Annotation:

Mining and geological conditions of drilling deep and ultra-deep oil and gas wells are becoming increasingly complex, approaching, and even becoming extreme, which are characterized by high hydrostatic pressure and high temperature at the bottomhole. In such conditions, as a rule, there are sections of very hard and extremely hard rocks according to the M.M. Protodyakonov hardness scale. These conditions require ensuring a bit high rotation speed, which is only guaranteed by the turbine drilling method. The authors of the article consider a spindle section capable to operate not only at high speeds (up to 2500 rpm), but also in extreme geological-technological drilling conditions. Calculations are given for a spindle section, which will subsequently be included in a high-speed turbo-drill to be used for extremely hard rocks destruction. Currently, the creation of a turbine section is already possible, so optimization of the spindle section is relevant. It is required for transmitting torque from the turbine section, stabilizing the engine operation, radial and axial vibration samortization as well as stabilizing the operation of the hydraulic engine and the drilling process as a whole.
