FIELD: oil production. SUBSTANCE: additional glass reinforced plastic casing string is sunk in process of repair of oil production well. Pipes made of corrosion-resistant steel or glass reinforced plastic are lowered into perforation intervals with due account of period of operation of well while transferring from one operated oil pool to another. Centering mounts made of synthetic materials, for example, polyamide materials, are mounted along entire length of tubing string to diminish mechanical action of suspension of tubing string and pump on internal surfaces of reinforced plastic casing string. EFFECT: raised corrosion resistance and operational life of production well.
