Simulation of proppant transport at intersection of hydraulic fracture and natural fracture of wellbores using CFD-DEM
文献摘要：
Proppants transport is an advanced technique to improve the hydraulic fracture phenomenon,in order to promote the versatility of gas/oil reservoirs.A numerical simulation of proppants transport at both hydraulic fracture (HF) and natural fracture (NF) intersection is performed to provide a better understand-ing of key factors which cause,or contribute to proppants transport in HF-NF intersection.Computational fluid dynamics (CFD) in association with discrete element method (DEM) is used to model the complex interactions between proppant particles,host fluid medium and fractured walls.The effect of non-spherical geometry of particles is considered in this model,using the multi-sphere method.All interaction forces between fluid flow and particles are considered in the computational model.Moreover,the inter-actions of particle-particle and particle-wall are taken into account via Hertz-Mindlin model.The results of the CFD-DEM simulations are compared to the experimental data.It is found that the CFD-DEM sim-ulation is capable of predicting proppant transport and deposition quality at intersections which are in agreement with experimental data.The results indicate that the HF-NF intersection type,fluid velocity and NF aperture affect the quality of blockage occurrence,presenting a new index,called the blockage coefficient which indicates the severity of the blockage.
