The process of borehole deepening in conditions of changing geological characteristics of formations can be classified as chaotic.
The use of the synergetic theory of information for assessment of well logging data allows to analyze the dynamic mode of well drilling and provide recommendations on selection of BHA main elements. To assess the intensity of weight-on-bit change, it is recommended to use the limited growth model known as Verhulst’s equation. Regulation of the weight-on-bit according to the proposed method allows to achieve a stable dynamic mode of drilling of vertical and directional wells.
Key words: dynamic stability; synergy principles; chaotic regime; fractal dimention; 3D.
