description FIELD: oil and gas extractive industry. ^ SUBSTANCE: method includes drilling of operation well, forming in productive bed within feeding range of operation bed of at least one level of main draining system by drilling horizontal shafts from operation well above productive bed, and driving said shafts in radial direction, also, to prevent fast watering of well, before start of its operation, hollows of horizontal shafts are isolated from operation well. In productive bed in feeding range of operation well on one level with main draining system additional draining system is formed, one additional level of main and/or additional draining systems is formed, hollows of operation well and horizontal shafts is additionally connected by hydraulic fracturing of bed, before isolation of hollow of operation well from hollow of horizontal shafts, filter is mounted in the latter, as well as porous oil-attracting hydro-repelling material. ^ EFFECT: higher efficiency and durability. ^ 6 cl, 2 dwg, 1 ex
