煤储层多尺度裂隙特征及其对渗透性的控制=Characteristics of Multiscale Fractures in Coal Reservoir and Their Control on Permeability.pdf

煤储层是一种具有双重孔隙-裂隙型储层，孔隙是煤层中气体储存的主要空间；裂隙是煤层中流体运移的主要通道，是影响和控制煤储层渗透性的直接因素。本书采用理论分析、室内实验测试与数值模拟等多学科理论与方法，对煤储层多尺度裂隙参数进行了精细定量表征，系统研究了煤储层中宏观裂隙、微米级裂隙和纳米级裂隙结构演化特征及其主控因素，探讨了煤储层多尺度裂隙结构对煤储层渗透性的控制机理。
