FIELD: oil and gas industry.
SUBSTANCE: method includes isolation of some well sections, and monitoring of their inflow. Preliminary place of the problem section is determined, and device is run in the well, at least closing zone of the problem section inside the first completion. The device contains isolating elements located above and/or below the problem section, elements of second completion and suspension. The isolating elements and suspension contain sealing devices, isolating along the internal surface of the well string.
