平顶山五矿己_16—17煤裂隙分形特征及其研究意义

摘要: 平顶山五矿己_16-17煤中裂隙的计盒维数法量测结果表明,分维数在1.0~1.3之间,且距断层越近分维数值越大,为断层的预测提供了一种可供参考的定量方法;同时探讨了分维数在煤层气储层评价中应用的可能性。

Abstract: The measuring results of box counting dimension method of the fractures in Ⅵ_16-17coal of No.5 Mine,Pingdingshan,show that the fractal dimensions range from 1.0 to 1.3,and the shorter the distanec to the fault,the greater the fractal dimension.Therefore,the fault can be predicted quantitatively.Finally,the possibility for application of the fractal dimension to the coallbed methane reservoir assessment is discussed.
