The Model of in-situ Stress Considering linear elastic material, the surrounding rock stress of the vertical well under the in-situ stress is: (1) Where, sH, sh, sv are maximum horizontal in-situ stress, minimum horizontal in-situ stress and vertical stress, is the distance between an arbitrary point and the center of the borehole; is the radius of the borehole; is radial stress; is circumferential stress; is shear stress.
(2) Where, is the pore pressure at an arbitrary point near the fracture formation; is the constant boundary pressure; is the viscosity of crude oil; Considering areal radial seepage and the effect of fluid-solid coupling, the diffusion equation of the fluid is: (3) Assumption that the formation is two-dimensional isotropic material, we can get the distribution of stress caused by pore pressure induced stress and in-situ stress according to generalized hook ' s law and compatibility equation
