The refinement of nanoscale physical parameters of source rocks has benefitted from continuous innovations in technology and methods. Traditional methods for detecting reservoir physical properties are limited by the properties of the instruments. Atomic force microscopy (AFM) provides new methods and approaches for furthering our understanding and exploring the nanoscale world. Its wide range of applications and gradually developed multiscenario application modes make it an ideal tool for the characterization of nanoscale physical properties of source rocks (coal, shale, mudstone, sandstone, etc.). We highlight the advantages of AFM in regard to performing nondestructive 3D imaging and mechanical property measurements with nanoscale resolution in any desired environment (air, vacuum, liquid). The limitations of AFM applied to source rocks are also summarized. The process has great potential in micro/nanopore characterization, surface morphology characterization, in situ micromechanical property acquisition, wettability research, and so on. The gradual development and improvement of this new model will expand new methods, bring enlightenment to basic research on unconventional oil and gas resources, and provide a scientific basis for the exploration and development of unconventional oil and gas resources.

原子力显微镜鉴定烃源岩的纳米级物理参数:综述

烃源岩纳米级物理参数的细化得益于技术和方法的不断创新。传统的储层物理特性检测方法受到仪器特性的限制。原子力显微镜 (AFM) 为加深我们对纳米级世界的理解和探索提供了新的方法和途径。其广泛的应用范围和逐步发展的多场景应用模式,使其成为表征烃源岩(煤、页岩、泥岩、砂岩等)纳米级物理性质的理想工具。我们强调 AFM 在任何所需环境(空气、真空、液体)中以纳米级分辨率进行无损 3D 成像和机械性能测量方面的优势。总结了原子力显微镜应用于烃源岩的局限性。该工艺在微/纳米孔表征、表面形貌表征、原位微机械性能获取、润湿性研究等方面具有巨大潜力。这一新模式的逐步发展和完善,将拓展新方法,为非常规油气资源基础研究带来启示,为非常规油气资源勘探开发提供科学依据。
