储层孔隙结构研究主要有铸体薄片、X射线CT扫描、扫描电镜、压汞法、三维成像和核磁共振等多种手段。储层孔隙结构目前存在的问题主要表现在研究中定性和定量研究结合不够紧密，传统的压汞法具有局限性，空间分辨率不足在一定程度上限制了其在非常规油气储层孔隙结构研究中的应用，储层孔隙结构研究中样品较小，不具有整体代表性。储层孔隙结构研究的发展趋势主要表现在储层孔隙结构分类与评价、通过引入新的技术提高空间分辨率及对非常规储层孔隙结构进行研究，多种手段相结合开展储层综合研究，提高评价准确度等方面。%Reservoir void structure identification depends on various means such as casting lamella ,X -ray CT scanning ,scanning electron microscope ,mercury intrusion method ,three -dimensional imaging and NMR .Main problems existing in Reservoir void structure identification are that qualitative and quantitative research aren't closely binding ,traditional mercury intrusion method has limitation ,insufficient space resolu‐tion limits its application in unconventional oil-gas reservoir void structure identification ,and smaller speci‐men doesn't possess overall representation .Growing trend of reservoir void structure research includes clas‐sification and evaluation of reservoir void structure ,enhancing space resolution by brining in new technolo‐gies and implementing comprehensive reservoir research to make the evaluation more accurate .
