Criteria for limiting casing stress at directional well casing. Composition and technology of preparation and installation of fuel and bituminous and hydrophobically bituminous vessels for well walls strengthening were elaborated. Device design for sealing of cracks in formations during well drilling was developed and patented. New model of drilling mud composition choice for producing horizon discovery was presented. Evaluation method for pipe string twisted area stress and installation of peak stress influence on long life, taking into consideration well wall friction was elaborated. Analysis method for stress deformation state of dimensional twisted drill string and equation of its movement in directional well, based on analytical correlation of active friction forces and kinematic parameters of its rotation by the upper drive system was presented.
