Hydraulic fracturing is an important technique in unconventional petroleum reservoir development. In this paper, a numerical algorithm is used to study the interaction of a propagating hydraulic fracture with a natural fracture in an infinite saturated porous domain. It is shown that this model can appropriately simulate two possibilities which might occur during the hydraulic fracturing of naturally fractured reservoirs. The variations of bottom-hole pressure and crack mouth opening displacement through time are completely described. It is shown that how the coupling between fluid pressure and discontinuities deformation influences the variation of bottom-hole pressure as a measurable parameter through time.
