SUMMARY:

Directional drilling techniques are applicable in fields, such as petroleum, buildings and the mineral extraction industry. Compared to vertical drilling, directional drilling is much more complex. The curvature of the well axis passing through the stratified rock mass causes the conditions around its cross section to be strongly anisotropic. Not infrequently, the same rock material in each layer exhibits anisotropic properties. Proper determination of the stress, strain, and displacement states around the borehole is critical in the design of directional boreholes. Numerical analysis tools that take into account the rock mass structure and rock mechanical properties along the well path are used for this purpose. This paper aims to numerically evaluate the structural stability of rock masses around a directional well using the Finite Element Method. The calculations are conducted with linear elastic and viscoelastic constitutive models, used in the rock strata models. Based on the results, the influence of rock behavior on the stability of the directional well is discussed.
