Method for optimization of the process of well drilling includes determination of specific volumetric work for rock destruction, choice of rock-destruction instrument for conditions of specific geological section, well boring. One determines the physical-mechanical properties of rocks of specific geological section (hardness, abrasivity and coefficient of plasticity); at that the type of rock-destruction instrument is chosen by the method of destruction of rock (cutting or chop-milling action) by the lowest value of specific volumetric work for rock destruction and coefficient of plasticity of rock of specific geological section. Structure of rock-destruction elements is chosen through respective values of hardness and abrasivity of rock of specific geological section, well drilling is performed by the rock-destruction instrument chosen.
