鄂尔多斯盆地煤储层孔隙分形特征研究
Research on characteristics of fractures of coal reservoirs porosity in the Ordos Basin
【摘要】 在分析鄂尔多斯盆地煤储层压汞孔隙分布的基础上,定量计算了各煤样的分维数,并分析了煤的孔容分维数特征。研究结果表明,煤储层孔容分维数在3.0741-3.4371之间。随着分维数的增加,煤变程度和压汞效率减小。而储层孔隙率的增加,储层渗透率变大。提出孔隙分维数可作为煤层气储层渗透性评价的指标之一。
【Abstract】 Based on the distribution of micro-pores of coal reservoirs in Ordos Basin by CrloErbar 2000, the volume fractal dimension of micropores is quantitatively calculated and the characteristics are analyzed. The results of study indicate that the fractal dimension is between 3.0741 and 3.471 and the coal range dimensional and mercury penetration efficiency decreases, but reservoir porosity and reservoir permeability increases with the increase of the volume fractal dimension.
