页岩气和石油日益成为一种非常重要的非常规能源。因此,它是至关重要的多孔结构和表面动力学,如微润湿性和扩散,这些非常规资源的估计和恢复的特征。由于页岩中存在突出的纳米多孔结构,核磁共振(NMR)可能是目前唯一有效和强大的工具,用于调查和表征页岩中的纳米多孔结构和动力学。本文综述了各种核磁共振方法,包括核磁共振弛豫法、核磁共振低温孔隙度法和快速场循环(FFC)核磁共振法,并指出了这些方法的优点和局限性。审查还确定了与这些应用程序经常在文献中看到的谬误。核磁共振的潜力可以进一步开发,因为这里用于非常规能源的方法也可以应用于其他有趣的多孔介质。
Shale gas and oil have increasingly become a very important unconventional energy resource. As such, it is critical to characterize the porous structure and surface dynamics such as microwettability and diffusion, for the estimation and recovery of these unconventional resources. Due to the salient nanoporous structures present in shales, nuclear magnetic resonance (NMR) may currently be the only efficient and powerful tool for investigating and characterizing the nanoporous structures and dynamics in shales. This review discusses various NMR methods including NMR relaxometry, NMR cryoporometry, and fast field cycling (FFC) NMR and identifies the merits and limitations of these approaches. The review also identifies fallacies associated with such applications often seen in the literature. The potential of NMR can be exploited further as the methods used here for unconventional energy resources can also be applied to other intriguing porous media.
