| 摘 要： | 煤层气储层地球物理测井评价是获取煤层气参数的重要方法。根据沁水盆地柿庄区块煤层气储层的典型地质特征及该区块的测井资料和岩心分析数据，基于体积模型和概率统计模型的分析方法，计算出煤层各组分含量；对大量的测井资料进行统计分析，得出该区煤层煤阶与地层温度相关的结论；基于概率统计模型计算出的煤层组分和实验室岩心解吸测试数据，利用兰氏方程和多元线性回归导出了煤层含气量计算的经验公式，并通过该区的实际资料验证了评价方法的可信度与有效性。

Technology for evaluation of CBM reservoir logging and its application |

| Abstract: | Geophysical logging evaluation is an important method to obtain coalbed methane parameters. According to the typical coal seam geological characteristics of Shizhuang block in Qinshui basin and logging data as well as core analysis data, the authors figured out each component of coal seam based on the volume model and the probability statistical model. The conclusion is deduced that coal rank is closely related to formation temperature in this block after analyzing logging data and coal core data; Taking a research on analyzing the relationship of coal component calculated by probability statistical model and core data tested in laboratory, empirical formula of calculating gas content is deduced with Langmuir equation and multiple linear regression method. At last, it is proved that the methods possess the credibility and availability through the application with actual data. |
