FIELD: soil or rock drilling.
SUBSTANCE: invention relates to drilling wells and can be used when controlling sinking conditions. Method for regulating the conditions of the drilling process is offered, based on the representation of the bore bit by a three-channel converter of mechanical and hydraulic capacities in two-stage deepening. In this case, the "bore bit – drilled depth" system is considered as a source of speed and is described by the transmission coefficient, in which the ratio 
– a condition that determines the formation and support of the bit mode as a source of speed, and the ratio 
– condition that determines the regulation of the sinking process.
EFFECT: technical effect: the representation of the bore bit as a source of speed, the physical essence of which is described by the transmission coefficient.
