摘要：为了深入分析海、陆相页岩微观孔陈的特征差异和含气潜力，采用FEIQuanta200F肠发射环境扫描电镜对页岩券样造行了高真空担猫，建立了微观储层孔隙结构体系。以起损电镜观测的赋观乱隙孔径大小、形态及连通性结果为基础，参考前人对页岩吸附气、游离气研究成果及吸气、游离气特征差异，对不同孔隙的储气能力和对页岩气的渗滤扩散的控制作用遗行了研究，将陆相页岩和海相页岩的微观孔隙进行对比分析，总结海、陆相页岩微观孔隙的特征差异和含气潜力。研究结果表明，页气6类储层孔隙中，有机质纳来孔、黏土矿物粒间孔富集海、陆相页岩吸附气，古生物化石孔、岩石骨架矿物孔、黄铁矿品间溶蚀孔、累缝富集游离气，改造后的岩石骨架矿物孔和微聚缝在页岩气的渗滤扩散方面超到主要作用。海相页岩中有机质和有机质纳来孔的含量远高于陆相页岩，而纳来孔富集吸附气；海相包含较多石英、长石及碳酸盐矿物，使海相页岩能性矿物的含量高于陆相页岩，更易压裂，以上两个固素导致海相页券的开发潜力大于陆相，

eese continental shale, high vacuum scanning was carried out on shale samples by using FEI Quanta 2o0F field emission environmental scan-ning electron microscope (FE-ESEM), and the structural systems of microscopic reservoirs pores were established. Then, the gas storage capacity of different pores and the their controlling effect on the scepage and diffusion of shale gas were investigated based on the size, morphology and connectivity of microscopic pores observed through SEM, combined with the former research results of shale adsorbed gas and free gas and the characteristic differences between adsorbed gas and free gas. The microscopic pores in marine and continental shale were compared. And finally, the characteristic differences and gas bearing potential of microscopic pores in marine and continen-
