新集矿区煤的孔渗性实验室测定研究

Laboratory measurement of coal permeability in Xinji mining area

    摘要
  • 摘要: 采用新集矿区煤样进行实验室条件下孔渗性测试分析,研究该区煤在不同围限压力下有效孔隙度和气体渗透率的动态变化趋势;同时,对孔渗性的实验室测试方法的可行性,结合该区试井测试结果分析比较,提出测试结果适用性评价。

     

    Abstract: The laboratory measurement of coal permeability of in Xinji mining area is conducted to research effective porosity underthesurrounding limited pressure and dynamic change trend.The feasibility of laboratory measurement method is discussed by comparing well testresults and the availability of measurement is provided.
