应用回归分析进行原煤灰分预测

煤层的原煤灰分分析研究是煤质分析的重要内容。作者应用系列Ⅲ数字测井仪在山西河东煤田、河南永城煤田及安徽淮南煤田等地开展近百口井的测井工作,取得了大量的原始数据,为利用测井资料研究煤层的原煤灰分提供了极有利的条件。本文就概率模型分析法之一的回归分析法的方法内容和分析结果进行了介绍。

THE PROGNOSIS OF ASH CONTENT IN RAW COAL BYMEANS OF REGRESSION ANALYSIS

The study of ash content in raw coal is an important part of coal quality analysis. Using Series Ⅲ digital logging instrument, the author conducted log ging work along nearly one hundred boreholes in Heche coalfield of Shanxi pro vince, Yongcheng coalfield of Henan province and Huainan coalfield of Anhui province and thus acquired large quantities of initial data. This has laid a so lid foundation for the application of logging data to the study of ash content of raw coal in the coal bed. This paper describes the techniques and analyti cal results of regression analysis, one of the probability model analytical me thods.
