摘    要:煤层在地震勘探中属于薄层,其薄层厚度预测一直是公认的难题,传统的预测方法是利用钻孔资料的内插对比获得,精度很低。对频率域预测方法进行了研究与对比,并嫡制相应的频域定量预测方法的程序进行煤层厚度定量计算。该类方法将频率属性定量化,其计算有简单易行、精度高、煤厚分辨率高等特点。

关 键 词:薄层  钻孔标定  频率域  煤层厚度

Abstract:Coal seam belongs to thin layer in concept of seismic exploration, the prediction of thin bed thickness is one of the difficult problems generally acknowledged. And the traditional method of its thickness prediction is to use the interpolation method and contrast between the boreholes, whose precision is very low. In this paper, these methods are concluded and researched. Then quantitative prediction methods in frequency domain are adopted and relevant program is compiled to compute the coal seam thickness quantitatively by known borehole data. This type of methods can be used to quantify the frequency attributes, and the calculation is ease-to-use, of high precision, and has high resolving power in coal seam thickness.
Keywords:thin bed  borehole standardization  frequency domain  coal seam thickness
