Abstract

In order to clarify the seismic sedimentology interpretation method under coal seam interference, time-frequency analysis technology was used to analyze the seismic reflection frequency of the coal seam. Combined with seismic filtering, the seismic interference of the coal seam is suppressed through the sedimentological interpretation of stratigraphic slices with different dominant frequencies. The spatial distribution characteristics of the sedimentary system are determined by comprehensive mixed display technology. The results show that the delta plain subfacies are developed, which are composed of four distributary channels, crevasse splays, and swamps in the near north-south direction, and a large-scale channel migration zone is formed in the southwest.
