摘要
煤炭地质找矿工作深度逐渐由浅部开展到深部,通过地震资料分析确定地质孔深度具有一定的难度。通过以往地震属性成果资料中岩石物性参数及进行研究分析,预测煤层埋深,结合钻探测井资料进行标定和验证。结合豫北某普查区的地震资料和已知钻孔,对区内煤层埋藏深度预测进行了应用分析,验证了该方法的可行性。
It is difficult to determine geological hole depth according to the seismic data as the coal geological prospecting work gradually was carried out from shallow to deep. The petrophysical parameters in the past results of seismic attribute data were used to predict the buried depth of coal seam,in combination with drilling logging data for calibration and validation. According to the seismic data of census area in north of Henan province,the authors analyzed the prediction of the known buried depth of coal seam,and the feasibility of the method was validated in practices.
