Abstract:

Although prestack depth migration of shot records can make a high-quality image,it needs too much computation for wavefield extrapolation and lowers the efficiency of the computation.Prestack depth migration of areal shot records and controlled illumination can get high-quality images by source wavefield controlling and highly efficient areal shot records migration. How to calculate the synthesis operator is the key problem of controlled illumination prestack depth migration. In this paper the inverse time focusing operator is synthesized based on the travel time calculation method of finite difference approach, and with this synthesis operator the authors calculate the focusing point controlled llumination prestack depth migration using Fourier finite difference.The test results of Marmousi model show its effectiveness and the great advantage of improving computational efficiency.

Key words: multi-factor controlling, four-factor entrapping, key-factor enrichment, stratigraphic-lithologic reservoirs, Erlian Basin
