Drilling tool sticking is one of the most common, complex, and time-consuming incidents (accidents). Therefore, developing a technology that prevents sticking during wells construction is an important task and requires a detailed study of the main causes of their occurrence. Based on the conducted analysis, the authors of the article present a classification of sticking types and identify the main causes of differential sticking occurrence, most typical for the fields in the Timan-Pechora oil and gas province. It has been confirmed that the main causes of differential sticking are: rocks permeability, pressure drop in the wellbore-formation system, the area and time of the tool contact with the filter cake, drilling fluid parameters, formation temperature, mechanical friction forces, and adhesive interactions at the "metal–cake" interface. It has been revealed that an increase of pH from 9 to 13,2 brings the decrease of adhesive interaction intensity and 2 times increase of the connection failure of polymer-clay drilling fluids and 3,1 times increase of highly alkaline drilling fluids. To prevent differential sticking, it is proposed to use permeable formations colmatation by means of a clay-free, highly alkaline drilling fluid and a biopolymer colmatation mixture transformed from it.
