【摘要】 页岩储层孔隙类型多样,以纳米级孔隙为主,裂缝不发育或很少发育,微裂缝相对发育。有机质丰度与粘土矿物含量是纳米级孔隙发育的主要控制因素。不同的纳米级孔径分布对吸附气及游离气含量影响不同。更多还原

【Abstract】 Shale reservoir is complicated in its pore type,and the main type is nanopore.The fractures are not developed or rarely developed,and the micro-fractures are relatively developed.The abundance of organic matter and clay mineral content are the main control factors for the development of nanopores.Different nanoscale pore size distribution has different effects on the contents of adsorbed gas and free gas.更多还原
