摘　　要：高分辨率三维地震勘探能够获得地下空间三维数据体的大量地质信息,为工作区煤层厚度的确定提供依据。通过常用的三种方法谱:矩法、振幅谱平方比法、地震振幅谱和子波振幅谱比法,提取三维地震数据体中地震属性,编制相应的软件程序,对煤层厚度进行预测。研究对比了这三种算法的预测效果,为煤田煤层厚度的预测提供了可靠的参考依据。High resolution 3D seismic exploration is widely used in the coalfield to get 3D data volume, which contains a wealth of geological information for extracting coaI thickness information from seismic data. This paper applies three method to extract seismic attributes from 3D seismic data, including the methods of spectral moment , amplitude spectrum square and seismic spectrum ratio and wavelet amplitude. The relevant software was programmed and coal thickness was predicted. The compare predictive results of the three methods in this paper can provide credible reference for coal thickness prediction in coalfield.
