原子力显微镜（AFM）是一种用于研究表面特征的相对较新的工具，可以生成原子分辨率的图像特征。AFM不仅可以获得表面的形貌图像，而且可以同时以高分辨率识别表面上的不同材料。自20世纪80年代发明以来，AFM已被用于材料科学和医学研究，尽管它在油藏工程中尚未得到应有的关注。然而，非常规页岩气藏的出现为AFM在油藏工程领域开辟了新的研究前沿。AFM的独特功能使其成为研究页岩中纳米孔、有机材料（干酪根）、矿物和成岩裂缝的理想工具。它还可以用来测量表面上的局部体积弹性模量，以进一步影响地球物理勘探和水力压裂设计。我们介绍了不同的AFM技术，所有这些应用程序，沿着的例子结果。
An atomic-force microscope (AFM), a relatively new tool for studying surface characterization, can generate image features down to atomic resolution. Not only can the AFM obtain topographic images of surfaces, but it also can simultaneously identify different materials on a surface at high resolution. Since its invention in the 1980s, AFM has been used in material science and medical research, although it has not received the attention that it probably deserves in reservoir engineering. The emergence of unconventional shale-gas reservoirs, however, has opened new research frontiers for the AFM in the field of reservoir engineering. The unique capabilities of the AFM make it ideal for studying nanopores, organic materials (kerogen), minerals, and diagenetic fractures in shales. It also can be used to measure localized bulk modulus of elasticity on a surface for further implications in geophysical exploration and designing hydraulic fracturing. We introduce different AFM techniques for all these applications, along with example results.
