摘要
文章针对目前煤田测井曲线资料利用率偏低的情况,通过对测井曲线进行数字化、标准化,统计和分析曲线参数幅值,建立地质物理性质参数与相关度高的测井曲线属性参数之间相关关系,获得测井曲线参数单因素或多因素属性模型,可对岩煤层储气特征、岩层水文地质条件及岩石力学性质等特征进行辅助解释。淮南矿区1煤层采区解释结果表明:综合利用测井曲线分别求得的复合参数与煤层瓦斯含气量之间具有极高相关性,与煤层顶板岩石抗压强度具有中度相关性;借鉴Archie公式所求得的采区岩层赋水性与巷道揭露的赋水特征基本一致。该方法可为测井曲线资料再利用提供一种有效手段。
In view of the situation of low utilization rate of logging data in coal exploration at present , the correlativity between geological physical property parameters and high relevancy logging property parameters is established through digitization and standardization of logging curve ,statistics and anal‐ysis on amplitude of curve parameters . Through obtaining property model of the single factor or multi‐factor ,the characteristic of gas storage in coal and rock stratum ,hydrogeological condition of stratum ,mechanical properties of rock and so on can be explained supplementarily .The interpretation results of No .1 coal seam in mining area of Huainan mining field show that the composite parameters obtained by comprehensive utilization of logging curve have an extremely high correlation with coal bed gas content and have a moderate correlation with tensile strength of coal seam roof ;the water characteristic in mining area obtained by referring Archie formula in oil has broadly matched with that by tunnel exposing .This method can provide a kind of effective means for use of logging data .
