FIELD: soil or rock drilling.
SUBSTANCE: group of inventions relates to the method of drilling a well bore and to the drilling rig systems. In the method of drilling a well bore, the first distance is measured, at which the drilling device is raised in connection with the drilling rig, determining the load on the bit in the drilling rig, determining the second distance for lowering the drilling device so that the drilling bit at the lower end of the drilling rig approaches the bottom of the wellbore, based on the first distance and load on the bit and the descent of the drilling device to the second distance.
EFFECT: technical result is to maintain operational safety.
