用自然伽马测井资料解释煤层镓含量初探

PRELIMINARY APPROACH INTERPRETING CONTENT OF Ga IN COAL WITH NATURAL GAMMA LOGGING DATA

    摘要
  • 摘要: 根据煤层中粘土矿物吸附放射性元素及Ga、Al元素置换;煤层Ga含量随灰分增高而增高等原理,利用自然伽马测井资料,可对煤层中的Ga含量进行计算。为综合利用高灰分煤和高碳炭质泥岩及含粘土较高的夹石提供了评价资料。

     

    Abstract: Based on clay ore adsorpting to radioactivity element and element replacement between Ga and Al in coal seam and Ga content increasing with ash content increasing in coal seam,the Ga content in coal seam can be computed using natural gamma logging data.
