测井曲线对比在煤田地质勘探中的应用

Application of Logging Curve Correlation in Coalfield Geological Exploration

在煤田地质勘探中,利用测井曲线进行地层对比是综合解释的重要方法之一,也是测井资料地质解释的基本工作之一。测井物性特征对比法是煤层对比的主要方法。在构造复杂、煤层不稳定、标志层不明显、无岩芯钻进或岩芯采取率低的情况下,测井物性特征对比法的作用更为突出。测井曲线对比更是研究煤层和地质构造的必不可少的重要方法。

In the coalfield geological exploration, the use of logging curves for stratigraphic correlation is one of the important methods of comprehensive interpretation, also is one of the basic work of geological interpretation of log-ging data. Logging characteristics of the contrast method is the main method of coal seam contrast. In the case of com-plicated structure, unstable coal seam, no obvious mark layer, no core drilling or low core, the logging characteristics of the contrast method is more prominent. Logging curve correlation is an important method to study coal seam and geological structure.
