| 摘 要： | 红四井田含煤地层为二叠系下统山西组和石炭二叠系太原组,编号煤层12层,通过对该区视电阻率（三侧向电阻率曲线）、自然伽马曲线、伽马曲线的形态及组合规律的分析,并综合对比了该井田的煤岩层可知,5-1煤层上部中粗砂岩砂体、9-1煤层顶板的石灰岩在测井曲线上的特殊特征可分别作为5煤层和9煤层的主要判别依据,同时5煤层至8煤层的组合特征在本区也是唯一的.红四井田测井曲线的实例对比表明,在该井田利用测井曲线可有效地进行煤岩层变化规律的对比研究及层位划分.

| Abstract: | Coal-bearing strata in Hongsi minefield is early Permian Shanxi Formation and the Carboniferous Taiyuan group,numbered 12 coal seams.In the area,through the analysis of resistivity（three side resistivity curve）,shapes of natural gamma curve,gamma curve shape and compositive rule,and comprehensive contrast of coal rock stratum,special characteristic in log curve of medium-coarse sand body at upper of 5-1 coal seam and limestone in 9-1 coal roof can be main criterion for 5 and 9 coal seam.And 5 to 8 coal seam has a unique combination features in this area.The logs in Hongsi minefield show that use logs can be effectively research variation of coal seam and strata division. |
