Abstract

In this paper, the wellbore stability in complex geological condition is studied by finite element numerical simulations. A more real rock material model based on transversely isotropic constitutive relations and the failure criteria for directional tensile strength and shear strength are inserted in the computational model. Numerical examples show that the shear failure induced by low strength on the bedding plane is the main reason to initiate the wellbore instability in complex geological formations.
