摘　　要：本方法根据薄煤层厚度与其振幅基本呈线性关系的原理,利用三维地震资料解释系统提取煤层反射波振幅参数,对生成的彩色平面振幅图进行分析,进而圈定出煤层变薄带的范围。并以实例说明了该技术方法在解释煤层变薄带方面的应用效果。Based on the principle that thin coal-seam thickness is basically in linear relationship with its amplitude, this paper, by using 3D seismic data interpretation system, extracted coal seam reflection wave amplitude slice to analyse the colour diagram of planar amplitude generated and delimit the coal seam thinning zone. An example was used to show the applicability of the method to interpretation of the thinning zone.
