选择使用观测钻孔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的异常特征,从中发现煤层与围岩的突出特征,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,对个别的煤层进行定位定论。
We choose to use logging logging data of 3 or more valid coalfield logging parameters to analyze and compare the anomalous characteristics of all the curves and find out the prominent features of the coal seam and surrounding rock so as to achieve the qualitative interpretation of the target layer. Thick interpretation focuses on the use of typical eigenvalues of apparent resistivity and gamma-gamma curve anomalies to determine the depth, thickness and structure of the coal seam, sometimes using morphological features, signatures, and contrasts of the physical property parameter curves for individual coal seams Positioning conclusion.
