摘要为研究油页岩在微波辐射下的渗流特性演化规律，采用高分辨率X射线CT扫描技术对微波热解后的抚顺油页岩进行可视化分析。通过三维图像重建技术获取油页岩的三维孔隙结构，并对渗流和压力场的特征信息进行量化分析。结果表明：(1) 微波功率对抚顺油页岩孔隙结构的影响较大。800 W和600 ℃的条件下，油页岩的孔隙率为16.61%；在400 W和600 ℃条件下，油页岩的孔隙率为8.42%。孔隙和裂隙的分布和形态也受到微波功率的影响。(2) 较高的微波功率可以提高油页岩的分形维数及孔隙的长宽比，使表面更加粗糙且孔隙结构更为复杂，孔隙度更高，更容易发展成裂缝，这些都会提高油页岩的可渗透性。(3) 通过对中等流速值和孔隙中等压力值的分析，发现800 W微波功率下的中等流速值是400 W微波功率下的中等流速值的1.25倍，是600 W微波功率下的中等流速值的8.68倍，中等压力值随微波温度与功率的提高而降低。这些研究结果增强了对微波辐射油页岩热效应的理解，并发现了微波功率对油页岩孔裂隙结构和渗透性具有显著性影响。

Abstract：In order to study the evolution of seepage characteristics of oil shale under microwave radiation，high-resolution X-ray CT scanning technology was used to visualize and analyze Fushun oil shale after microwave pyrolysis. The three-dimensional pore structure of oil shale was obtained by 3D image reconstruction technology，and the characteristic information of seepage flow and pressure field was quantitatively analyzed. The results show that：(1) microwave power has a great influence on the pore structure of Fushun oil shale. At 800 W and 600 ℃，the porosity of oil shale is 16.61%. At 400 W and 600 ℃，the porosity of oil shale is 8.42%. The distribution and morphology of pores and fissures are also affected by microwave power. (2) Higher microwave power can improve the fractal dimension and pore aspect ratio of oil shale，make the surface rougher and pore structure more complex, higher porosity，and easier to develop into cracks, which will improve the permeability of oil shale. (3) Through the analysis of medium flow rate value and pore medium pressure value, it is found that the medium flow rate value at 800 W microwave power is 1.25 times the medium flow rate value at 400 W microwave power and 8.68 times the medium flow rate value at 600 W microwave power，and the medium pressure value decreases with the increase of microwave temperature and power. These results enhance the understanding of the thermal effects of microwave radiation oil shale，and find that microwave power has a significant effect on the pore structure and permeability of oil shale.
