However, the two influencing factors have not been considered in the existing fracturing pressure calculation model. So it is necessary to incorporate the two factors into the model. Based on the poroelasticity theory, the stresses induced by the in-situ stress and the fluid flow are calculated. And the temperature stresses are calculated based on the theory of elasticity. According to the superposition principal, the effective stresses on the borehole wall are obtained. With the considerations of the reservoir temperature and the plugging, a fracturing pressure analytical model during the waterflooding is established. This analytical model is verified by the conventional calculation model. The influences of the reservoir temperature and the plugging are analyzed. It is shown that the fracturing pressure decreases linearly with the decrease of the water temperature. And with the increase of the elastic modulus and the coefficient of linear expansion, the change extent of fracturing pressure is getting larger. Compared with the formation plugging zone, the filter cake thickness and the permeability have a greater impact. With the increase of the filter cake thickness and the decrease of its permeability, the fracturing pressure would increase. If the filter cake exists, the fracturing pressure decreases with the increase of the plugging zone radius. However, the permeability of the plugging zone has little impact on the fracturing pressure. And the plugging zone in the formation would not affect the fracturing pressure if the filter cake does not exist., authors=SUN Jin¹, PENG Chengyong², YU Baohua¹, DENG Jingen¹, authorsList=SUN Jin, PENG Chengyong, YU Baohua, DENG Jingen, authorCompany=1.
