This article presents the rationale and relevance of the use of an improved threaded keyhole conical connection of drill pipes for the oil and gas industry. The proposed threaded joint for drill pipes is characterized by an increased service life and a high rate of bearing capacity of the threaded joint in the conditions of drilling wells with complex spatial parameters, including when drilling sidetracks, horizontal and branched trunks of deep oil and gas wells.
