本文针对煤田密度测井的特点,首先讨论了根据煤心化验资料求出煤层的~Z/A校正方程,以及煤层分析体积百分比换算为重量百分比的方法。为适应计算机测井系统的需要,给出了补偿密度测井仪简化响应方程,用计算机取代模拟解算装置求解地层密度。最后根据简化响应方程,讨论了密度测井的误差分析和测量技术条件的选择。
In this paper, according to the characteristics of coalfield density logging, the ~ Z / A calibration equation of the coal seam based on the coal core laboratory data and the method of converting the volume percentage of the coal seam to the weight percentage are discussed. In order to meet the need of computer logging system, a simplified response equation of compensation density logging tool is given, and a computer replaces the simulation solution device to solve the formation density. Finally, according to the simplified response equation, the error analysis of density logging and the selection of measurement technique conditions are discussed.
