In this paper developed new layout of the bottom hole assembly, consisting of PDC bits, downhole oscillator, screw downhole motor. Proposed bottom-hole of the assembly creates additional dynamic load on the bit, creates low-frequency longitudinal oscillations, reducing the coefficient of friction of the drill string and the borehole wall brings the load to the bit, which is undoubtedly important when drilling horizontal section of the well, applied in the development of viscous oil deposits.
