It is proposed to determine the catastrophic deviations of the intensity of the change in
drilling time of 1 m rocks in the depth of the well using the model of the catastrophe of the "COLLection" of
R.Toma or the model Vapor Pressure. Adjustment of the axial force on the bit according to the developed
methodology allows to provide a stable dynamic drilling mode.
