摘　　要：介绍了干馏后油页岩在三轴应力下的渗透实验,揭示了干馏后油页岩的渗透规律,通过多元回归分析得到了干馏后油页岩的渗透系数与体积应力、孔隙压的关系式,表明了它的渗透系数与体积应力、孔隙压呈指数关系。并经过分析可知,若其埋藏深度较浅,可以通过增加孔隙压来改善它的渗透性;若其埋藏深度较深,则可以通过采取适当的措施,提高其渗透系数。这一结论对油页岩的原位开发与利用具有重要参考价值。The test on seepage of distilled oil shale in three dimension stress state has been carried out, and then the relations among the coefficient of seepage, volumetric stress and pore pressure have been exposed. By analyzing the results of the test the authors obtain a experiential curve about the coefficient of seepage, volumetric stress and pore pressure. Then effective methods of enhancing seepage of distilled oil shale are discussed in different depth. The result achieved is important to in-situ exploit oil shale.
