Key words: well, drill pipes, threaded joint, accidents, nipple, coupling, torque at screwing, sealness, wear resistance, operational life.

The improved threaded conical tool joint of drilling pipes applied while drilling deep and complex oil and gas wells as well as in the construction of side boreholes and multi-hole wells is designed by authors.

The application of developed threaded lock joint of drilling pipes while boreholes deepening will allow increasing the solids-carrying capacity of the joint, sealness and increasing its operational life.
