Abstract EN
Natural fractures usually develop in shale reservoirs.
Thereby, in the process of hydraulic fracturing, it is inevitable that hydraulic fractures will intersect with natural fractures.
In order to reveal the interaction mechanism between hydraulic-induced fractures and natural fractures, a two-dimensional fracture intersection model based on the extended finite element method (XFEM) is proposed, and the different types of intersecting criteria reported in the literature are compared.
Then, the effects of natural fracture azimuth, fluid pressure in hydraulic fracture, and in situ principal stress difference on hydraulic fracturing are studied in detail.
The results show that the fracture morphology is different under different criteria and working conditions.
And the stress concentration phenomenon mainly concentrates on the tip in the obtuse angle side of natural fracture.
Meanwhile, different fluid pressures in hydraulic fracture can also induce different intersection patterns.
The obtained results in this work are of great benefit to understand the intersection mechanism between hydraulic fractures and natural fractures.
