摘要
以漳县盐矿区为例,介绍了用测井方法确定岩矿层的优势所在;依据岩系地层的电性、放射性及它们之间的相互关系,用二元回归方法得出了矿区的理论方程;列举了用经验方程进行盐矿品位解释的应用效果。检验结果说明,用回归分析方法对测井资料作定性、定量解释是可行的;对于满足相关条件的岩盐矿层,利用该法可以获得较为理想的地质结果,对盐田的评价有着现实的指导意义。
Exemplified by the Zhangxian salt district, this paper points out the advantages of applying the logging method to locating the rock and mineral bed. According to the electric character and radioactivity of the strata as well as their relationship, the binary regression method was used to obtain the theoretical equation for the salt mine district. The result of applying the empirical equation to salt mine grade interpretation is also given. Tests show that the application of the regression method to qualitative and quantitative interpretation is feasible. For the rock salt bed which can meet the related conditions, the utilization of this method can yield fairly ideal geological result, which has practical guiding significance in salt field evaluation.
