FIELD: oil industry, particularly methods or devices for cementing, for plugging holes, crevices, or the like.
SUBSTANCE: method involves drilling well up to design depth; lowering production string provided with glass-fiber liner; cementing well. Glass-fiber liner with closed lower end having wall thickness 10-15% smaller than that of production string wall is used. Packer is arranged over glass-fiber liner. Coupling with orifices is located over the packer. Production string is inserted in well so that the coupling is opposite to upper producing formation level. Then packer is installed. Well cementing is carried out by forcing cement via production string, through coupling orifices and hole annuity up to well head. Then the well is left as it is up for cement hardening, glass-fiber liner is drilled and well is completed.
EFFECT: increased producing ability.
