Abstract—The results of the numerical solution of the problem of static loading of the bottom-hole assembly (BHA) by axial load are given, taking into account the contact interaction with the borehole wall. The numerical solution of the presented problem is important in the process of preparing for drilling various types of wells. The finite element method is used as the main computational research method. A finite element model of a special type, designed to simulate the contact interaction of a drill string with a borehole wall, is presented. A computational algorithm for numerical simulation of nonlinear deformation of a drillstring based on the use of linear beams and nonlinear rod finite elements is proposed. The developed algorithm allowed the calculation of the forces acting on the bit, as well as the calculation of the drillstring displacements inside the wellbore in a two-dimensional formulation. The results of computational experiments are presented.
