摘要
采用灰分与自然伽马正相关归位法,对韩城矿区煤芯进行了归位。并用趋势面分析法对测井资料进行了标准化,利用密度和声波计算了波阻抗曲线。在此基础上,对各井中11号煤层煤芯的煤体结构与相对应的波阻抗、中子、密度、自然伽玛等测井参数的相关性进行了分析。结果表明,声波阻抗和补偿中子测井响应的交汇分析方法,可以较准确地划分出煤体结构。
We use coal ash content with logging gamma curve to locate the core of Hancheng demonstration area,and apply trend surface analysis to carry on the normalization for logging data,use density and sound wave in the logging data to set up the wave impedance curve. Then we study the relationship between coal body structure of the core samples at 11#coal seam and corresponding wave impedance,neutron,density,natural gamma logging and other relevant parameters. The results show that using the crossplot technique of wave impedance,compensated neutron response and the coal body structure can classify accurately.
