Construction of Two-Dimensional Seismic Image or the Geological Environment by the Results Offset VSP

摘要

Technology offered by the authors obtain seismic images of the geological environment on the VSP results comes from the fact that the returning seismic energy is in the form of diffracted waves. Each recorded seismic track offset can be considered as the result of the interference summation of multiple diffracted waves formed of any real local inhomogeneities of the geological environment, or virtual diffractors, which can with some approximation to approximate the actually existing in the geological environment extensive seismic reflecting boundaries. To improve the quality and sustainability (stability), we obtain seismic images of the geological environment, the transfer of the selected amplitude of the observed slopes should be done not in one settlement point, and a group of such points, which are combined in the "vertical large bin - LB"
