Abstract

Previous researches suggest that the hydraulic fracturing in unconsolidated sand is affected by many factors. However, the formation process of the fractures in unconsolidated sands has not been sufficiently clarified. Based on this situation, an original Distinct Element Method (DEM) code corresponding to unconsolidated sands was developed, and the mechanism of the hydraulic fracturing in the unconsolidated sands was discussed by flow-coupled DEM simulation. The model in this study has the ability to form various fracture formations depending on the permeability of the model and viscosity of the fracturing fluid. The fracture growth pattern that is observed in these simulations can be classified to no fracture, cavity expansion and linear fracture. Linear fractures formation in this simulations varies depending on the fluid mobility. Short fracture, long fracture and fracture that formed in two directions can be observed in our simulations.
