摘要
选择使用观测钻孔内3种(含3种)以上有效的煤田测井物性参数,分析和对比所有曲线表现的异常特征,从中发现煤层与围岩的突出特性,达到对目的层的定性解释,而定厚解释是重点利用视电阻率和γ-γ曲线异常的典型特征值,确定煤层的深度、厚度和结构,有时还利用诸物性参数曲线异常的形态特征、标志层、对比方法,对个别煤层进行定位定论。
Three or more than three effective coalfield logging physical character parameters from the observational drill holes were used to analyze and compare anomalous characteristics of all curves for the purpose of detecting prominent features of coal seams and wall rocks and making qualitative interpretation of the bed of interest. The thickness-determining interpretation utilizes emphatically typical characteristic values of apparent resistivity and artificial radioactive curve anomalies to determine the depth, thickness and structure of the coal seam. The morphological feature, index horizon and correction method of the curve anomalies of various physical character parameters are sometimes also used to study individual coal seams.
