Abstract To analyze the wellbore stability during drilling in methane hydrate-bearing sediments (MHBS)，an analytical wellbore stability model is established by combining the viscoelastic solution with yield criterion. In this model，the unsteady seepage and temperature fields，as well as the rheological properties of the reservoir are taken into account. The analytical solutions of seepage pressure and temperature which are the functions of space and time are obtained by using the method of separation of variables. The phase equilibrium curve of hydrate is applied to determining the dissociation front of hydrate，and the effect of dissociation on viscoelastic parameters is considered. The solutions of time-dependent stress and displacement considering the influence of seepage are analytically derived by Laplace transform technique. The characteristics of seepage and temperature fields are investigated，and the influence of reduction of mechanical parameters of formations on wellbore stability are also studied. The results show that the influence range of seepage and temperature fields increase with time，and the propagation velocity of seepage field is faster than temperature field. When the ratio of shear relaxation modulus between the dissociated and the undissociated region is a constant，the stress of the formation changes monotonously with time. When the reduction of of the dissociated region is small，the equivalent stress at the borehole wall will reach the extreme value before the steady state，and the borehole wall is in high risk of instability.
