基于测井数据判别分析法识别构造煤的应用

Application of Identifying Tectonic Coal with Discriminant Analysis Method Based on Logging Data

针对构造煤与原生结构煤分界处的煤体类型不易识别的问题,运用判别分析法,选取构造煤、原生结构煤的测井数据为样本。首先对测井数据进行标准化,再优选测井曲线。通过数据处理来建立分类标准,对待识别的煤层测井采样段进行逐一判别、归类。将该方法运用于山西寺河井田进行构造煤识别。以识别出的各钻孔构造煤数据为基础,利用线性插值法得出该区构造煤分布发育图。经比较与钻孔、巷道揭露的情况基本吻合,验证了该方法的正确性,同时提高了识别构造煤的精度。

In view of the problem of separating tectonic coal and primary coal from the parting,we used the discriminant analysis method,and selected the logging data of tectonic coal and primary coal as samples. First of all,we standardized the logging data,and then optimum the well logs. For distinguishing the coal and identify the category,we choosed curves and processed data to establish the classification standard. We has applied this method to Sihe mine in Shanxi Provincel. On basis of tectonic coal distinguished,the linear interpolation method was selected to draw the graph of deformed coa,which is agreement with the actual data exposed by drillings and roads,so this method was correct,and the the accuracy of identifying tectonic coal had a enhancement.
