摘　　要：页岩储层的勘探开发与页岩储层的微观孔隙特征及页岩油可动用程度的定性定量表征密切相关。近年来,随着先进技术的发展,非常规储层地质勘探方面有了巨大进展。通过对微纳米孔喉结构精细表征技术的调研,将其分为数据分析技术及图像观测技术两部分进行定性定量表征技术介绍。其中,除主流的表征技术之外,详细介绍了在微纳米孔喉结构研究上具有一定优势但尚未完全普及低场核磁共振冻融技术、伍德合金高压注入技术,其优势主要体现在纳米孔喉的定性定量表征上,尤其是连通性的表征上。总结了伍德合金高压注入技术结合图像观测技术及后续图像数据处理的连通性定性定量表征方法,对页岩储层微观孔隙特征研究具有重要意义。The exploration and development of shale reservoir is closely related to the microscopic pore characteristics of shale reservoir and the qualitative and quantitative characterization of shale oil availability.In recent years,with the development of advanced technology,there has been great progress in unconventional reservoir geological prospecting.Through the investigation of fine characterization technology of micro/nano pore-throat structure,qualitative and quantitative characterization technology is introduced,which is divided into data analysis technology and image observation technology.Among them,in addition to the mainstream characterization techniques,two methods that have certain advantages in the study of micro/nano-pore throat structures but are not fully popularized are detailed,such as low field nuclear magnetic resonance(NMR)and Wood's metal high press injection technology(such as HP-WMI).Its advantage mainly embodies on the quantitative characterization of the pore throat,especially on the characterization of connectivity.The qualitative and quantitative characterization methods of Wood's metal high pressure injection technology combined with image observation technology and subsequent image data processing are summarized,which is of great significance to the study of microscopic pore characteristics of shale reservoir.
