FIELD: mining.
SUBSTANCE: method for visual demonstration of interconnection between alignment of a tool face and position of a drive sub by means of continuous reception of electronic data including data on drive sub position and at least data of gravitation alignment of tool face or data of magnetic alignment of tool face and display of electronic data on a user's display in a chronological order to show data of last measurements and multiple immediately preceding measurements.
EFFECT: more accurate measurement of interconnection between position of a tool face and a drive sub for more accurate and efficient directed drilling.
