摘　　要：为了研究油页岩在不同温度下孔隙结构的变化特征,利用压汞法测定油页岩在不同温度与压力下的孔径、孔容积。实验结果表明:油页岩的孔容积随着温度的升高而增大,在整个温度变化过程中,中孔(0.1~1μm)和小孔(0.01~0.1μm)的分布始终处于相对稳定的状态。In order to study the variation characteristics on pore structure of oil shale under different temperatures,the pore size and pore volume of oil shale under different temperatures and stresses were measured by mercury intrusion method.The experimental results showed that pore volume increased with the rise of temperature,and the distribution of mesopore(0.1 to 1μm)and minipore(0.01 to 0.1μm)was always in a relatively stable state during the whole temperature variation.
