FIELD: oil industry.
SUBSTANCE: group of inventions relates to oil industry and can be used for oil production from several formations of one well. Multiple-formation deposit is opened by drilling of production well with its subsequent completion either is repeated completion in already existing or in casing string. In well shaft between beds isolating elements are installed. In well bore and/or between insulating elements are arranged, at least one section with adaptive control system of influx. Adaptive control system of influx is equipped with shutoff valve, then well is operated single-lift method with tubing string. At that, additionally used during well operation monitoring of well operation. Used device represents throttling rings with different hydraulic characteristics and valves with fixed position of gate.
EFFECT: technical result consists in improvement of efficiency of oil from multi-formation deposit.
