FILTERING IMPROVING THE ACCURACY OF PREDICTED COAL SEAM THICKNESS

摘要: 道积分法反演煤层厚度,其计算的煤层厚度往往受到地震子波的类型和主频的影响。根据煤厚的分布范围,选择合适的滤波频带,对道积分剖面进行滤波处理可以提高煤厚的反演精度。

Abstract: It is possible to predict coal seam thickness with trace integration method, but the type and dominant frequency of wavelet have an effect on the calculated coal seam thickness. The accuracy of predicted coal seam thickness can be improved by choosing the proper filtering bandwidth in accordance with the distribution range of coal seam thickness and filtering the trace integration sections.
