3D reconstructed model and numerical simulation of hydrofracturing of low-permeability heterogenous glutenite
Understanding of the initiation and propagation mechanism of hydraulic fracturing cracks in heterogeneous glutenites is significant to the efficient stimulation of the unconventional oil and gas reservoirs.Natural glutenite reservoirs involve lots of gravels with irregular geometry and different sizes,which are extremely difficult to handle with in the most numerical simulations.The complex geometry of gravels,particle sizes,interconnection and coalescence of cracks,and interactions between particles and cracks are the main difficulties and challenges in numerical simulation of the hydrofracturing behavior of heterogeneous glutenites.In this paper,based on the continuum-based Discrete Element Method(CDEM),the authors proposed a promising way to solve the problems and obtained the propagation characteristics and the spatial distribution of the hydraulic fracturing cracks of glutenites.The simulations were validated through comparing the results with the experiment data.
