文摘

Combining FE-ESEM observation and N2 sorption experiment to characterize shale pores. Two fractal dimensions of shales are calculated and discussed. Pore development and genesis of high-maturity shales are investigated. Controlling factors of shale pore structure are investigated. Relationships between pore structure parameters and two fractal dimensions are studied.
