摘要 为了查明泥页岩系统微观孔隙发育特征及其油气地质意义,利用扫描电镜及场发射扫描电镜二次电子成像技术对松辽盆地白垩系青山口组一段泥页岩中的微观孔隙进行了系统观察。该套泥页岩中主要发育了5种类型孔隙,即基质晶间孔、有机质孔、溶蚀孔、粒间孔、晶内孔;此外,还发育大量微米—亚微米级(纳米级)微裂缝,包括溶蚀缝、充填缝及层间缝3类。微孔隙和微裂缝构成复杂微裂缝网络-孔隙系统,为烃源岩生成的油气向外排驱提供了有效通道,同时也为残留在页岩中的油气提供了充分的储集空间,对于油气的初次运移以及页岩油气等非常规资源的储集具有重要意义。 To research the characteristics and petroleum geological significance of micro pores,this paper uses Second Electron Microscope(SEM) and secondary SEM imaging capability in Field Emission SEM(FE-SEM) to characterize shale from the first member of the Cretaceous Qingshankou Formation,Songliao Basin.There are five major pore types in the shale,including matrix intercrystal,organic,dissolution,interparticle,and intracrystalline pores.In addition,there are a mass of micro-fractures of micron-submicron(nano-) scale,including dissolution,filled and interlayer fractures.The existence of complex fracture-pore systems provides an effective pathway for primary migration and it also provides ample storage space for the residual petroleum in shale,which is important for the primary migration and storage for shale oil and gas resources.
