FIELD: well drilling; applicable in well drilling under sharply variable conditions. SUBSTANCE: method consists in assembly of working members with frequencies of natural vibrations relating to one another as series of random numbers whose quantity of members is limited by length of dynamically disturbed part of compressed part of drill string by compression elastic waves at preset drilling conditions. EFFECT: higher efficiency of assembly operation due to reduced effect of random factors on operation of downhole drill string assembly under sharply variable conditions.
