A Model for Multiple Hydraulic Fracture Propagation with Thermo-Hydro-Mechanical Coupling Effects

In this study, a coupled thermo-hydro-mechanical model to simulate multiple hydraulic fracture propagation is presented. Fracture with elastic deformation described by using displacement discontinuity method. The temperature distribution and induced thermal stress are calculated via semi-analytical method in an explicit way. An iterative scheme proposed solve the coupling between fluid flow stress. numerical validated against related analytical solutions. Several cases modeled investigate controlling factors for uniform growth of fractures. Results show that non-uniform spacings proper increasing spacing fractures away from heel wellbore promote comparison spacings. Increasing perforation diameter middle cluster also works. Besides, single-wing fracturing could greatly improve Finally, it shows has significant influence on geometrical size but limited effect path. addition, promotes
