摘　　要：以淮南矿区构造煤储层评价为基础,利用灰色关联分析对16个单元煤储层物性参数进行定量评价。对评价结果与原专家打分法的评价结果进行比较分析,二者吻合率达62.5%;灰色关联分析法是一种定量评价构造煤储层确实可行的方法,具有推广应用的广阔前景;构造煤储层评价是一个复杂的、多重因素参与的评价过程,用灰色关联分析进行储层评价,可以使评价结果量化,而且可以从综合的角度分析各个参与评价的参数,使不精确的表达和处理方法数字化,可提高储层综合评价的科学性。Based on the evaluation of tectonic coal reservoir in Huainan mining area, adopted the grey relational analyses to quantitatively evaluate the physical parameters of 16 coal reservoir units. We ana- lysed and compared two evaluation results obtained from grey relational analysis method and expert evaluation method, with the result that the coincidence rate was 62.5%. The grey relational analysis meth- od is a feasible method for evaluating the tectonic coal reservoir quantitatively, and can be widely used in engineering practice. The tectonic coal reservoir evaluation is a complex process, in which multiple factors involved. Using gray relational analysis method for reservoir evaluation, we can quantify the evaluation results, analyze all evaluation indexes involved in process from comprehensive view, digitalize the inaccurate expression and processing method, and improve the accuracy of comprehensive reservoir evaluation.
