    • Abstract
  • To determine the conductivity of channeling fractures under field conditions and to identify factors that may affect such conductivity, a fluid flow model has been established in accordance with distribution of fractured sand bars. In addition, a numerical simulation has been performed to determine flow patterns of fluids in certain fracture and to calculate conductivity of such fractures. Research results showed that structures and distribution of pore channels in channeling fractures were key factors that might affect the conductivity of fractures. In the case that no continuous large channels were generated, or such major channels collapsed to generate dispersedly distributed pore structures, fluids in the fracture might encounter significant flow resistance. Under such circumstances, conductivities of channeling fractures might be reduced significantly. Relevant research results might provide a solid foundation to enhance conductivity of channeling fractures.
