In this study, proppant pillar deformation and stability during the ,fracturing fluid flowback, of channel ,fracturing, was simulated with DEM-CFD- (discrete element method-computational ,fluid, dynamics-) coupling method. Fibers were modeled by implementing the bonded particle model for contacts between particles. In the hydraulic fracture-closing period, the height of the proppant pillar decreases ...
