摘要: Favorable prospects for the exploration of shale gas have been demonstrated in Ordos Basin, China. Outcrop and core observations indicate that there are abundant laminas strata, which exert a great influence on hydro-fracture propagation, storage fluid flow. In this study, continental Chang 72 Member, collected from south was investigated to characterize geometric heterogeneity. Laminas at multiple scales were observed measured using conventional logging, borehole TV, analysis, scanning electron microscopy, Particle Crack Analysis System. These measurement tools correspond meter scale, decimeter centimeter millimeter scale ten-micrometer respectively, with thicknesses 2.26 m, 2.09 dm, 1.70 cm, 1.48 mm 11.70 μm, respectively. Fractal theory used analyze power exponent distribution lamina thickness, resulting fractal dimension 1.06. Finally, heterogeneity model proposed Upper Triassic Yanchang Formation study area verified by modeled thickness 26.30 m Member 10-m scale. The facilitates cross-scale analysis provides parameter guidance characterization numerical simulation test reservoir.
