Many factors influence an efficiency of bottom-hole deepening process, among them - axial weight on drilling bit, bit speed, bottom-hole cleaning conditions and well geological conditions. However, existent methods of calculations of the drilling practices and strength calculation dо not consider the random character of the coefficients included in these dependences. The authors of the paper suggest the modеl of bottom hole-deepening, which takes into account dynamic parameters of drilling tools and еnаblе to forecast the drilling indexes with modification of the bottom-hole assembly and drilling practices for different types of drilling.
