纳米压痕是一项正在逐渐被石油和天然气行业接受的新技术。为了加速它的采用，我们回顾了它的功能和应用。这项技术是为了研究薄膜和半导体性质而开发的。当焦点转向非常规页岩时，它对石油和天然气行业变得有吸引力。由于页岩的易碎性和不稳定性，在许多情况下，取回岩心塞进行标准测量是不可能的。纳米压痕非常适合于测量细晶材料和材料碎片的性质。我们记录了如何使用纳米压痕来测量杨氏模数、硬度、剪切模数、各向异性、蠕变和断裂韧性，并检验页岩中这些特性的流体敏感性。
Nanoindentation is a new technology slowly gaining acceptance in the oil and gas community. In an effort to accelerate its adoption, we review its capabilities and applications. The technology was developed to study thin film and semiconductor properties. It became attractive to the oil and gas industry when focus switched to unconventional shales. Because of the friability and instability of shales, retrieving core plugs for standard measurements became impossible in many cases. Nanoindentation is perfectly adapted to measuring the properties of fine-grained materials and material fragments. We document how nanoindentation can be used to measure Young’s modulus, hardness, shear modulus, anisotropy, creep, and fracture toughness and to examine the fluid sensitivity of these properties in shale.
