The analysis of experimental and numerical hydrodynamic researches in flexible pipes of coltubing installations taking into account rheology of liquid for washing is carried out and the way of installation of a suspended cement layer in an operational column is developed.Developed: - scheme of tying the wellhead during hydropico-jet perforation using flexible pump-compressor pipes on wells with abnormally high formation pressures; cementing of wells, which prevents the occurrence of stagnant fluid flows, which involves cementing the casing with two portions of grout and one portion of viscoelastic solution;-technological regulations for the use of hydrogen-generating suspension as a preliminary stage of treatment before the main complex hydrogen thermobarochemical action;-laboratory physicochemical studies have established the difference between the surface properties of inhibited cement stone, resistant to hydrogen sulfide and carbon dioxide, which expands the possibilities of using grout based on Portland cement grade G for fastening oil wells; developed a layout for drilling flexible pipes.
