基于流体识别因子的煤矿岩层含水性特征研究新方法
|
摘要
为了评价矿区含水岩层的含水性特征,基于矿区地球物理测井资料,对含水岩层测井响应特征进行综合研究,统计分析多项岩石物理参数,构建有效的流体识别因子,对含水性特征进行敏感性分析,优选对含水性敏感的岩石物理参数,在此基础上,提出一种新的岩层含水性特征判别指标。实践应用表明,利用该判别指标评价的岩层含水性特征与钻探成果基本一致,得出矿区山西组砂岩裂隙水含水性弱,而奥陶系灰岩岩溶裂隙承压水含水性好,是矿区主要的充水水源。该判别指标充分考虑岩层含水性对岩石物理参数的影响,是矿区常规水文地质条件评价方法的有效补充。
In order to appraise the water bearing characteristics of rock in coal mine,on the basis of geophysical logging data of mine areas,the authors studied systemically logging response of water bearing rock beds,counted enough geophysical parameters of rock,and proposed fluid identification factors,meanwhile,through researching the sensitivity of kinds of geophysical parameters of rock,and choosing them,a new discrimination index on water bearing rock beds was proposed based on the research of sensitivity of geophysical parameters. The practical application indicates that,the result of discrimination index on water bearing rock beds and the drilling results are similar,and shows that the water content of Shangxi Formation sandstone fissure water is low,and the water content of Ordovician limestone fissure water is high,which belongs the main water resource in this region. The discrimination index takes better account of influence of geophysical parameters of rock on the water-containing nature,and it is a new additional method to appraise the water-containing nature compared with conventional method.
