摘要
分析各个钻孔测井资料间的内在联系,可以推断煤层和地层,研究煤层在平面上的变化规律,推断钻孔间的地质构造。文章选择常规数字测井中采用的三侧向电祖率(LL3)、人工伽玛(GGL)、自然伽玛(GR)3种曲线,进行大河宣威组11层主采煤层的对比研究,结果表明,利用测井曲线的异常幅度、形态及特殊标志进行煤层对比效果显著。
By analyzing the inner link of logging information, the coal seam and stratum, flat change role of coal seams and the geological structure of each borehole can be deduced.In this paper, coal seams in the main mining area of Xuanwei Formation of Dahe Coal Mine are compared by using conventional digital logging in three lateral power ratio （LL3）, artificial gamma（ GGL）and gamma （ GR ）, three kinds of curve.The results show that it has outstanding effect to compare coal seams by anomaly amplitude ,form and special mark of logging curve.
