Abstract
The research on the optimization of hydraulic fracturing fracture morphology is an essential aspect of hydraulic fracturing design. However, suboptimal fracture morphology resulting in lower than expected production often occurs due to the mismatch between reservoir types and hydraulic fracturing operational parameters. Different geological sweet spot reservoirs require distinct optimal fracture morphologies. In this paper, we categorize reservoirs into types I, II, and III, considering them as preferred layers for hydraulic fracturing. Three geological models are established to investigate the impact of fracture length and fracture conductivity on post-fracturing productivity, aiming to determine the optimal fracture morphology. The findings of this research will provide a scientific basis for the development of tight sandstone gas reservoirs in the Ordos Basin.
