FIELD: oil and gas industry.
SUBSTANCE: invention refers to methods of isolation of problem zones with well boring, and also with wells repairing by shutters from profile casing pipes. At method realisation sections of profile pipes are jointed to final cylindrical sections, shutter is dropped in the necessary spacing of capping, and it is corrected by preliminary overpressure in the top section, shutter sections are densely held down to hole walls. Quality and reliability of installation are improved, expenses are relieved.
EFFECT: quality and reliability improvement of profile capping installation in the hole; installation expenses decreasing.
