Key words: agitator, vibration effect on the friction coefficient, buckling, ensuring the axial load on the bit.

The article describes the technical means to ensure a required axial load on the bit in horizontal wells. The results of modeling the distribution of axial forces in the drill string when drilling a horizontal well in the case of using a hydraulic agitator designed to reduce the forces of resistance to movement of the drill string along the wellbore are presented. Using the Landmark software product, the WellPlan module simulates the distribution of axial forces in the drill string when drilling a horizontal section with and without an oscillator.
