▎ 摘  要

NOVELTY - Hydraulic fracturing involves formulating a hydraulic fracturing fluid comprising a liquid solvent, one surfactant, a liquid phase proppant-forming compound, one curing agent, injecting the hydraulic fracturing fluid into a wellbore, generating a product of agglomerated individual solid beads from the hydraulic fracturing fluid in-situ under down hole conditions, and forming pillars from the product of agglomerated individual solid beads in a two-dimensional structure capable of maintaining conductive fractures in a downhole environment. USE - Hydraulic fracturing used for oil and gas recovery improvement. ADVANTAGE - The method improves fracture conductivity.
