Abstract: The present invention relates to the oil-and-gas industry, specifically, to the development and exploitation of oil reservoirs with various permeability zones, including by means of lateral horizontal bore segments. The method of interval action on horizontal wells includes the steps at which a horizontal segment of the wet is bored preliminarily, the same segment being constructed through the formation with various permeability zones. Geophysical survey is conducted and the number of the oil recovery intervals of various categories and their lengths are determined. A tail pipe (or tail filter) of the casing string with packers and drive shoe is lowered down and installed in the horizontal segment of the well. A pump and an assembly on the pipe string is lowered down into the well, the same assembly consisting of the electric valves with the pressure and temperature sensing devices, the cable and the packers separating the annular space of the well.
