FIELD: geological investigations; method for obtaining continuous information on mechanical and physical properties of ground in course of well sinking. SUBSTANCE: drilling tool together with rock-breaking member and measuring device 6 is lowered into well, and the measuring device is forced into ground with constant advance value h with respect to rock-breaking member. Simultaneously, data on ground mechanical and physical properties are transmitted and recorded, and ground is broken. Axial force for embedding the measuring device is transmitted from rotating drilling tool. EFFECT: provision of continuous information on ground mechanical and physical properties directly in the process of well drilling. 2 dwg
