Characteristics of Hydraulic Fracture in Homogeneous Porous Rock Material Based on EPHF Model
Abstract
Based on a coupled fluid-solid theory, an extended permeability-based hydraulic fracture(EPHF) model was developed according to the permeability-based hydraulic fracture(PHF) model. The proposed EPHF model assumed that the permeability of porous rock was a function of mean effective stress when a rock was fractured. The porous elastic constitutive law and Drucker-Prager plastic model were adopted to model the pre-failure and post-fracture …
