..., while a discrete fracture model is employed to characterize medium and long fractures. Further, a numerical well-testing model for ultra-deeply fractured low-porosity sandstone reservoirs is established, namely a multi-scale dual porosity dual-zone composite model. Results show that the flow regimes can...

... Abstract The complex geology of fold-and-thrust belt led to significant difficulties with the engineering aspects of drilling, logging, completion, and testing. The Bashijiqike Formation and Baxigai Formation feature a tight sandstone reservoir that exists below a salt layer with high pressure...
