陶二煤矿无烟煤与天然焦在测井曲线反映特征

Tao'er Mine Anthracite and Natural Coke Logging Curve Reflection Characteristic

由于陶二煤矿扩大区受煤系地层隐伏的巨厚层岩浆岩体影响,煤层变质为无烟煤,局部变质为天然焦,通过对本区测井物性参数曲线视电阻率、散射伽玛、自然伽玛物性特征的分析、对比,找出了两者之间明显区分物性特征,并把3个参数曲线结合起来,可以直接有效的利用测井参数曲线解释、划分无烟煤与天然焦。

Due to Tao＇er Mine expanding area influenced by coal measures strata concealed thick layer magmatic rock, coal seam went bad for anthracite, part went for natural coke, based on the apparent resistivity logging curve of physical parameters in this area, physical characteristics of scattering gamma, natural gamma analysis, comparison, the clear distinctions between physical characteristics were found out, combined with parameters curve, which directly used the curve interpretation, logging parameters and effectively differentiated anthracite coal and natural coke.
