煤层工业组分的计算一直是煤层评价的关键课题。以沁水盆地3#、15#煤层为研究对象,通过煤岩测试标定测井资料,研究了回归分析法和约束最优化算法在煤岩工业组分计算中的应用效果。应用实例显示:当煤岩测试资料充足时,基于煤岩刻度测井技术进行统计建模,可获得符合地区规律的回归分析模型,效果较好;当测试资料不足时,采用基于体积模型方法的约束最优化算法,结果较为合理。
The calculation of industrial components in coalbed has always been a key issue in coalbed evaluation. Taking 3# and 15# coalbed in Qinshui Basin as the research object, this paper studies the application effect of regression analysis method and constrained optimization algorithm in the calculation of industrial components combined with the coalbed test data. The application examples show that when the testing data of coalbed is sufficient, statistical modeling based on coalbed calibration logging technology can obtain a regression analysis model in accordance with regional laws with good results.When the test data is insufficient, the constrained optimization algorithm based on the volume model method is adopted, and the result is more reasonable.
