FIELD: mining.
SUBSTANCE: control over drilling job comprises the construction by the first and second and first make-of-bottom-string transducers of the first and second time well-logging records describing the drill well parameter in the drilling path. Computer processor is used to define said make-of-bottom string while, at drilling, it executed the time shift by comparison of the first and second time well-logging records. The first and second time well-logging records are shifted to maximise the coefficient of the first and second time well-logging records correlation and to define the drilling rate and preset spacing between aforesaid transducers proceeding from the defined time shift.
EFFECT: determination of the drilling rate and depth.
