FIELD: oil and gas production.
SUBSTANCE: group of inventions refers to oil and gas producing industries, particularly to tools for survey of reservoirs and for sampling. The group of inventions consists of a tool, of a method of evaluation of parametres of underground reservoir, and of a method of well sampling. The facility includes a unit lowered into the well on a cable; the unit is installed at a preset position in the going to the underground reservoir borehole of the well; the unit is equipped with a boring tool recovering samples of core from the reservoir and a tool for reservoir testing designed to sampling of fluid mediums in the reservoir; in working position this tool is connected with the boring tool recovering samples of core.
EFFECT: increased efficiency of operation, reduced dimensions, combining separate tools in the same component.
