A New Method of Constructing Seismic Images of Geological Media From Seismic Data of the CDP 2d

Abstract

The theory of a new method of obtaining profile seismic images of the geological medium in the form of dynamic deep or time sections is developed. The proposed new approach to obtaining seismic images of the geological environment is free from the above-mentioned drawback. It is shown that an adequate understanding of the environment can be obtained if in the process of building the images provided by shifting each of the amplitude observed on seismograms of reflected waves in images of the environment that corresponds to areas of the actual formation of these waves. To do this, you must first obtain information about the distribution of the profile and depth in the context of the values of the effective speed and angles of incidence of the reflecting boundaries. On this basis, a method for obtaining more objective seismic images of the geological environment from 2D seismic data has been developed and tested. The proposed technology for obtaining seismic images of the medium is a natural generalization of the technology of summation by CDP but allows you to directly obtain migrated seismic images of the medium.
