| 英文摘要 | Permeability anisotropy and non-Darcy effect are critical factors in determing the production capacity of gas shale. Through combined testing using the cubic-block and crushed-particle sample methods, we systematically characterized the percolation characteristics of 27 samples from the main production layer (S1l(1-1)(1) sublayer) of the Longmaxi Formation. Results show the quartz matrix support system dominates percolation perpendicular to bedding, with permeability (K-V approximate to 1-500 nD) showing high consistency with crushed sample results (K-C), controlled by porosity-quartz content co-evolution. However, clay directional alignment significantly enhances bedding-parallel percolation advantage (K-P/K-V = 10(1)-10(3)), with every 5 % increase in clay content elevating K-P by approximately one order of magnitude. Based on Knudsen number (Kn), we demonstrate that Darcy flow and slip flow are the main flow forms while pure Knudsen flow is rare in shale gas development. Finally, an integrated evaluation framework of permeability to optimize shale gas exploration is developed by incorporating with actual well performance. From the perspective of permeability, reservoirs with Kn < 0.2 and K-P/K-V < 100 exhibit better exploration and development potential. |
