测井曲线在潘一矿13-1煤层识别构造煤中的应用

Application of Logs in Identification of Tectonically Deformed Coal for Coal Seam No. 13- 1 in Panyi Coal Mine

为预测未揭露区煤体结构,根据钻孔测井曲线信息,结合视电阻率电位曲线与伽马伽马曲线对煤层内不同结构分层物性差异所反映的形态特征,通过对煤层内部的各分层之间的比较、煤层与邻近钻孔中同一煤层的比较和煤层与钻孔内的上、下煤层之间进行比较绘制出煤层结构柱状图。又以矿井煤层底板等高线图作为底图绘制构造煤平面分布图,判识煤层内部的构造煤分布。

In order to predict coal seam structure in undisclosed area , based on borehole logs information , com-bined with morphological characteristics reflected by physical differences between different hierarchical structures with potential curve of apparent resistivity and gamma gamma curves , on the basis of comparison between layers inside the coal seam , and comparison between the coal seam with the same coal seam in boreholes neighboring to itself, and comparison between the coal seam and coal seams above and below it in boreholes , a histogram of coal seam structure was drawn .Based on coal seam floor contour map , the plane map of tectonic coal distribution was drawn to identify distribution of tectonically deformed Coal inside the coal seam .
