Method for predicting coal seam thickness based on waveform classification seismic facies technology

The invention discloses a method for predicting coal seam thickness based on a waveform classification seismic facies technology. The method is suitable for prediction and interpretation before the disclosure of coal seam thickness. According to the method of the invention, on the basis of the drilling constrained waveform classification seismic facies technology, borehole-side seismic trace waveforms are extracted so as to be adopted as samples for seismic facies identification training; mapping relationships between coal seam thickness and seismic facies is established; the seismic facies ofa work area is identified based on a neural network; and seismic facies information is transformed into coal seam thickness information for guiding the prediction of coal seam thickness. With the above method adopted, the prediction and interpretation of a regional identical-coal seam thickness interval can be realized. 本发明公开了种基于波形分类地震相技术预测煤层厚度的方法，适用于煤层厚度未揭示前的预测与解释；本发明利用钻孔约束下的波形分类地震相技术，通过提取井旁地震道波形作为样本进行地震相识别训练，并建立煤层厚度与地震
