Abstract

It has carried out an analysis of the influence of surface phenomena on the stability of the wellbore. It has shown that a rock mass, which is an elastic half-space, is loaded with internal forces of the gravitational field, and conditions of plasticity or rock flowage can not appear inside of it. The concentration of stresses on the wellbore is investigated
