摘要
基于压汞实验,分析了新疆阜康矿区9个煤样煤储层压汞孔隙分布特征,利用分形理论定量计算了煤样的孔隙分形维数,对煤样进行镜质组反射率测定、煤质分析,分析了煤的分形维数特征。研究表明,煤孔隙体积分形维数与水分呈正相关关系,灰分对分形维数也有重要的影响,随着分形维数的增加储层孔隙度相应增加。
Based on the mercury injection experiment,the coal reservoir pressure mercury pore distribution characteristics of nine coal samples from Fukang mine area in Xinjiang were studied. On the basis of the quantitative calculation by using fractal theory in the coal sample' s pore fractal dimension,and the coal samples were determined,the vitrinite reflectance of coal quality,and analyzes the fractal dimension characteristics of coal. Research has shown that coal pore volume fractal dimension and moisture content are positively correlated,ash has an important influence on the fractal dimension,with the increase of fractal dimension of the reservoir porosity also increases accordingly.
