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 intrusion experiments, the pore distribution characteristics of mercury in nine coal samples from the Fukang mining area in Xinjiang were analyzed. The fractal dimension of the samples was calculated by fractal theory. The vitrinite reflectance, Quality analysis, analysis of coal fractal dimension characteristics. The results show that the pore volume fractal dimension of coal has a positive correlation with the water content, and the ash content has an important influence on the fractal dimension. As the fractal dimension increases, the reservoir porosity increases correspondingly.
