FIELD: mining.
SUBSTANCE: method includes separation of mud delivered from the well to fractions using system of vibration screens, gathering of sludge separated to fractions in tanks, their weighing using sensors, sensors data are supplied to information processing unit, where difference between current values of output voltage of the force sensor corresponding to the weight of drill cuttings gathered to the special tank, and voltage corresponding to the design rock weight determined by the rated well diameter, and based on this difference increment of well diameter against the rocks easy destructed under mud action is determined as per the mathematical algorithm.
EFFECT: reduced time expenses by combination of the process operations directly during drilling to determine the well profile.
