Variable-coefficient coal seam reflection elimination method and variable-coefficient coal seam reflection elimination device

The invention discloses a variable-coefficient coal seam reflection elimination method and device. The technical scheme disclosed by the invention fully considers that coal seams with different thicknesses can generate seismic reflection energy with different intensities, the strong reflection separation coefficient is constrained by using the coal seam thickness subjected to well drilling statistics, the larger the separation coefficient of a thicker coal seam area is, the more energy is removed, and the smaller the separation coefficient of a thinner coal seam area is, the less energy is removed, and the separation efficiency is improved. And the seismic data better conforming to the actual geological condition can be obtained. According to coal seam reflection elimination based on variable coefficients, coal seam reflection characteristics can be effectively identified and separated, reservoir effective reflection hidden under coal seam strong reflection is highlighted, and a data foundation is laid for hi
