Abstract
The stability of the walls of wells drilled in a rock mass depends on the stressed state of rocks, their physical, mechanical and rheological characteristics, and the borehole drilling technology. Loss of wellbore stability causes a number of serious complications and accidents in wells. In solving the problem of stability of a wellbore drilled in an ice massif, an attempt has been made to take into account all the main factors influencing the process of wellbore deformation and to obtain a mathematical description of the latter, convenient for practical use in engineering calculations.
