi model, the typical representative, through the method of mixing the offset frequency domain and achieved good results. Comparative analysis of the factors of the frequency domain least-squares reverse-time migration effect and advantages and disadvantages.
