The considered frequency characteristics of drilling column, as object of management is in the process of deepening wells. It is shown that in the absence of friction in the process of deepening wells model columns degenerates into a structurally unstable link. To increase stability of the drilling process requires entry of correcting links to the reduction of the order of astatism frequency structure functions.

Keywords: stability of the drilling process, the frequency characteristics of the drill string
