【摘要】：通过大量取心井资料的统计分析,建立了高煤阶煤岩的测井多参数识别标准,并采用灰色关联法定量解释煤岩的类型,不受人为因素影响,准确率高。高煤阶煤岩的密度与工业组分含量之间关系密切,把测井多元回归模型和等效体积模型结合,计算出了煤岩的密度和孔隙度,并在此基础上计算出煤岩各工业组分的含量。该方法是在大量实验数据基础上,把理论模型与实际统计模型结合建立起来的方法,其结果比较可靠,并且在实际操作中可行。
[Abstract]:Based on the statistical analysis of a large number of coring well data, a multi-parameter identification standard for logging of high-rank coal and rock is established, and the grey correlation method is used to interpret the type of coal and rock, which is independent of human factors and has high accuracy. The density of high-rank coal and rock is closely related to the content of industrial components. The density and porosity of coal and rock are calculated by combining the multivariate regression model of logging with the equivalent volume model, and the contents of each industrial component of coal and rock are calculated on this basis. The method is based on a large number of experimental data and combines the theoretical model with the practical statistical model. The results are reliable and feasible in practice.
