Utah FORGE 5-2615: Shear Enhanced Permeability In a Granitoid Fracture - Presentation Slides

Provided here is a set of presentation slides detailing stress-dependent permeability in FORGE granitoid fractures and how fracture slip affects permeability. It outlines empirical correlations between permeability, stress, and fracture aperture, emphasizing that mechanically closed fractures retain some permeability. Moreover, the presentation explains that moderate shear slip can increase permeability by enhancing fracture networks, provided the slip displacement does not produce gouge materials that could clog the fractures.

本处提供了一系列演示文稿，详细阐述了FORGE花岗岩裂隙的应力依赖性渗透率以及裂隙滑动如何影响渗透率。该文稿概述了渗透率、应力与裂隙张开度之间的经验相关性，并强调机械闭合裂隙仍保持一定的渗透性。此外，演示文稿还阐释了，在滑动位移不产生可能堵塞裂隙的磨蚀物质的前提下，适度的剪切滑动可以通过增强裂隙网络来提高渗透率。
