| Fig. 4. Oil-saturated and water-saturated T2 spectra of different types of pore-fracture configuration in shale reservoirs in western Chongqing area. (a) Pore-hydrocarbon-generating pressurized fracture contact; (b) Pore-clay fracture separation; (c) Pore-mineral dissolution fracture separation; (d) Pore-compacted fracture separation; (e) Structural micro-fracture contact; (f) Organic matter edge fracture contact. |
