密度测井在山西和顺地区煤层气储层评价中的应用

摘要

This paper systematically introduced the application of density log in CBM reservoir evaluation in Heshun area. In terms of coal seam division, because of the typical low density of coal, density log is the main method of the logging identification and the coal seam division. By analyzing density data and experimental data, density log can also be used to induce the equation of log in-dustrial analysis, porosity, gas saturation and other parameters. The analysis shows that density log covers multiple aspects of CBM reservoir evaluation and plays a key role in logging interpretation of CBM.%系统地总结了密度测井在和顺地区煤层气储层评价中的应用。在煤层划分方面，煤层特有的低密度特征使得密度测井成为测井识别、划分煤层的主要手段；通过密度数据与实验测试数据的数值分析，可以回归测井计算工业分析、孔隙度、含气量等多个参数的关系式。分析表明：密度测井的应用涵盖了煤层气储层评价的多个方面，在煤层气测井解释中具有关键作用。
