钻孔约束频域定量预测煤厚方法研究与应用

Research and application of seam thickness prediction method with borehole restrained frequency area quantified

煤层在地震勘探中属于薄层,其厚度预测的传统方法是利用钻孔资料的内插对比获得,精度很低。实际生产中,人们又研究了多种办法。对这些办法进行了归纳,并采用钻孔约束频域定量预测法(谱矩法)来编制相应的程序进行煤层厚度定量预测。

Coal seam is a thin stratum in seismic exploration. The traditional method to predict the thickness was to use interpolation and contrast of the borehole information. The precision of the prediction was lower. In the actual production, people developed many methods to predict the thickness. Those methods were concluded. The borehole restrained frequency area quantified was applied to prepare a related program for the quantitative prediction of seam thickness.
