FIELD: soil or rock drilling; mining.
SUBSTANCE: group of inventions relates to a borehole valve system for controlling inflow of fluid medium into a formation and from a formation, as well as a method of controlling fluid flow. Proposed system comprises casing string with inner surface, outer diameter and inner diameter and cross-section defined by inner diameter. Casing comprises a plurality of valves spaced apart to control inflow of fluid from the formation through the casing. Besides, the system comprises a plurality of independent adjustment devices, each of which controls one of the plurality of valves and each of which comprises a housing having an outer diameter of the housing and a cross-section of the housing. At that, multiple independent adjusting devices are fixed inside casing string to allow fluid flow between external diameter of autonomous regulating device casing and casing string.
EFFECT: technical result consists in improvement of efficiency of fluid medium flow control.
