煤层煤质参数测井解释模型

LOG INTERPRETATION MODEL OF DETERMINING COALBED COAL QUALITY PARAMETERS

以确定煤质参数的体积模型法为基础，结合煤样实验室分析资料，利用概率模型法（多元线性回归）确定煤质参数的测井解释模型。经Ｆ检验，说明建立的方程组有效，线性关系显著。实际解释结果表明，解释模型估算的煤质参数与煤样实验室分析的煤质参数之间一致性好，解释精度高。

On the basis of the mothed of log equivalent volume model and the laboratory analysis information of coal samples, the authors develop the log interpretation model of determining coalbed coal quality parameters by the probable model method(multi variate liner regression method). The F test result shows that the equations which have been established are efficacious. The agreement between the coalbed coal quality parameters predicted by the interpretation model and those determined by the coal sample laboratory analysis can be seen clearly by the interpretation example. The conclusion is that the method which is concise and convenient to apply is effective, precise, and the study result is satisfactory.
