采用测井曲线对比云南富源矿区龙潭组主采煤层

Contrast of Main Coal Seam of Longtan Formation in Fuyuan District of Yunnan Province by Geological Logging Carve

选择常规数字测井中采用的视电阻率、人工放射性、自然放射性3种测井曲线,对云南富源矿区龙潭组7,9,15,16,17,23及24等七层煤层进行对比,其方法是:利用测井曲线连续性中的突变性和突变组合性规律,对它们进行对比,其效果显著,为利用地质模型难以精确对比的龙潭组的七层主要煤层,开辟了对比的新思路,对该区中、深部煤层开发有着重大的指导意义。

Make a contrast of seven, nine,fifteen, sixteen, seventeen, twenty- three and twenty- four coal seams in Longtan formation in Fuyuan District of Yunnan Province by electricity - respectrity rate, reflex - radioactive and natural radioactive logging cure. Its method is following： utilizing the coal contrast of disastrous variation and its compound law. The effect is obvious. The method resolved the difficulty of accuracy contrast. The research has a guiding significance for the district development in middle and deep coal - bed.
