Abstract
The research carried out made it possible to improve the technology of drilling wells in difficult mining conditions. The proposed approach is based on a systematic approach to the consolidation of borehole walls and its separation from exposed systems of reservoir rocks. The studies cover the unstable rocks of the sedimentary cover of the eastern edge of the Russian platform and the conditions for drilling wells in them. The holes are oriented and horizontal. Field tests have shown that the proposed technical and technological solutions enable the successful solution of the set scientific and technical problems. It is recommended to test the proposed solutions in other regions of Russia and abroad. Keywords: well construction; geomechanics; wall stability; improvement; systemic approach; complex mining conditions.
