摘      要：本文综述了砂岩孔隙结构在非常规油气资源勘探与开发中的重要性,并探讨了不同评估方法的适用性。文章首先强调了砂岩孔隙结构对油气储存和流动特性的影响,以及其对提高采收率和优化勘探开发策略的关键作用。接着,文章介绍了间接测定法(如压汞法、半透膜法、离心法)、直接观测法(如铸体薄片法、扫描电子显微镜、计算机断层扫描)和测井资料评价方法(如电阻率法、核磁共振法、声波时差法)等技术,并分析了它们的优势与局限性。最后,文章得出结论,砂岩孔隙结构的研究对油气资源的有效开发至关重要,有助于保障能源安全、推动技术进步、保护环境以及实现社会经济的可持续发展。随着技术的发展,未来有望进一步提升油气资源的开采效率,实现资源的充分利用,为全球能源的持续发展贡献力量。This article reviews the importance of sandstone pore structure in the exploration and development of unconventional oil and gas resources and discusses the applicability of different evaluation methods. The article first emphasizes the impact of sandstone pore structure on the storage and flow characteristics of oil and gas, as well as its key role in improving recovery rates and optimizing exploration and development strategies. It then introduces indirect measurement techniques (such as mercury injection, semi-permeable membrane, and centrifugation methods), direct observation methods (such as thin section casting, scanning electron microscopy, and computed tomography), and logging data evaluation methods (such as resistivity, nuclear magnetic resonance, and sonic time difference methods), and analyzes their advantages and limitations. Finally, the article concludes that the study of sandstone pore structure is crucial for the effective development of oil and gas resources, contributing to energy security, technological progress, environmental protection, and sustainable socio-economic development. With technological advancements, it is expected that the efficiency of oil and gas resource development will be further improved in the future, realizing the full utilization of resources and contributing to the sustainable development of global energy.
