Small-angle neutron scattering (SANS) and ultrasmall-angle neutron scattering (USANS) are special and powerful tools to study micro-, meso-, and macropores from 1 nm to 10 μm in size in disordered systems. Neutron scattering measurements are often integrated with fluid-invasion methods to provide a comprehensive understanding of the pore space in shale. The first SANS study of shale samples was dated back to the early 1980s. The interest was renewed around 2011, and the number of studies that applied SANS/USANS spectra to shale has increased rapidly during the past few years. Several key developments in data analysis were noted in literature studies. In this mini review, technical aspects of sample preparation and data analysis were discussed. This paper offers a quick guide for those who are new to this field.

小角度和超小角度中子散射测量页岩孔隙结构的技术方面：迷你回顾

小角中子散射（SANS）和超小角中子散射（USANS）是研究无序系统中尺寸从1 nm到10μm的微孔，中孔和大孔的特殊而强大的工具。中子散射测量通常与流体侵入方法结合使用，以提供对页岩孔隙空间的全面了解。SANS对页岩样品的首次研究可追溯到1980年代初。在2011年左右重新引起了人们的兴趣，在过去几年中，将SANS / USANS光谱应用于页岩的研究数量迅速增加。文献研究指出了数据分析中的一些关键发展。在这篇小型综述中，讨论了样品制备和数据分析的技术方面。本文为该领域的新手提供了快速指南。
