摘　　要：对淮北某矿区72与82煤层共计65个钻孔测井资料进行统计研究发现:密度与自然伽马曲线幅值的异常可以判断煤层赋存,视电阻率与自然电位的曲线幅值异常结合可以判断煤层结构,综合视电阻率、密度与自然伽马曲线的幅值异常可以判断煤层夹矸与否。基于此,提出一种以视电阻率、自然伽马、密度与自然电位测井曲线的组合特征综合判断煤层赋存、结构与夹矸的方法。The sixty-five boreholes logging data studied about 72 and 82 coal seam in a mine of Huaibei,the results showed that the anomalies of density and natural gamma curve amplitude could be used to judge the coal seam occurrence,and the anomalies combination of apparent resistivity and natural potential curve could be adopted to determine the coal seam structure.By synthesizing the anomalies of apparent resistivity,density and natural gamma curve amplitude,it was determined whether the coal seam contained gangue or not.Based on this,the method was proposed that the coal seam occurrence,coal seam structure and dirt band was judged by the combination characteristics of using apparent resistivity,natural gamma,density and natural potential logging curve.
