FIELD: oil producing industry. SUBSTANCE: centralizers are mounted on worn-out rod and tubing sections. The number, type and layout of centralizers along the string are influenced by actual operational loads applied to the centralizers, by their rated loads, and by the borehole geometrical profile, and are determined from a dependence presented in the description. EFFECT: increased efficiency of assembly work. 2 tbl, 3 dwg
