Abstract EN
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 gradually and the diameter increases as the closing stress increases.
In the fracturing fluid flowback period, proppant particles could be driven away from the pillar by the fluid flow and cause the instability of the proppant pillar.
The proppant flowback could occur easily with large proppant pillar height or a large fluid pressure gradient.
Both the pillar height and the pillar diameter to spacing ratio are key parameters for the design of channel fracturing.
Increasing the fiber-bonding strength could enhance the stability of the proppant pillar.
