Abstract
The most similar prototype models of foreign and domestic core orientators have been analyzed, and a model of a new automatic core orientator created by the author is presented. It provides continuous drawing of three lines on1,5 metercore surface section by diamond cutters in borehole drilling, secures accurate core orientation, decrease in time and general costs of this work.
